Experimental and Theoretical Study of the Energy Savings from Wet Ethanol Production and Utilization

摘要: As a result of the energy crisis in recent decades, biofuels have gained importance as an option to diminish oil dependence automotive industry. Ethanol is one these for which demand around world has increased years. However, be used fuel, ethanol must dehydrated avoid problems actual engines, and this step high cost. To overcome drawback, some studies demonstrated use wet homogeneous charge compression ignition (HCCI) engines. In work, production ethanol, using conventional distillation, was studied rigorous simulation experimental tests distillation column. The analysis validation requirements obtain were achieved. results showed that can produced by column with small number stages low reflux ratios, savings. Also, indicated purities distilled (wet ethanol), ratios between required during process combustion low. This implies considered realistic HCCI
