Abstract:

In practice, distillation may be carried out by either of two methods. The first method is based on the production of vapor by boiling the liquid mixture to be separated and condensing the vapour without allowing any liquid to return to the still. Then, there is no reflux. The second method is based upon the return of part of the condensate to the still under such conditions that this returning liquid is brought into the intimate contact with the vapours on their way to the condenser. Either of these two methods may be conducted as a continuous or as a batch process, but the study of dynamics

Abstract:

The global fossil reserves are dwindling and there is need to find alternative sources of energy. With global warming in mind, some of the most commonly considered suitable alternatives include solar, wind, nuclear, geothermal and hydro energy. A common challenge with use of most alternative energy sources is ensuring continuity of supply, which necessitates the use of energy storage. Hydrogen has properties that make it attractive as an energy carrier. To efficiently store energy from alternative sources in hydrogen, several methods of hydrogen production are under study.

Accurate modeling of mixed solvent electrolyte systems is difficult and is not readily available in property modeling software such as Aspen Plus. Support for modeling these systems requires the knowledge and input of parameters specific to the compounds in question.

Abstract:

This project work reports steady state simulation results of a continuous stirred tank reactor (CSTR) system using Aspen-plus simulation. The reaction, investigated in this work was production of ethyl benzene using ethylene and benzene as the reactants. Ethyl benzene, being one of the important raw materials in production of several industrially important chemicals, is often produced alongside with diethyl benzene as an undesired side product. In our simulation, this particular aspect has been examined to maximize the conversion of ethyl benzene from its reactants. Here, we have studied the e

Abstract:

Bio fuels have been considered to be the viable alternatives and the supportive sources for the depleting fossil fuels under the objective of satisfying the energy demand. The work explored the possibility of biogas production in various operational scales. The present work can be categorized into two parts. In the first part, the work has surveyed various digester designs under operation and focused on the mixing and intermittent aeration that are not under light in the regular practice. The digester gas collector configuration that could promote the mixing and intermittent aeration was desig

Abstract:

Thermochemical processes for hydrogen production driven by nuclear energy are promising alternatives to existing technologies for large-scale commercial production of hydrogen, without dependence on fossil fuels. In the Copper-Chlorine (Cu-Cl) cycle, water is decomposed in a sequence of intermediate processes with a net input of water and heat, while hydrogen and oxygen gases are generated as the products. The Super Critical Water-cooled Reactor (SCWR) has been identified as a promising source of heat for these processes. In this thesis, the process analysis and simulation models are developed

Abstract:

Fluidized bed gasification is one of the potential sources for production of clean and eco-friendly fuel. With the gradual depletion of coal and petroleum resources biomass is being perceived as a self-sustainable source of energy production. It is cheap and readily available as well. ASPEN PLUS simulator is a strong tool for investigating the behavior of a process and it can be readily used to access various aspects like feasibility of an operation, effect of operating parameters on the performance of a gasifier. In this project work the effects of temperature, steam to biomass ratio, pressur

Abstract:

Yes<br>Process simulation of a single-step synthesis of DME based on CO2-enhanced gasification of rice straw was conducted using Aspen PlusTM. The process consists of gasification unit, heat recovery unit, gas purification unit, single-step DME synthesis, and DME separation unit. In the simulation, highly pure DME was produced by the control of CO2 concentration in syngas to a very low level prior to synthesis. A gasification system efficiency of 36.7% and CO2 emission of 1.31 kg/kg of DME were achieved. Bio-DME production based on CO2-enhanced gasification of biomass was found to be more cost

Abstract:

Yes<br>The biomass gasification process is widely accepted as a popular technology to produce fuel for the application in gas turbines and Organic Rankine Cycle (ORC). Chemical reactions of this process can be separated into three reaction zones: pyrolysis, combustion, and reduction. In this study, sensitivity analysis with respect to three input parameters (gasification temperature, equivalence ratio, and steam-to-biomass ratio) has been carried out to achieve energy self-sufficient conditions in a steam gasification process under the criteria that the carbon conversion efficiency must be mor
