Title: MODIFIED GOSWAMI CYCLE BASED CONVERSION OF GAS PROCESSING PLANT WASTE HEAT INTO POWER AND COOLING WITH FLEXIBILITY
Abstract:
A system includes a waste heat recovery heat exchanger configured to heat a heating fluid stream by exchange with a heat source in a crude oil associated gas processing plant; and a modified Goswami energy conversion system. The modified Goswami energy conversion system includes a first group of heat exchangers configured to heat a first portion of a working fluid by exchange with the heated heating fluid stream; and a second group of heat exchangers configured to heat a second portion of the working fluid. The modified Goswami energy conversion system includes a rectifier configured to receive the heated first and second portions of the working fluid and a third portion of the working fluid and to output an overhead discharge stream and a liquid stream, the third portion of the working fluid being at a lower temperature than the heated first and second portions of the working fluid. The modified Goswami energy conversion system includes a cooling subsystem including one or more cooling elements configured to cool a chilling fluid stream by exchange with the overhead discharge stream; and a turbine configured to generate power from the liquid stream of the working fluid.
