Energy Analysis of Biodiesel Production From Waste Groundnut Oil

The objective of the study was to carry out energy analysis of biodiesel production from Waste groundnut oil (WGO). 13 experimental runs were designed by Minitab software 16 to carried out the trans-esterification of WGO which involved the variation of catalyst concentration and methanol/oil mole ratio. Total Input energy and output energy of the process were determined to obtain the energy efficiency of the process. The results of the research gavehighest biodiesel yield of 92 % at the methanol/oil mole ratio of 7 and catalyst concentration of 0.7 wt/wt % Oil. The calculated input energy and output energy of 124.51MJ/Land 98.47 MJ/L respectively were obtained. The energy efficiency obtained from the biodiesel production was 0.72. The net energy of -35.04 MJ while the energy productivity of 0.08 kg.MJwas arrived at. Further research work on how to reduce input energy during biodiesel production needs to be carried out
