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.
An absorption system that operates around a crystallization curve of a solution with a crystallization limitation, the system comprising:
In an absorption system operating with a solution having a crystallization curve, wherein the system has a generator, a condensor downstream from the generator, an evaporator downstream from the condensor, an absorber downstream with respect to refrigerant flow from the evaporator, and a first heat exchanger transferring heat from an absorbent discharged from the generator to the solution discharged from the absorber, the improvement comprising:
An absorption process using a spray absorber and operating around a crystallization curve of a solution with a crystallization limitation, including the steps of:
In an absorption process operating with a solution having a crystallization curve, wherein the solution is heated to separate an absorbent of the solution from a refrigerant of the solution, the separated refrigerant is condensed, the condensed refrigerant is evaporated, the evaporated refrigerant is absorbed into the absorbent to form the solution in a dilute state, and heat is transferred from the separated absorbent to the diluted solution, the improvement including:
