Due to the azeotrope of ethanol and water, the purity of ethanol can reach up to 95wt% by ordinary distillation.
In order to break the azeotrope, the current mainstream process is to use rectification + membrane separation or rectification + molecular sieve technology.
Shanghai Ruihao mainly provides process systems and equipment for the entire ethanol dehydration process
