摘要
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. The system includes a modified Goswami cycle energy conversion system including 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 cycle energy conversion system includes a separator configured to receive the heated first and second portions of the working fluid and to output a vapor stream of the working fluid and a liquid stream of the working fluid; a first turbine and a generator are configured to generate power by expansion of a first portion of the vapor stream of the working fluid; a cooling subsystem including one or more cooling elements configured to cool a chilling fluid stream by exchange with a cooled second portion of the vapor stream of the working fluid; and a second turbine configured to generate power from the liquid stream of the working fluid.
