Abstract

See full text

The present disclosure relates to a thermal coupling method for preparing ethylene by ethanol dehydration and device thereof. The device includes an ethanol dehydration reaction system, a quenching compression system, an alkaline washing system, a molecular sieve drying system and an ethylene purification and propylene refrigeration cycle system; ethanol dehydration reaction products in the ethanol dehydration reaction system serve as a heat source for preheating, vaporization and superheating of a raw material of ethanol; tower bottoms of an evaporation tower in the quenching compression system serve as a heat source for preheating of a feed stream of the evaporation tower and heating of an overhead gas of a quenching tower; products of ethylene in the alkaline washing system serve as a cold source for cooling of crude ethylene.
