An open Rankine cycle heat pump that utilizes a multistage compressor having interstage desuperheating wherein process fluid in the form of water drawn from a waste heat producing process is used as the working fluid in the heat pump thereby eliminating the need for heat exchangers at the conventional evaporator and condensor locations. Heated return water drawn from the process is flashed to a vapor and the vapors passed through the compressor to provide thermal energy that is used in compatible process related equipment.

The method of recovering energy from an industrial process containing a heated waste fluid that includes the steps of: removing a portion of said heated waste fluid from the high temperature side of said process; flashing at least a portion of the removed heated waste fluid to a vapor; passing said vapor in series through a multistage compressor wherein the vapor is superheated within each stage; desuperheating the vapor leaving each compressor stage to a dry saturated state by spraying a liquid coolant into said vapor; and employing the vapor leaving the last stage of compression to provide thermal energy to compatible process related equipment.
