Title: METHOD AND APPARATUS FOR PRODUCING SOLVENTS BY FERMENTATION
Abstract:
The present invention relates to a method for producing products, advantageously solvents, by fermentation, advantageously multi-stage fermentation. The fermentation is complemented with pervaporation as in situ product recovery technology, combined with a multistage condensation of the permeate. The condensates are separately introduced in the downstream processing to recover the produced products, advantageously solvents. The method for producing products, advantageously solvents, by fermentation is simplified and has an overall improved energy efficiency, compared to methods described in the art. A related system and the use thereof is provided as well.
