Abstract
Molecular sieve membrane separation-distillation coupling process is utilized to purify ethanol,which is by-product from coal to ethylene glycol process.Based on this process,a plant is built to purity 4 000 tons per year of by-product ethanol,and ethanol product reaches the industrial grade A standard.The economic analysis on the process shows that the annual profit exceeds RMB 6.5 million,which sets up a demonstration for the promotion of the process in the coal-to-ethylene glycol industry and the realization of energy saving and efficiency enhancing.
