Abstract:
The article is devoted to the study of methods for modeling the operation of rectification columns using the HYSIS application software package. Such studies are very important not only for design, but also for the functioning of existing industries. The article proposes to use for combining nozzle devices in the concentration part of the column, and plate-shaped structures in the distant part of the column for more efficient and stable operation of distillation columns. To determine the hydrodynamic parameters of the operation of distillation column, a technique of determining the range of stable loads and the position of the operating point inside or outside the range of stable loads was taken. A column model was constructed using the HYSYS software package for separating gas mixtures with various contact devices: sieve trays, Rashig ring nozzles. Experiments for the same type and combined contact devices were carried out and their comparison was carried out in terms of hydraulic calculation and operating range. As a result of experiments with the use of the HYSYS software package, it was shown that the combined arrangement of contact devices can provide a stable hydraulic mode, in contrast to the use of similar contact devices.

Abstract:
Determinations of the temperature effect on glycerol nitration processes have been done with two methods: the HYSYS predictions and the laboratory experiment. The aim of this study was to compare prediction method and laboratory experiment method. The highest equilibrium conversion from HYSYS predictions was obtained in the range of equilibrium temperature of 10 to 20 °C. The laboratory experiments also described that nitration of glycerol with nitric acid should be carried out at reaction temperature of 10 to 20 °C. HYSYS that was used to predict the results of experiments in the laboratory can reduce the laboratory work with minimize the range of operating conditions studied. HYSYS exactly predict temperature of nitration of glycerol. The difference in conversion between two methods due to the equipment that was used in the experiments, procedure of experiments and the accuracy of analysis.

Abstract:
The article shows examples of the use of Aspen Hysys software for optimization of the AVT-3 and AT-2 crude oil distillation units at Atyrau Oil Refinery. The Aspen Hysys software was implemented at the Atyrau Refinery for the first time.Calculations were carried out to optimize AVT-3 and AT-2 crude distillation units of the Atyrau refinery with the construction of a model in Aspen Hysys. As a result of the calculations, the possibility of improving the efficiency of individual parts of units was revealed, pilot runs on the units were carried out to confirm. During the pilot run on the AVT-3 unit, a restriction was revealed on regulating the temperature of the cube of the steam column, which affects the stabilization of the kerosene fraction beginning boiling point. During the pilot run at the AT-2 unit, it was revealed that an increase in steam consumption in the main atmospheric oil distillation column contributes to a decrease in the content of light fractions in straight-run fuel, while the yields of gasoline and kerosene-gasoil fractions increase. Thus, the positive effect of Aspen Hysys application at the Atyrau refinery for optimization of crude oil distillation units and identification of technological limitations is shown.

Abstract:
In this paper, reactive distillation column for the production of ethyl acetate from ethanol and acetic acid has been simulated by the simulator tool of HYSYS. This reactive distillation is a promising operation whereby reaction and separation take place within a single distillation column. The thermodynamic properties are calculated with the Wilson, NTRL and UNIQUAC Property Package models which are available in HYSYS simulator program. The effects of water content in feed, bottom temperature and reflux ratio on top temperature and conversion of ethanol are studied when using three thermodynamic models and three feed statuses (upper, intermediate and spilt).The results showed that the best conditions are: bottom temperature (83-86)0C, reflux ratio (2-5) without water content in feed at spilt condition using Wilson as the best model. The study gives evidence about a successful simulation with HYSYS because the results are close with the experimental data of (Calvar et al)[18

Abstract:
<p>The process simulators are increasingly used in the activities of design and analysis of industry operations. Recently, several commercial simulators have been developed, including HYSYS, which was initially developed for applications related to petrochemicals, but with modifications can be used to simulate the operating conditions of other areas such as the food industry. The evaporation of orange juice is a processing step that aims to concentrate the separation of water by heating the mixture, with high energy consumption. Therefore, processes modeling and simulation using simulators such as HYSYS becomes very attractive due to the possibility of studies in the plant without the need of experimentation, since the process being modeled it is possible to obtain fast and reliable information. The results of this study showed that hypothetical orange juice modeled in HYSYS through the sucrose solution in water represented well and the real juice obtaining a deviation less than 10% for the property thermal conductivity. The model of falling film evaporator for concentrating orange juice built in HYSYS by the association of the heat exchanger and flash separator vessel proved to be fairly consistent through the simulations with the experimental data of the process which indicates great potential for use as analysis tool, simulation and optimization of the concentration of orange juice in industrial evaporators.</p><p>&nbsp;</p><p>DOI: http://dx.doi.org/10.14685/rebrapa.v2i1.43</p>

