Abstract
Systems and methods are provided herein for cooling an olefin cracking reactor effluent stream. One provided method includes reacting a hydrocarbon feedstock including C+ olefins in an olefin cracking reactor to produce an olefin cracking reactor effluent stream, providing the olefin cracking reactor effluent stream to an inlet of a contact cooler, contacting the olefin cracking reactor effluent stream with a first quench liquid in a first contact zone in the contact cooler to produce a first bottoms stream and an intermediate vapor stream, contacting the intermediate vapor stream with a second quench liquid in a second contact zone in the contact cooler to produce a second bottoms stream and a cooled vapor stream, and removing the cooled vapor stream from an outlet of the contact cooler. The method can also include cooling the first bottoms stream to provide a cooled first bottoms stream, and cooling the second bottoms stream to provide a cooled second bottoms stream.
