Traditionally, Sour Water Strippers (SWS) have been designed using ideal stage techniques and stage efficiencies. Stage efficiency values between 15 to 45% have been employed in the industry. With such a wide range, it becomes difficult for the engineer to trust the design results and many units end up being grossly over-designed.
This webinar will discuss the various sources of sour water in refineries, the underlying chemistry between NH3 and acid gases that drives the process.
Understand SWS chemistry basics, correct approaches to modelling.
Demonstrate a case study with ProTreat® to simulate 1- and 2-stage SWS units using mass transfer rate-based model.