Abstract:
This work presents a theoretical investigation of the simulation of Sulfuric acid process plant. In the production of the acid in contact process liquid sulfur is sequentially oxidized to Sulfur tri oxide via an exothermic reaction which is absorbed by 98% Sulfuric acid in an absorption tower. In this research Aspen One V7.2 has been successfully used to design every sub-process of the sulfuric acid plant in one integrated environment. In order to simulate the process as accurately as possible COM thermo was selected as advanced thermodynamics. Electrolyte NRTL and Peng-Robinson were used for liquid and vapor phase respectively as fluid package and HYSYS properties were used for simulation. The simulation of sulfuric acid process included automatic chemistry generation and the capacity of handling electrolyte reactions for all unit models. Aspen-HYSYS provides specialized thermodynamics models and built-in data to represent the non-ideal behavior of liquid phase components in order to get accurate results. Material and energy flows, sized unit operations blocks can be used to conduct economic assessment of each process and optimize each of them for profit maximization. The simulation model developed can also be used as a guide for understanding the process and the economics, and also a starting point for more sophisticated models for plant designing and process equipment specifying.

Abstract:
In this time of energy crisis low production rate against the increasing demand of the gas production regularly hampers both the domestic and industrial operations since natural gas is the major power source of this country. Unless other power source is developed, natural gas is our only hope. Almost all the existing processing plants are now operating beyond their capacities. Nonetheless there has been a dwindling situation in the gas production. Besides political indecision regarding new establishment of gas plant and other power source have made the situation nothing but complicated. In such a case an idea of optimization of the gas processing plant will surely pave a way to a sustainable solution. This project has the intention to carry out the simulation of the Bakhrabad gas processing plant (at Sylhet) using the Aspen-HYSYS process simulator. The steady state simulation of the gas processing plant shall be performed based on both the design and physical property data of the plant.

