Paper Title:
Study on a New High Efficiency Energy-Conservation Multi-Effects Bio-Ethanol Distillation Technology
  Abstract

A new four column multi-effects distillation technology for the production of edible alcohol is simulated and optimized by AspenPlus simulation software on the basis of energy conservation technique of multi-effects distillation. The optimized technical parameters are summed up as follows: the theoretical number of trays and top pressure of the beer column, aldehyde removing column, refining column 1 and refining column 2 are 17, 40, 62, 50 and 0.4 atm, 0.4atm, 1.9 atm, 6.0 atm respectively. Only the refining column 2 needs extra heat source, the calculated saturated steam (7 atm) consumption is 1.1t/t edible alcohol product; ethanol content in product edible alcohol is 95.6%(v/v), meets the GB10343-2002 high grade. The yield of the ethanol product is higher than 95%.
