KINERJA DESTILATOR BERTINGKAT PADA DESTILASI DENGAN FILTER ISIAN KOLOM FRAKSI PIPA ALUMUNIUM

Abstract

Energy needs keep increasing is not followed by sufficient fuel supply. It is a must for energy supply in the future to develop renewable alternative and green energy. One of alternative energy is biofuel especially bioethanol. Indonesia has richness and diversity potential in biomass that can be converted into bioethanol. In bioethanol production, fermentation and distillation technique are needed for both quality and quantity optimum yield. This research�s aim is raising fractional distillation performance using 6, 8 and 9 mm raschig ring filter�s diameters filled at half or full level capacity. The performance parameter that will be observed and analyzed are ethanol volume, ethanol percentage, optimum time of distillation, effective time, residue of bioethanol percentage from fractional pipe, distillation�s ratio and ethanol pure volume per kilogram of cassava. This research produced for every 2000 ml beer bioethanol highest volume 117,67 ml in 9 mm ring with half filling, highest ethanol percentage 96,82 % in 6 mm ring with full filling, the fastest distillation time 33,83 minutes in 6 mm with full filling, the minimum effective time 0,53 min/ml in 9 mm ring with full filling, the highest distillation ratio 5,88 % in 9 mm ring with half filling and the highest ethanol pure volume per kilogram cassava 193,07 ml/kg in 9 mm with half filling. The best variation is the use of 9 mm diameter ring with full filling