Devido à formulação de leis mais rigorosas com relação à preservação do meio ambiente, sobretudo no que diz respeito ao teor de enxofre presente nos combustíveis fósseis, as refinarias de todo o mundo estão sendo desafiadas a adequarem seus processos de refino a condições operacionais mais severas, que permita a produção dos derivados do petróleo de ultrabaixo teor de enxofre. Maior atenção é dada aos destilados intermediários, tais como a gasolina e o óleo diesel, por apresentaram vasta empregabilidade no setor de transporte, que é por sua vez o setor da economia que mais consome combustíveis fósseis. Sendo o derivado de petróleo mais consumido no setor de transportes e responsável por grande parcela da emissão de compostos tóxicos durante a queima em motores de combustão, o óleo diesel é hoje submetido a normas legais que limitam o teor de enxofre para 10 mg/kg, o que torna mais difícil o processamento do destilado, uma vez que o petróleo utilizado está cada vez mais pesado. Diante disso, no presente trabalho uma unidade de hidrotratamento de diesel oriundo de um petróleo pesado foi modelada e simulada em estado estacionário, utilizando o software Aspen HYSYS® como ferramenta computacional, sendo avaliados os principais parâmetros de processos e o desempenho da unidade frente a suas variações, com o objetivo de determinar condições de trabalho que garantissem uma produção de óleo diesel com no máximo 10 mg/kg de enxofre, obtendo simultaneamente um alto rendimento de produção. Inicialmente foram propostas algumas hipóteses e as condições operacionais da unidade com base em dados relatados na literatura. De acordo com as condições de trabalho empregadas, foi possível atingir um óleo diesel tratado com 3,55 mg/kg de enxofre, 3,21 mg/kg de nitrogênio e 0,03 mg/kg de água, alcançando uma recuperação de 81,00 m/m% dos compostos constituintes da faixa de destilação do óleo diesel presentes na carga da unidade. Em conjunto também foi analisado o gasto energético da unidade a fim de se obter uma estimativa da viabilidade econômica do processo, sendo constatado que as utilidades e as colunas conferem os maiores consumos de energia. Com base nas análises de sensibilidade realizadas, ainda foi possível estabelecer a relação entre os resultados analisados em cada seção da unidade e os parâmetros envolvidos no controle dos mesmos. E a partir das respostas obtidas, foi elaborada a otimização do processo a partir da Metodologia de Superfície de Resposta através do emprego do software Statistica, conferindo condições mais eficientes de trabalho, garantindo assim a produção de um óleo mais purificado, contendo cerca de 0,10 mg/kg de enxofre, com maior recuperação dos compostos do diesel (aproximadamente 85,11 m/m%), além de gerar menores gastos energéticos, alcançando uma redução de 16,54 % referente à simulação mantida nas condições padrão de trabalho. Em adição, no caso otimizado ainda foi possível atingir maiores valores de recuperação dos demais cortes de petróleo constituintes da alimentação da unidade.
Due to the development of stricter laws regarding the preservation of the environment, especially in relation to the sulfur content in fossil fuels, refineries around the world are being challenged to adapt their refining processes to more severe operating conditions, that they are able to product ultra-low sulfur petroleum distillates. Greater attention is given to intermediate distillates, such as gasoline and diesel oil, due to their extensive employment in the transport sector, which is the sector of the economy that consumes more fossil fuels. Diesel oil is the petroleum product most consumed in the transportation sector and accounts for a large portion of the emission of toxic compounds during combustion in engines, this way diesel is now subject to legal rules that limit the sulfur content to 10 mg/kg, which complicates the processing of the distillate, since the petroleum used is heavier. Therefore, in this paper a unit of diesel hydrotreating come from a heavy oil was modeled and simulated in steady state, using the Aspen HYSYS® software as computational tool, and the main process parameters and performance unit against their variations are evaluated, by purpose of determining working conditions that would ensure diesel production with a maximum of 10 mg/kg of sulfur, at the same time achieving a high production yield. Initially some hypotheses and unit operating conditions were proposed based on data reported in the literature. According to the working conditions employed, it was possible to achieve a diesel fuel treated with 3.55 mg/kg sulfur, 3.21 mg/kg nitrogen and 0.03 mg/kg water, obtaining 81.00 wt% recovery of constituent compounds of distillation range of diesel oil present in the unit load. Together it was also analyzed the energy expenditure of the unit in order to obtain an estimate of the economic viability of the process, and it was found out that the utilities and columns required the highest energy consumption. Based on the sensitivity analysis performed, it was still possible to establish the relationship between the results analyzed in each section of the unit and the parameters involved in their control. Since the answers were obtained, the optimization of the process through the Response Surface Methodology by using the Statistica software was developed, providing more efficient working conditions, thus ensuring the production of more purified oil, containing about 0.10 mg/kg of sulfur, with greater recovery of the compounds of diesel (about 85.11 wt%), besides generating lower energy costs, achieving a reduction of 16.54% referring to the simulation maintained in standard working conditions. In addition, the optimized case was still possible to achieve higher recovery value of other of petroleum distillates, which were constituents of the unit feed.

