Abstract: The method combines different electrolyte solutions having the same solvent. The solution is successively compressed and vaporized at different temperatures and the vapor is successively absorbed by the second solution that exhibits higher negative deviation, at higher temperature. The absorption heat of each absorber is recovered by the next evaporator. The more evaporator-absorber pairs that are used the higher the temperature lift or the created pressure ratio. Finally the vapor returns to the first solution at high temperature. Electrolyte is dissolved and rejected from each solution to achieve total heat recovering and the very high efficiency of the cycle. Gas absorption is suggested instead of solvent vapor.
