Abstract

DISCLOSED IS A METHOD OF REMOVING DIMETHYL ETHER FROM AN ETHYLENE AND/OR PROPYLENE CONTAINING STREAM. DIMETHYL ETHER IS REMOVED AT A LOW PRESSURE, PREFERABLY IN A DISTILLATION COLUMN (126).THE LOW PRESSURE SEPARATION HAS THE BENEFIT OF PROVIDING A RELATIVELY LOW TEMPERATURE SEPARATION, WHILE ALLOWING FOR RECOVERY OF A HIGHLY CONCENTRATED ETHYLENE AND/OR PROPYLENE STREAM.(FIG 1)
