| 摘 要： | 带丙烷预冷的混合制冷剂循环（MRC）液化天然气流程具有高效及流程相对简单的优点，丙烷预冷循环首先预冷天然气和混合制冷剂，然后由混合制冷剂循环进一步冷却天然气使其液化。本文对这种带丙烷预冷的混合制冷剂循环液化天然气流程分别以丙烷预冷循环中压缩机耗功最小，总耗功最小为目标函数进行优化，得到了最优流程参数及相应的流程性能参数。

| Abstract: | The procedure of liquefying natural gas by propane precooled mixed refrigerant cycle(MRC) is of the advantages as high effectiveness and relative simplification. Propane precool cycle is to precool natural gas and mixed refrigerants first, then the natural gas is further cooled and then liquefied by mixed refrigerant cycle. In the paper, through optimizing by taking the minimum power consumption of the compressor in propane precool cycle and its minimum total power consumption as the aim functions, the optimal process parameters and corresponding process performance parameters are obtained for the procedure of liquefying natural gas by propane precooled mixed refrigerant cycle. |
