| Abstract | Bioethanol production from lignocellulosic biomassis acombination of batch and continuous processes. Such processesmainly consist of pretreatmentto recoverthe highestpossible content of celluloseduring fermentationusing hydrolysis and yeast to convertcellulose into bioethanolwith purification to produce the required level of biofuel concentrate. This study aims to developa simulation modelfor producing bioethanol from oil palm trunks(OPTs)and empty fruit bunches(EFBs), involvingthe batch schedulingof pretreatment and fermentation to produce99.0%wt. bioethanolat 10,000 L/day. Furthermore, OPTsand EFBs offer the flexibility to change feedstockswhich also affectsthe schedule. In this study, Aspen Plus calculates the raw materials and utilities required using the Aspen Batch Process Developer (ABPD) and then schedulesthe batch operation. To produce bioethanol, the results indicatethat OPTsand EFBswith a ratioof1:1 should be fed 24,000 kg-OPTs/dayand 24,000 kg-EFBs/day to produce the required amount of bioethanol. The pretreatment section should be operated in two cycles and fed into a fermenter every 240 min. Moreover,to schedulethe fermentationprocess,ideally,15 parallel fermenters should be used toensure a continuous supply forpurification.Extractive distillation and pervaporation technologies are proposed in this study,consuming16.78 and 19.24 MJ/L, respectively, to produce bioethanol inthe targetedamount. |