Neste trabalho, foi elaborada uma base de dados de parâmetros de interação binária de diferentes regras de mistura, para as equações de estado de Soave-Redlich-Kwong (SRK) e Peng-Robinson (PR), a partir de dados experimentais de sistemas binários e multicomponentes de hidrocarbonetos, N2, CO2, água, β-caroteno, etanol, acetona e metanol, com objetivo de aplicar em simulações com o Aspen Hysys aos processos de fracionamento do gás natural em um processo de turbo-expansão simplificado; de fracionamento de óleo, gás e água, em separador trifásico, de extração com CO2 supercrítico de acetona de uma solução aquosa e de β-caroteno de uma solução aquosa, em coluna de multiestágios em contracorrente. De modo geral, não ocorreram diferenças significativas na predição do equilibro de fases dos sistemas binários estudados, para ambas as equações, com as regras de mistura quadrática, Mathias-Klotz-Prausnitz (MKP) com dois e três parâmetros. Cabe destacar que a regra de mistura MKP com 3 parâmetros de interação binária apresentou os menores erros absolutos para os sistemas binários de hidrocarbonetos e CO2/ hidrocarbonetos. Para os ajustes de dados de equilíbrio dos sistemas multicomponentes de hidrocarbonetos, a equação de SRK combinada com a regra de mistura quadrática com 2 parâmetros de interação binária, foi a que apresentou os menores erros médios para os sistemas ternários e para o sistema com 5 componentes em ambas as fases. No estudo de caso do separador trifásico a equação de SRK com a regra de mistura RK-Aspen foi a que apresentou a maior separação da fase aquosa de todas as simulações (285,68 kg/h) contra 256,88 kg/h para a equação SRK, 249,81 kg/h para a equação PR e 152,90 kg/h para a equação PRSV, confirmando a grande influência do uso da matriz de parâmetros de interação binária determinada neste trabalho, com destaque para os parâmetros que representam as interações entre os hidrocarbonetos com a água. Os resultados das simulações com a planta simplificada de turbo-expansão estão de acordo com a análise descrita na literatura, apresentando as seguintes taxas de recuperação de etano: 84,045% para PRSV, 84,042% para SRK, 84,039% para TST e PR e 83,98% para RKAspen. O produto final da simulação publicada na literatura para o fracionamento de uma solução aquosa de acetona utilizando o processo de extração com CO2 supercrítico consistiu na corrente de saída do fundo da coluna de destilação a 65 atm (6586 kPa), com uma composição de 67,67 % de CO2 (74,3 kg/h), 31,11% de acetona (34,15 kg/h) e 1,21% (1,33 kg/h) de água em base mássica. Na simulação com o Aspen Hysys a corrente de saída da coluna de destilação foi submetida a um conjunto de separadores flash para a separação do CO2 atingindo a recuperação de 27 kg/h de acetona em três correntes (11,14 e 15) com menos de 5 kg/h residuais de CO2 e 0,8 kg/h de água. O fracionamento da solução aquosa de β- caroteno foi simulado com o Aspen Hysys, com uma coluna de múltiplos estágios em contracorrente e um separador flash vertical para a separação do CO2. As simulações convergiram com, no mínimo, cinco estágios. Foi obtida uma corrente de fundo (produto) do separador flash com 97,83% de β-caroteno contra 89,95% em massa, para a simulação de um extrator de um único estágio publicada na literatura.
The purpose of this work was to elaborate a database of binary interaction parameters of different mixing rules, for the Soave-Redlich-Kwong (SRK) and Peng-Robinson (PR) equations of state, using experimental data of binary and multicomponent systems of hydrocarbons, N2, CO2, water, β-carotene, ethanol, acetone and methanol, in order to apply in simulations with the Aspen Hysys fractionation processes, of natural gas into a simplified turbo-expansion process; fractionation of oil, gas and water, in three-phase separator, supercritical CO2 extraction of acetone from an aqueous solution and β-carotene from an aqueous solution in multistage countercurrent column. In general, there were no significant differences, to both equations, in the phase equilibrium prediction of the binary systems studied, between the quadratic and Mathias-Klotz-Prausnitz (MKP) mixing rules with two and three parameters. It is worth mentioning that the MKP mixing rule with 3 binary interaction parameters presented the smallest absolute errors for hydrocarbon binary systems and CO2/hydrocarbons systems. For the settings of hydrocarbons phase equilibrium multicomponent systems data, the SRK equation combined with quadratic mixture rule with 2 binary interaction parameters, was presented the lowest average errors for ternary systems and for system with 5 components in both phases. In the case study of three-phase separator the SRK equation with the mixing rule RK-Aspen was the one that presented the greater separation of the aqueous phase of all simulations (285.68 kg/h) against 256.88 kg/h to the SRK equation, 249.81 kg/h for the PR equation and 152.90 kg/h to PRSV equation, confirming the great influence of the use the binary interaction parameters matrix determined in this work, with emphasis on the parameters that represent the interactions between the hydrocarbons with water. The results of the simulations with the simplified plant turboexpansion are according to the analysis described in the literature showing the following recovery rates of ethane: 84.045% to PRSV, 84.042% for SRK, 84.039% for TST and PR and 83.98% for RK-Aspen. The final product of the simulation published in the literature for the fractionation of an aqueous solution of acetone by using supercritical CO2 extraction process consisted in the output current from the bottom of the distillation column at 65 atm (6586 kPa), with a composition of 67.67% CO2 (74.3 kg/h), 31.11% of acetone (34.15 kg/h) and 1.21% (1.33 kg/h) of water in mass base. In the simulation with Aspen Hysys the output current of the distillation column was subjected to a set of flash separators for separation of CO2 reaching the recovery of 27 kg/h of acetone in three currents (11.14 and 15) with less than 5 kg/h CO2 waste and 0.8 kg/h of water. The fractionation of aqueous solution of β- carotene was simulated with the Aspen Hysys, with a multistage countercurrent column and a vertical flash separator for separation of CO2. The simulations have converged with a minimum of five stages. It was retrieved from an underflow (product) flash separator with 97.83% of β-carotene against 89.95% by mass for the simulation of an extractor of a single stage published in the literature.

