  Separations account for 60%-80% of the processing costs of most mature chemical processes.Membrane based separations offer several advantages over conventional technology such as lower energy costs and easy scale up.This technology option was explored as a promising method for removal of acetic acid,sulfuric acid, furfural, HMF and other toxic compounds from dilute acid pretreated biomass hydrolysates.The primary objective was to remove and recover acetic acid, a potent inhibitor of fermentative microorganisms.
