Fouling in an acrylonitrile (AN) production facility is a common challenge for producers. Both AN and hydrogen cyanide (HCN) are reactive monomers that can polymerize under production conditions, resulting in process fouling. The most prevalent treatment for acrylonitrile polymer fouling is hydroquinone (HQ), which is only partially effective. The breakthrough Nalco Champion high performance inhibitor technology challenges the existing industry standard for polymer control.

Nalco Champion has more experience with acrylonitrile unit fouling control than any other company in the world. Through years of research and development efforts, Nalco Champion has developed and proudly offers the industry’s best in fouling control technology:
Patented multifunctional polymer inhibitor technology The Nalco Champion Acryl-ex™ inhibitor package represents a major improvement over standard inhibitors. Nalco Champion Acryl-ex™ offers more effective polymer inhibition and ease of use when compared with commodity alternatives. The effectiveness of the Nalco Champion technology is well documented by major AN producers.
Dispersants specially designed for acrylonitrile processes Nalco Champion dispersant technology for acrylonitrile improves fouling control in the recovery section of the process, where performance is limited with an inhibitor alone.
Antifoam Nalco Champion antifoams for the acrylonitrile process are more effective than commodity offerings at lower injection rates.
