METHOD FOR RECOVERING ETHYLENE FROM A PURGE GAS FROM A FACILITY FOR THE PRODUCTION OF ETHYLENE OXIDE.

摘要

THE PRESENT INVENTION REFERS TO A METHOD FOR THE ECONOMIC RECOVERY OF ETHYLENE FROM GAS RELEASED BY AN ETHYLENE-CONTAINING PLANT FOR THE PRODUCTION OF ETHYLENE OXIDE, WHERE ETHYLENE IS SEPARATED FROM SATURATED HYDROCARBONS AND ETHANE AND ETHANE RECOVER EFFICIENTLY. PURSUANT TO THIS METHOD, THE RELEASED GAS IS CONTACTED WITH A MOLECULAR SIEVE CARBON TO SELECTIVELY ABSORB ETHYLENE WITHOUT SUBSTANTIALLY ABSORBING THE OXYGEN PRESENT IN THE RELEASED GAS, THEN THE ETHYLENE IS ABSORBED AND RELEASED.
