Quench exchange with extended surface on process side

摘要

A quench exchanger and quench exchanger tube with increased heat transfer area on the process side of the tube are provided. The exchanger provides increased heat transfer efficiency relative to a fixed tube length and at the same time eliminates stagnant and low velocity areas as well as recirculation eddies. The tubes incorporate a fin profile on the process side of the tube with alternating concave and convex surfaces. Additionally, the fins are preferably aligned with the tube center line as opposed to being twisted or spiraled.
