Absorption heat pumping (AHP) offers a highly economic and widely applicable avenue to process heat integration and heat recovery in natural gas liquid (NGL) fractionation plants. Economically priced equipment is now available for any required capacity rating. Installations are increasing. In conventional heat pumping, heat at a low temperature is supplied to an evaporator, causing a liquid to boil at low pressure. This low pressure vapor is compressed. The high pressure vapor condenses, giving up latent heat at a high temperature. The difference between the heat supply temperature and heat delivery temperature is the ''lift'' furnished by the heat pump. Existing NGL fractionation plants offer highly economic opportunities for retrofit AHP applications. Designers of new plants can exploit AHP technology to further economic advantage.
