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.

Fouling Control Nalco Champion fouling control programs use dispersants, scale inhibitors and surface cleaning products to reduce the deposition of organics, calcium salts and corrosion byproducts. Controlling fouling in the SWS helps ensure stripping efficiency; in extreme cases, poor SWS operation can impact the whole refinery.
Corrosion Control The tower and the overhead sections are exposed to high levels of H2S, CO2 and ammonia and can experience high rates of bisulphide and carbon dioxide corrosion. In some cases, corrosion risks are compounded by high levels of cyanides from upstream units that concentrate in the overhead. Nalco Champion water-soluble filming corrosion inhibitors coupled with process optimization can significantly reduce the risks of corrosion, helping to maintain stripping efficiency and asset integrity.
