ABSTRACT:
Disclosed is a process for dewatering an organic compound other than a carboxylic acid using a simulated moving bed (SMB) containing a solid with different absorptivities for water and the organic compound. The organic compound is fed into the SMB as an aqueous solution and desorbed with a desorbent other than water. The process is particularly useful for dewatering organic compounds produced by fermentation, biomass extraction, biocatalytic, and enzymatic processes.
