Abstract: Bioethanol derived from lignocellulosic (Cellulose, Hemicellulose and Lignin) Empty Palm Fruit Bunch biomass is widely appreciated for renewable waste from the palm oil production process. In this research, a techno-economic analysis of such bioethanol production was carried out using Aspen Plus and Aspen Economic Analyzer for simulation and economic analysis based on the use of 47,000 kg Empty Fruit Bunch (EFB) biomass per day to produce 10,000 kg ethanol per day. This study focuses on 4 simulations, 1) Hot compressor water (HCW) with extractive distillation, 2) Hot compressor water (HCW) with Molecular sieves distillation, 3) Steam explosion with extractive distillation and 4) Steam explosion with Molecular sieves distillation. Either Hot compressor water or Steam explosion was employed in the pre-treatment process due to its environmentally friendly properties. Comparison of the extractive distillation and Molecular sieves in the purification process for get the ethanol more than 99% was performed. Model input was based on data recently obtained in the laboratory. The results from the simulation and the economic analyst revealed that the plant used the pre-treatment with Hot compressor water (HCW) and Molecular sieves in purification process use least of total capital investment (TCI) and total production cost (TPC). In terms of Net Present Value (NPV), this simulation showed a positive value, meaning suitable for investment. Although the payback period was 5 years, an analysis was also made regarding possible profit. This study was the waste-recovery for ethanol production, that can be used for renewable energy and clarified as environmentally friendly properties.
