Abstract

A fuel-grade ethanol distiller was tested to determine its performance characteristics. Three heat rates (Heat Rate 1 (HR 1)-18764KJ.hr, Heat Rate (HR 2)-22555KJ/hr and Heat Rate (HR 3)-29464KJ/hr) were used to Know alcohol recovery, heat loss, performance of main parts and energy efficiency of the distillerEvaluation of the distilling apparatus proved that it could produce an average ethanol recovery of 29.74% (1.50L) for HR 1, 64.65% (3.26L) for HR 2 and 82.07% (4.16) for HR 3 from 50-Liter of 10% water- ethanol. mixture in the boiler. The largest amount of heat loss (57.69% over-all average) was due to the boiler due to absence of insulation. Heat losses were also due to the gas burner used which produced incomplete combustion. Higher heat rate performed well in terms of volume of distillate but the quality of distillate decreased (96.27%, 95.14% and 89.75% FOR HR 1, HR 2 and HR 3, respectively). Lastly, the energy efficiency of the apparatus in terms of energy consumption and energy obtained from the recovered were 23.58% for HI, 45.99% for HR2 and 62.84% for H3. Although low in energy efficiency, the apparatus can produce high quality alcohol with 90%-96% by volume which can already be used as fuel.