A tecnologia de produção de combustíveis sintéticos iniciou seu desenvolvimento a partir de 1919, na Alemanha, tendo o carvão mineral como insumo para a gaseificação. Com o passar dos anos novos insumos foram utilizados, como a biomassa e o gás natural, cada um com rotas tecnológicas próprias. Com o uso do gás natural esta rota tecnológica é conhecida como Gas-To- Liquids (GTL) sendo uma transformação química que gera faixas de hidrocarbonetos líquidos e estáveis à temperatura e pressão ambientes. Este processo tem como etapa principal etapa à reação de Fischer Tropsch (FT), pois transforma gás síntese resultante da reforma do gás natural em hidrocarbonetos líquidos que ao serem refinados tornamse importantes produtos para indústria petroquímica, de transporte e áreas afins. Essa transformação pode ser realizada no próprio local de produção do gás, evitando investimentos e problemas ambientais na construção de gasodutos. No Brasil, o gás natural apresenta crescente incremento da sua produção, e forte aumento das suas reservas, como por exemplo, a descoberta do pré-sal e o gás natural presente pode estar tanto associado quanto não-associado ao petróleo. Devido às estruturas de plataformas normalmente se localizarem em áreas remotas, torna-se custoso o aproveitamento desse gás que é liberado pela produção do óleo, sendo o mesmo queimado ou ventado. Devido às restrições estabelecidas pela legislação ambiental, a queima do gás natural nas plataformas de produção passa a ser problemática e crítica. Este trabalho teve como objetivo desenvolver e avaliar por meio de simulação computacional uma planta de GTL na produção de hidrocarbonetos líquidos via a reação de FT e utilizá-lo na otimização do processo, na busca por um processo com maior capacidade produtiva e com menores gastos energéticos, gerando um melhor aproveitamento do gás natural, produzindo materiais com maior valor agregado. Foram utilizados os softwares de simulação MATLAB® e HYSYS®, que permitiram a analise de resultados satisfatórios para a conversão e distribuição de hidrocarbonetos gerados em comparação com o descrito pela literatura. A qualidade dos hidrocarbonetos gerados foi analisada pela avaliação do diesel obtido.

Nos últimos anos o biodiesel se tornou uma alternativa para a demanda crescente de combustível. O próximo passo é conseguir produzir um biodiesel economicamente competitivo com o diesel fóssil em um processo em nível industrial. Este trabalho visa estudar do ponto de vista computacional, uma planta piloto de biodiesel, simulando o processo desde a reação de transesterificação de óleos vegetais, chegando até a purificação do biodiesel, utilizando o APEN/HYSYS. Além disso, foi feito o estudo da viabilidade econômica preliminar da mesma, fazendo-se uso do custo anualizado total unitário CATU. Os resultados das simulações foram comparados com os resultados obtidos numa planta piloto montada em Pernambuco/Brasil. Em seguida, foi comparada a viabilidade econômica da planta piloto, com uma planta operando com uma coluna de destilação reativa para produção do referido combustível. Os resultados mostraram que a destilação reativa é um processo mais econômico para a produção do biodiesel do que em um processo em batelada

