Simulation of Ethanol Production by Fermentation of Molasses

Ethanol is a renewable resource of energy and is potentially cleaner alternative to fossil fuels. Production of ethanol is growing day by day at a great extent for its versatile application and demand. During recent years, production of ethanol by fermentation on a large scale has been of considerable interest to meet to increased demand. Fermentation is a biological process in which sugars such as glucose, fructose, and sucrose are converted into cellular energy and thereby produce ethanol and carbon dioxide as metabolic waste products. It has long been recognized that molasses from sugar-cane or sugar provide suitable substrates for ethanol production. Production of ethanol by fermentation of molasses is simulated by Simulation software Aspen Hysys 7.1 to investigate the effect of few important parameters like fermentation temperature, pressure that effect the production of ethanol and to optimize those parameters. The present investigation has demonstrated the trend of changing production by changing of those parameters.
