Whether the aim is to minimize ethanol loss or reduce ethanol (VOC) emissions, a dedicated Ethanol Recovery System (ERS) can extract up to 95 % of ethanol entrained in vented raw fermentation gas. Besides, the ERS can concentrate the captured ethanol up to 12% v/v thus making it possible to feed scrubber bottoms to distillation.
