摘要
设计了一种浮式基于CO2预冷—N2-CH4膨胀制冷液化天然气流程。对流程进行了模拟和比较，结果显示，该流程比功耗为0.54 kWh/m3，液化率为91.0%，综合性能优异。对流程进行了参数分析，分析结果对实际生产具有一定指导意义。
Abstract
A floating process to liquefy natural gas is designed based on CO2 pre-cooling and N2-CH4 expansion refrigeration.This process is then simulated and compared.The results show that the specific power consumption of this process is 0.54 kWh·m-3,and the liquefaction rate of natural gas is 91.0%,indicating an excellent comprehensive performance.The parameters analysis is carried out on this process,and the results have a certain guiding significance for the actual production.
