Abstract
A method provides for waste heat power generation or heat recovery and for a driving power with an absorption process using low grade heat sources. An apparatus also provides for such waste heat recovery in absorption process and to the used vapor-salt working fluid. A low temperature heat source is used as a heating working medium to heat in a regenerator by heat exchange the absorption liquid working fluid from the absorber and consisting of a salt absorbent and ammonia or carbon dioxide as an absorbed agent to form the absorbent and the superheated high pressure absorbed agent. The superheated and vaporized absorbed agent enters into a turbine to provide energy and generate power via turbine expansion step. After heat release, the resultant low pressure absorbed agent is discharged from the turbine and returns to the absorption step and contacts with the absorbent from the regeneration step to form the absorption liquid which can enter into the next thermodynamic cycle process.
