Green Oil Removal From Ethylene Plants

摘要

A method may comprise: feeding a backend deethanizer overhead stream comprising ethylene, ethane, and acetylene to a hydrogenation reactor; hydrogenating at least a portion of the acetylene in the backend deethanizer overhead stream to form a reactor effluent stream comprising ethylene, ethane, and green oil; feeding the reactor effluent stream to a gas/liquid coalescer; and removing at least a portion of the green oil from the reactor effluent stream to produce a cleaned effluent stream.
