Amine units remove acid gases, such as H2S. Their good operation is critical to optimum product quality, environmental compliance and the overall reliability of the refinery. Amine unit corrosion and foaming problems can cause refinery-wide rate reductions or even shutdowns, severely impacting the Total Cost of Operation (TCO). Nalco Champion provides corrosion and foaming control programs to help refiners protect their amine units and TCO.

Corrosion Control In conjunction with good monitoring, the Nalco Champion Intercept programme can reduce or eliminate corrosion and the resultant fouling and foaming. This, in turn, helps improve amine unit reliability and efficiency, extend run lengths, increase throughput and maximise energy efficiency. The overall result is a reduction in the refinery's TCO and a significant improvement in Return on Investment (ROI).
Foam Control Foaming in an amine unit can reduce adsorption and/or stripping efficiencies and compromise the optimum performance of the unit. Foaming is typically a symptom of other significant process problems such as corrosion, hydrocarbon contamination and other upstream influences. Nalco Champion antifoams are used to address immediate operational issues while the root causes are addressed, allowing the unit to maintain throughput and operational efficiencies. Antifoams are used on a continuous or intermittent basis and do not interfere with unit operations.
