Abstract:

When mixing in a tank is insufficient solid particles are known to form a concentration gradient along the height. The one-dimensional sedimentation dispersion model provides a relationship between mixing parameters and the solids concentration gradient. An investigation of the relationship between the solid mixing properties and the solids residence time distribution, as derived from the sedimentation dispersion model has been conducted. Experimental results show that the solids residence time distribution was a function of particle size and differed from that for the liquid phase. An

Abstract:

Bioreactors are used to carry out bioprocesses and are commonly used in e.g. biogas production and wastewater treatment. Two common hydraulic models of bioreactors are the continuous stirred tank reactor (CSTR) and the plug-flow reactor (PFR). In this paper, a differential equation system that describes the substrate, biomass and inert biomass in the bioreactors is presented. It is used in a steady-state analysis and design of CSTRs in series. Monod kinetics were used to describe the specific growth rate and the decay of biomass was included.

Abstract:

Global industrialization has continued an upwards trend, so is the global energy demand increasing. At the moment the major source of energy is fossil-based which leaves a huge and overwhelming carbon footprint which has a devastating effect on the environment. Hence, the quest for alternative cleaner sources of energy is gaining some tremendous interest. The conversion of waste to renewable energy proves to be economical and sustainable. However, the objective of this research work is to explore alternative and more efficient methods of digesting waste cooking oil into CH4 bearing in mind the

Abstract:

In this study, the performance of the Model Predictive Controller (MPC) algorithm is investigated in two different reaction systems. The first case is a saponification reaction system where ethyl acetate reacts with sodium hydroxide to produce sodium acetate and ethanol in a CSTR. In the reactor, temperature and sodium acetate concentration are controlled by manipulating the flow rates of ethyl acetate and cooling water. The model of the reactor is developed considering first principal models. The experiments are done to obtain steady state data from the reaction system and these are compared

However, the solubility of ferric ion is low at higher pH that it tends to precipitate, resulting in the formation of ferric ion precipitates. The formation of ferric ion precipitates in bio-hydrometallurgy decreases the leaching efficiency by trapping the leached metals in solution

Syftet med studien är att genom fem uppställda hypoteser undersöka om det finns något samband mellan omfattningen av företags CSR-kommunikation och variablerna: omsättning, segment (börsvärde), omsättning per anställd, branschtillhörighet, samt vilken typ utav CSR-kommunikation som används mest frekvent.

Abstract:

Problemformulering: Författarna har inte identifierat forskning om CSR-strategi utifrån ett avdelningsperspektiv. Kunskapsluckan studien vill undersöka är därför företagsavdelningars drivkrafter att arbeta med CSR, likheter och skillnader mellan avdelningars CSR-arbete och hur de samordnas. Syfte: Syftet med uppsatsen är att undersöka hur avdelningarnas CSR-arbete stödjer integreringen av företagets totala CSR-strategi. Frågeställning: Vilka drivkrafter bidrar till avdelningarnas arbete med CSR? Hur genomför respektive avdelning sitt CSR-arbete samt vilka likheter och skillnader finns det? Hur

Abstract:

Den svenska hotellbranschen går mot en utveckling av allt fler och större hotellkedjor. Genom sina stordriftsfördelar pressar hotellkedjorna ner priserna och standardiserar erbjudande vilket lett till att konkurrensmedlen har blivit färre. För att tilltala de viktiga företagskunderna är därför behovet stor av nya konkurrensmedel. Kunder ställer idag högre krav på att företag tar sitt ekonomiska, sociala och miljömässiga ansvarstagande, CSR, och desto större företaget är desto större är kraven. Dessa krav leder till att företagskunder ställer allt högre krav på sina leverantörer. Ett verktyg fö
