Abstract:
1. A method for waste heat recovery, comprising the following steps: a) performing heat exchange in a regenerator between an anhydrous absorption liquid comprising an absorbent and an absorbed agent from an absorber and a heating working medium from a low temperature heat source to form the absorbent and the superheated high pressure absorbed agent; b) conveying the superheated high pressure absorbed agent generated in Step a) through a dryer, then conveying the dried superheated high pressure absorbed agent to a turbine to generate power or to a heat exchange device to provide a heat source; and c) contacting the absorbent from Step a) with the absorbed agent discharged from the turbine or the heat exchange device of Step b) in the absorber to form the anhydrous absorption liquid.
