摘要

Abstract

For improving cold energy utilization of liquefied natural gas(LNG) and power generation of CO2 near-zero emission power cycle and reducing energy consumption of CO2 emission reduction

the exergy analysis of LNG cold energy utilization in CO2 near-zero emission power cycle was performed.A natural gas Rankine cycle with integrated CO2 near-zero emission power cycle was proposed.While maintaining the necessary supply of cold energy in pre-cooling and liquefaction of CO2

the deep cryogenic exergy of LNG in CO2 near-zero emission power cycle was converted to power by the natural gas Rankine cycle.The results showed that with the integration of the two above-mentioned power cycles

the exergy efficiency of LNG cold energy utilization could be increased from 34.9% to 55.7%

and the exergy efficiency of the entire integrated power cycle reached 57.9%.Meanwhile

the influences of some parameters of the natural gas Rankine cycle on power generation efficiency were analyzed.
