Bioprocess utilizing carbon dioxide and electrodeionization
Patent
·
OSTI ID:1531883
A method for producing succinic acid is provided, which comprises circulating a fermentation broth containing succinate ion through an electrodeionization apparatus. The apparatus comprises an anode; a cathode; a stacked ion-exchange assembly comprising a one or more oriented ion-exchange units between the anode and the cathode. Each ion-exchange unit comprises a porous ion-exchange resin wafer including an inlet and an outlet together are adapted to circulate a liquid reaction stream containing a carboxylate anion from a fermentor through the resin wafer; a flow-distributing gasket for circulating a product stream through a product reservoir; an anion exchange membrane for transporting at least a portion of the carboxylate anion to the product stream; and a bipolar ion-exchange membrane to direct protons toward the cathode and into the product stream and to direct hydroxyl ions toward the anode and into the reaction stream in the resin wafer of an adjacent ion-exchange unit.
