Procedure to concentrate a diluted aqueous solution of ethylene deoxido

摘要

Improved process and Installation for concentrating diluted aqueous solution of ethylene oxide.Comprising: (a) The Desorber in diluted aqueous solution of ethylene oxide which is between 70jc and 100jc with steam in a distillation column and a pressure between 2 and 6 bars, to withdraw a Flow of water at the bottom of the distillation column and (b) The corrient decompress And water pressure between 0.4 and 1.5 bars.To form a gas stream is introduced into the distillation column as Fluid ethylene oxide Desorption. Consists of: an Absorption column (1); two systems of direct Exchange (2, 3); a Decompression System (4) and (5) a system that allows the return to the vapour column (4).
