Separation of ethanol from ethanol-water mixture and fermented sweet sorghum juice using pervaporation membrane reactor

► Flux and selectivity are significantly affected in sweet sorghum fermentation broth. ► Ethanol flux is affected to a greater extent than water in the fermentation broth. ► Pervaporation performances in fermentation broth are dependent on operating time. ► Pervaporation performances in binary ethanol-water mixtures are time-independent.
