Abstract
An absorption system and process that operates around a crystallization curve of a solution with a crystallization limitation. At least a portion of dilute solution discharged from an absorber is mixed with relatively strong absorbent flowing from a generator. The mixture is controlled so that the cycle steps around the crystallization curve of the solution. One preferred solution is water-lithium bromide. One preferred strong/weak concentration of the water-lithium bromide solution is approximately 66%/62%. A preferred operating concentration bandwith of the water-lithium bromide solution is approximately 4%. A solution heat exchanger independent from the absorber is positioned upstream from the absorber and is used to transfer heat from the mixture of the relatively strong absorbent and the diluted solution to either a heat rejection mechanism or a heat collection mechanism. Two preferred absorber mechanisms include a spray absorber and a rotating disk distribution absorber.
