The main processing steps of an organosolv process have been examined and simulated in more detail in prior literature and patents. For example, present an in-depth study on the ethanol organosolv process for wood chips considering fractionation of all products, additional washing stages, solvent recovery, heat integration and furfural separation. presented an even more detailed ASPEN Plus process simulation of the ethanol organosolv process for wood chips, in the wider context of bioethanol production, including a boiler for utilities. Therefore, processing steps for the simulation were based on ref 42, key process parameters defined in Table , and performance variables defined in Table . All utilities employed during the simulation follow heuristics given by refs 46 and 47. Table and Figure to 7 outline the main stages and steps of the organosolv process. Further references for individual stages are given in Table .
