In this study calculation over material and energy balances for bio-refinery product upgrading using membrane filtration (MF, UF, and RO), distillation, and ion-exchanger has been performed. Tests have been made with UF filtration in a pilot plant, separation tests made at lab with ion-exchanger and simulation using ASPEN plus simulator for distillation. Rough economic analysis has been made for the different solutions/techniques.
