Abstract
This invention pertains to separating an olefin stream into at least two olefin streams. The olefin stream that is to be separated is low in diene composition, which allows the olefin stream to be compressed at a relatively high temperature without causing fouling problems in the compressor system. The invention is particularly relevant to separating olefins obtained from an oxygen to olefins unit.
