Sour Water Stripping Fouling Troubleshooting and Prevention

In 2013, we made a concerted effort to focus on sour water stripping to improve our analytical, testing, simulation, and troubleshooting capability. This video covers the causes we have witnessed, how to identify the root cause, and how to prevent sour water stripper fouling from happening.
Amine Experts SWS System Fouling Investigation Service: Sour water can cause extreme fouling of the associated equipment and is also a very corrosive service. Unfortunately, many strippers require more frequent shutdowns than the rest of the refinery which can have a significant economic impact. Our fouling investigations are extremely rigorous and entail connecting a specialized in-situ filtration and coalescing test rig to the sour water feed to collect particulate and liquid hydrocarbon-based fouling precursors at operating conditions. This installation permits us to accurately analyze and then diagnose the root cause of the fouling. Fouling can also be exacerbated by several things: corrosion products, salt deposition, elemental sulphur, and polymerization. Through this process, fouling is either eliminated or a mitigation strategy is defined to restore the SWS unit’s runtime to fit normal turnaround schedules.
