The object of this study is to determine the feasibility and cost of installing a power recovery system in an existing gas processing plant. The power generated by the system is to be used to drive a residue gas compressor, a refrigeration compressor and the heat medium circulating pump, each having its own expander driver. For this purpose the heat from the exhaust of a number of gas turbines is to be combined to provide a total 75 MM Btu/hr. heat energy. Because of safety reasons, Freon 12 has been chosen for the working fluid. The condensing media is water at a design temperature of 80 degrees F. The process conditions for the cycle and the duties of the major equipments are described.
