Coordinated phosphate program
WebCoordinated phosphate treatment (CPT) or captive alkalinity program was first introduced by Purcell and Whirl [27] fulfilled in high pressure boilers operating at the range of 1000-2000 PSI. Four basic types of cycle chemistry programs are described by EPRI, ASME, the International Association for the Properties of Steam and Water, and other entities. They are phosphate treatment, caustic treatment, all-volatile treatment, and oxygenated treatment programs.
