  • Method of use of a multi-stage reactor-separator with simultaneous product separation
    Patent number: 5141861
    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.

  • Immobilized cell reactor-separator with simultaneous product separation and methods for design and use thereof
    Patent number: 4665027
    Abstract: A novel immobilized cell reactor design is described capable of separating an inhibitory metabolite from a fermentation broth as it is formed. This reactor has the dual advantages of (1) speeding product inhibited reactions and (2) giving a concentrated product free of substrate and cells. The immobilized cell reactor separator (ICRS) can consist of two columns; in the first or `enriching` column stripping gas and broth move co-currently after which the liquid phase moves to the top of the second `stripping` column and moves counter currently to the stripping gas while the remaining substrate is converted to product. The use of this reactor in an ethanol from whey lactose fermentation system is also described.