O trabalho realizado foi desenvolvido no âmbito de um estágio curricular de seis meses efectuado no Steam Cracker da Repsol Polímeros de Sines. O seu principal objectivo foi a optimização energética da zona fria do Steam Cracker, que tem como produtos principais, o etileno, propileno e 1,3-butadieno. Para tal começou-se por realizar uma simulação em Aspen HYSYS de toda a zona fria de modo a que servisse de base para a realização dos estudos necessários referentes à optimização energética. Sendo validada a simulação iniciaram-se os Case Studies de modo a perceber-se onde se deve actuar e que alterações devem ser realizadas na fábrica para que esta opere com um menor consumo energético. Nestes estudos foi analisada a necessidade de importação de vapor HPII (High Pressure II) da Central Termoeléctrica e as situações em que esta pode ser minimizada. Foi conseguido através de optimizações,relativas ao caso base simulado, obter uma poupança de cerca de 0,73%, o que equivale a cerca de 1,1 M€/ano. Estudou-se ainda a possibilidade de integrar novos permutadores na secção de Baixas Temperaturas, também com o objectivo de minimizar a quantidade de vapor importada da Central. Introduzindo um permutador de multi-passagem conseguiu-se prever, referente ao caso base simulado, que este poderia gerar uma poupança de 0,90%, que corresponde a cerca de 1,37 M€/ano. Outra alteração possível seria substituir o nível de etileno refrigerante num dos permutadores de caixa e tubos da secção de Baixas Temperaturas, a qual apresentou uma poupança de 1,54% em relação ao caso base simulado, equivalente a 2,35 M€/ano, não necessitando esta última de investimento de equipamento.

The main purpose of this work is to develop an environment that allows HYSYS R chemical process simulator communication with sensors and actuators from a Foundation Fieldbus industrial network. The environment is considered a hybrid resource since it has a real portion (industrial network) and a simulated one (process) with all measurement and control signals also real. It is possible to reproduce different industrial process dynamics without being required any physical network modification, enabling simulation of some situations that exist in a real industrial environment. This feature testifies the environment flexibility. In this work, a distillation column is simulated through HYSYS R with all its variables measured and controlled by Foundation Fieldbus devices

A hidrodesnitrogenação catalítica é um processo utilizado para remover impurezas de nitrogênio em produtos derivados de petróleo e ocorre mediante o tratamento da carga com hidrogênio a temperatura e pressão elevadas em um reator do tipo tricled-bed. Para otimizar as operações nestes reatores, é necessário que se tenha informações sobre a cinética das várias reações de hidrodesnitrogenação. Entretanto, as equações das taxas das reações não estão disponíveis na literatura. Assim, o objetivo deste trabalho consiste em obter as equações das taxas das reações e os parâmetros cinéticos para a rede reacional dos compostos nitrogenados utilizando o modelo rigoroso de hidrodesnitrogenação do Aspen Hysys como base numérica para as simulações. Experimentos numéricos foram realizados em um reator diferencial no software Aspen Hysys para obter dados de concentração de reagentes e produtos a diferentes alimentações. Diferentes métodos foram utilizados, um método de regressão linear multivariável para obtenção dos coeficientes de regressão, um método de metamodelagem interpoladora estocástica, o Kriging e a otimização do metamodelo Kriging utilizando o método dos mínimos quadrados. Para testar as metodologias propostas, todas as etapas foram aplicadas para um sistema de duas reações simples, uma reversível e outra irreversível, em um reator PFR. Os resultados referentes ao método de regressão linear mostraram que a metodologia pode ser utilizada para estimar parâmetros cinéticos desde que se conheça a equação da taxa correspondente. A comparação entre os dois métodos do tipo Kriging propostos (convencional e otimizado) foi feita a partir de técnicas de análise estatísticas, como o coeficiente de determinação R² e análise de variância (ANOVA). O kriging otimizado mostrou uma melhor aderência aos dados quando comparado com o kriging convencional.
Catalytic hydrodenitrogenation is one process used to remove nitrogen impurities from refinery streams, and it occurs by reacting a given charge with hydrogen at high temperature and pressure in a trickled-bed reactor. In order to optimize the operation of such reactors one needs information about the kinetics of the various hydrodenitrogenation reactions. However, reaction rate expressions are not available in the open literature. Therefore, this work aims at obtaining the reaction rate expressions and parameters for the reaction network of nitrogen compounds using the rigorous hydrodenitrogenation model in Aspen Hysys as the numerical basis for simulations. A differential reactor to simulate the process for different feed streams generated data to estimate of concentration of reagent and products at different feed loads. Three different methods were used, a multivariable linear regression model to obtain the regression coefficients, a stochastic interpolator metamodeling, Kriging and an optimized Kriging with least square method. In a first step, two simple reactions rates were used to test the methodologies in a reactor PFR in Hysys, a reversible and an irreversible. The results showed that linear regression might be use to estimate parameters satisfactory only if you know the reaction rate expression. By using statistical analysis as determination coefficient R² and analyze of variance, ANOVA, it was possible to compare both Krigings (conventional and optimized). Optimized Kriging showed a better adherence to the data when compared to conventional kriging.

