摘要

P PROCESS FOR RECOVERING, WITH A QUASI-CRITICAL OR SUPER-CRITICAL FLUID, THE ETHYLENE OXIDE FROM AQUEOUS SOLUTIONS. / P P ON SENDING AQUEOUS SOLUTION RICH INTO ETHYLENE OXIDE (OBTAINED, FOR EXAMPLE BY CATALYTIC OXIDATION OF ETHYLENE) TO A COLUMN 32 FOR CONTACT WITH CARBON DIOXIDE IN THE QUASI CRITIC OR SUPERCRITICAL STATE, TO SELECTIVELY REMOVE ETHYLENE OXIDE SOME WATER. The extended solution is recycled to an absorber and the ethylene oxide dioxyoxide 48 recovered from the ethylene oxide dioxoid system 38, after eventual relaxation 39, in a separation column 40, or by a similar device. / P
