Recovering chemical products from dilute fermentation broths
Resurgence of interest in the fermentation of renewable biomass to produce oxychemical feedstocks and specialty chemicals has suggested the corollary need for new energy-efficient processes to recover products from dilute aqueous broths. Of the commercially demonstrated processes, distillation appears most suitable for low boilers, while solvent extraction appears to be the method of choice for high boilers. A number of new approaches such as supercritical extraction, molecular sieve adsorption, and membrane separation hold promise for further development. In any event, the concomitant development of both new fermentation systems and recovery processes appears critical to the growth of a revitalized fermentation industry. 47 references, 14 figures, 5 tables.
