Sour Water Stripper Types and Applications

Sour water strippers are common in gas processing facilities, sulfur recovery units, wellhead facilities, and refinery applications. Understanding the variables allows engineers to better optimize the initial design and operation. Heretofore they have been designed using equilibrium stages. However, tray efficiencies have remained obscure with quoted values anywhere from 15% to 45%, a factor of three range.This paper reviews options for sour water stripper configuration. Options investigated include: single or double column for increased product purity
