This paper discusses the use of a non-phosphorous corrosion inhibitor program in alkaline conditions. Eliminating one of the sources of phosphate allows for better performance of heat exchanger tubes as evidenced by lower approach temperatures. In addition, utilizing a non-phosphorous corrosion treatment program extended the exchangers’ cycle on turnaround even for heat exchangers that are ran with lower water velocity.
