Abstract

The study aimed to modify and optimize the UPLB-AMD Fuel-Grade Ethanol Distiller. The boiler was insulated in an attempt to minimize heat loss. The experiment followed a 3x2 full factorial design and the optimization process was implemented using response surface methodology. Results revealed that the insulator, composed of clay, rice hull, rice straw and water, was effective in reducing the heat loss of the boiler which translated to a lower fuel consumption of the distiller. The combined effects of cooling water flow rate and heat rate significantly (<0.05) affected the performance of the distiller in terms of alcohol content, alcohol recovery and energy ratio. The predictor equations revealed that operating the distiller at optimum cooling water flow rate (0.0069L/s) and heat rate (21570kJ/h) will give 84.7% alcohol content, 96.0% alcohol recovery and 0.82 energy ratio at 55% desirability.
