A processing scheme and arrangement for enhanced olefin production involves cooling or treating an olefin cracking reactor effluent stream by contacting the olefin cracking reactor effluent stream with a quench oil stream in a single contact cooler contact zone to produce a cooled vapor stream and to form a heated quench oil stream. A pressure differential across the single contact cooler is less than about 3.5 kPa. The heated quench oil stream can be subsequently cooled and returned to the single contact cooler.
