ABSTRACT:
A multi-stage reactor-separator for the fermentative production of volatile inhibitory products from non-volatile substrate includes a stirred tank reactor and a packed or tray-type gas-liquid contacting column separator. Each reactor and separator form a stage and a plurality of stages may be stacked into a tower, or otherwise placed to operate consecutively, forming a reactor-separator in which stages having gas flowing cocurrent to the liquid flow in the separator portion form an enriching section, and stages having gas flowing countercurrent to the liquid flow in the separator portion form a stripping section. In a method of using the reactor-separator, a volatile fermentation product is produced and simultaneously separated into a gas phase.
