From the standpoint of plant operations, the Chilled Ammonia Process has demonstrated stable operation over the expected operating range. The CAP process offers the flexibility and ability to follow daily and weekly changes in plant load requirements in the typical range of 30-100% without substantial impact on the process.As ammonia is a commonly and widely used chemical, the ammonia reagent in the CAP plant also lends itself to fewer permitting requirements, including any waste disposal issues that may arise. The by-product from the CAP facility is a liquid ammonium sulphate stream, which can be of commercial value as a fertilizer.The power consumption of CO2 compression represents normally a substantial part of the total power consumption for other CO2 capture technologies. Since CAP involves the production of a higher pressure CO2 product gas stream in the regenerator, it results in significantly lower capital and power costs for CO2 compression equipment.