Elements of Chemical Process Engineering were used in this research to design and simulate two continuous transesterification processes for the production of biodiesel from palm oil, using the chemical simulator, HYSYS®. This design specified the operating conditions of all the equipment required for the continuous production of biodiesel using ethanol and methanol as alcohols. The palm oil was modeled as a mixture of the triglycerides that compose it in greater proportion, estimating the chemical properties of the substances that take part in the transesterification reaction, with group contributions and group interactions theories. Finally, the quality specifications for biodiesel obtained in both simulations were analyzed to verify the fulfillment of the properties required by ASTM (American Society for Testing and Materials) and EN (European Norms) standards.

Abstract:
Results of a system evaluation and lifecycle cost analysis are presented for a commercial-scale high-temperature electrolysis (HTE) central hydrogen production plant. The plant design relies on grid electricity to power the electrolysis process and system components, and industrial natural gas to provide process heat. The HYSYS process analysis software was used to evaluate the reference central plant design capable of producing 50,000 kg/day of hydrogen. The HYSYS software performs mass and energy balances across all components to allow optimized of the design using a detailed process flow sheet and realistic operating conditions specified the analyst. The lifecycle cost analysis was performed using the H2A analysis methodology developed by the Department of Energy (DOE) Hydrogen Program. This methodology utilizes Microsoft Excel spreadsheet analysis tools that require detailed plant performance information (obtained from HYSYS), along with financial and cost information to calculate lifecycle costs. The results of the lifecycle analyses indicate that for a 10% internal rate of return, a large central commercial-scale hydrogen production plant can produce 50,000 kg/day of hydrogen at an average cost of $2.68/kg. When the cost of carbon sequestration is taken into account, the average cost of hydrogen production increases by $0.40/kg to $3.08/kg.

Abstract:
A standard process for CO2 capture based on absorption in mono ethanolamine (MEA) has been simulated and cost estimated with an equilibrium-based model in Aspen HYSYSTM. The aim has been to calculate cost optimum process parameters and evaluate the possibility of automated cost optimization using a spreadsheet facility. An Excel spreadsheet is used for dimensioning and cost estimation of the specified process. New in this work is that Visual Basic for Application (VBA) was used to automatically update installation factors for next iteration based on cost calculations in previous iteration. The equipment cost was obtained from the Aspen In-plant Cost EstimatorTM, and an enhanced detailed factor (EDF) method was used to estimate the total investment cost. The optimum process was found as the process with minimum calculated total cost. The cost optimum process parameters for the standard process were calculated to 15 m absorber packing height, 9 °C minimum approach temperature and 2.2 m/s superficial gas velocity through the absorber. With this approach, iterative cost estimation and optimization of CO2 absorption and desorption processes can be performed automatically.
