Numerical Simulation of ethanol production from molasses using thermos tolerant kluyeromyces Marxian’s

Abstract

Due to development of mathematical modeling in the field of chemical engineering there is need to explain each process using simulation techniques. Ethanol production from molasses through fermentation is a well-known processes, but some areas need to be researched. Numerical simulation was carried out to solve the Monod kinetics Model. On the basis of experimental results model was used to compare the results between them. In this research work numerical simulation is used to solve mathematical model of microbial growth and ethanol production using Kluyeromyces Marxian’s as a yeast. The experimental and model results are comparably same because the optimal results of ethanol production  occurs at pH 5.5, oxygen flow rate 0.1 vvm/l, agitation intensity 300 rpm and temperature 40 ^oC. Maximum ethanol production was obtained at 76 g/l through numerical simulation comparably same with experimental results at 76 g/l. This shows that we can use model to predict the next iteration with the help of numerical technique. Experimental data point and model results give accuracy and similarity up to 90 % which is comparably same.
