The non-condensable gases taken from the fractionator overhead systems of CDU’s, FCCU’s and delayed cokers are further separated and concentrated in the gas processing unit by a series of compression, cooling, adsorption and stripping steps. Problems caused by fouling and corrosion in these units can severely impact throughput rates, equipment efficiency and unit reliability, increasing the total cost of operation. Nalco Champion solutions mitigate these problems.

Fouling Control Fouling and pressure drop problems can be experienced in several locations of the gas separations unit, including compressors, towers and reboilers. Nalco Champion antifoulant technologies control fouling where corrosion products and organic foulants are present. These programs will increase unit run-lengths, thus reducing downtime and maintenance and cleaning costs.
Corrosion Control Our corrosion control programs effectively address corrosion in the towers and overhead sections of the gas separations unit. By mitigating corrosion the refinery can extend run-lengths, reduce maintenance costs and unscheduled downtime, and improve operational safety.
