摘要

PROCEDURE FOR RECOVERING ETHYLENE FROM RECIRCULATION CURRENTS IN ETHYLENE OXIDE AND ETHYLENE OXIDATION PRODUCTION FACILITIES WITH MOLECULAR OXYGEN. A FORKED CURRENT IS SEPARATED FROM THE RECIRCULATION CURRENT, TO WHICH A REDUCING AGENT, AS FOR AN EXAMPLE OF HYDROGEN, IS INCORPORATED. THE MIXTURE IS REACTIONED SO THAT THE SELECTIVE OXIDATION OF REDUCING AGENTS IS PRODUCED WITHOUT AFFECTING THE OIL CONTAINED IN THE MIXTURE. THE TEMPERATURE AT WHICH THE OXIDATION IS CARRIED OUT IS FROM 50 TO 350 DEGREES DEGREE AND THE PRESSURE INCLUDED BETWEEN 1 AND 30 ATMOSPHERES. THE CATALYST USED IS CUPIFERA BASED. THE GASES FROM THE OXIDATION REACTION ARE SUBJECT TO A CO2 ELIMINATION OPERATION, WHICH OBTAINS A CURRENT OF HYDROCARBONS FROM WHICH IT IS POSSIBLE TO RECOVER ETHYLENE AND/OR OTHER USED HYDROCARBONS.
