| Abstract: | The natural gas liquid(NGL) cryogenic separation plant was compartmentalized into six subsystems by the NGL technology flow trait.The model of exergy analysis for the NGL cryogenic separation plant was represented,and the assessment rules and count formulae of exergy analysis for the NGL plant were given.By using the actually measured operational data,the exergy on the operational working conditions of oilfield NGL system was analyzed.The limitation of the energy usage was found.Based on the calculation results,some proposals to improve the operational efficiency were raised. |

| Keywords: | NGL plant three-box models exergy analysis energy-saving lowering consumption |
