Abstract
The present invention is a process for removing oxygenated contaminants from an ethylene stream comprising: a) providing a dried ethylene stream (A) comprising essentially ethylene, up to 1 w % oxygenates, ethane, CO, CO2, H2, CH4 and C3+ hydrocarbons, b) sending said stream (A) to a C2 splitter/deethanizer to produce a bottom stream comprising essentially ethane, oxygenates and C3+ hydrocarbons, an overhead comprising the remaining components, c) sending said overhead to a fixed bed CO2 adsorption zone to recover a stream essentially free of CO2, d) sending said stream essentially free of CO2 to a demethanizer/CO stripper to recover an overhead comprising H2, CH4 and CO, liquid ethylene at the bottoms. In another embodiment the CO2 removal step can be made on the recovered ethylene.
