摘要

To recover, with the aid of a fluid in the state almost - critical or super - critical, the oxide of ethylene, of aqueous solutions. / p & & p & it sends an aqueous solution 30 which is rich in ethylene oxide (for example obtained by catalytic oxidation of the ethylene) to a column 32 in contact with the carbon dioxide is the almost - critical or super - critical, in order to remove selectively of ethylene oxide water. 36 The depleted solution is recycled towards an absorber and recovered of ethylene oxide, 48 of the system of carboneoxyde of ethylene 38, after relaxation any 39, in a column separationdistillation 40, or by a similar device.
