In a typical LPG recovery plant, heat is needed for an amine reboiler, as well as additional horsepower to compress residue gas to pipeline pressure. With the design of a power recovery package, waste heat from turbine exhaust can be utilized to supplement the necessary horsepower and to fulfill the amine reboiler duty requirement. This reduces the number of turbines needed to achieve the compression and hence the operating cost. This paper discusses the design of such a system using propane as the power fluid, both from the application point of view as a pure heat medium system, and a power recovery system.
