Abstract:
1. A process for cooling an olefin cracking reactor effluent stream, the process comprising: reacting a hydrocarbon feedstock including C 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; cooling the first bottoms stream to provide a cooled first bottoms 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; cooling the second bottoms stream to provide a cooled second bottoms stream; removing the cooled vapor stream from an outlet of the contact cooler; and passing the cooled vapor stream through a mesh blanket before removing the cooled vapor stream from the contact cooler; wherein the first quench liquid and the second quench liquid each comprise at least one C
