Title:
COMPACT HEAT ENGINES FOR WASTE HEAT RECOVERY
Document Type and Number:
WIPO Patent Application WO/2023/111776
Kind Code:
A1
Abstract:
A compact energy recovery system is described, which includes a heat exchanger that transfers heat from a waste heat source to a pre-heated high temperature compressed fluid while generating a high temperature fluid and a partially cooled waste heat stream. A high temperature fluid expander expands the high temperature fluid to generate a high temperature expanded fluid. A multi- stream heat exchanger simultaneously transfers heat from the high temperature expanded fluid and the partially cooled waste heat stream to a low temperature, high pressure fluid while generating a low temperature waste heat stream, low temperature expanded fluid and a high temperature compressed fluid. The low temperature expanded fluid is cooled in a heat exchanger and compressed using a pressure raising system to produce a low temperature, high pressure fluid. The low temperature, high pressure fluid is fed into the multi- stream heat exchanger to complete the cycle.
