Sour Water Stripper
Sour waters produced by FCCU's, cokers, hydrotreaters and other units are fed to a sour water stripper (SWS). The SWS removes H2S and ammonia to make the water fit for reuse in the refinery. SWS tower fouling and corrosion are common operational problems that compromise asset integrity. Nalco Champion provides products and services designed to meet the challenges presented by SWS operations.
