Techno-economic analysis of bioethanol production from lignocellulosic residues: a process simulation approach

The present work reports the technical analysis of bioethanol production from lignocellulosic residues like empty fruit brunches, rice husks & sugar cane bagasse. The ethanol production was figured utilizing aspen plus. The composition of the three feedstocks i.e empty fruit brunches, rice husks and sugarcane baggase were required for simulation which was collected from the literature study and web. This process of producing bioethanol from lignocellulosic residues is more economical than producing bioethanol from maize or sugar cane. Among the three lignocellulosic residues considered Rice husk and Empty fruit brunches are cheaper compared to sugarcane baggase and have high yield value of ethanol i.e 0.52 and 0.38 respectively. However the sugarcane baggase are comparatively costlier and have low yield value of ethanol. Due to their abundant availability and cheaper purchase price the lignocellulosic residues are more economical when compared to the conventional way of producing ethanol
