中文摘要	从热力学的角度出发,详细分析了撬装型混合制冷剂液化流程SP-MRC的关键参数对流程性能(包括比功耗、液化率、比制冷剂流量和比冷却水负荷)的影响。这些关键参数包括:分离器S1和S2的温度;高压制冷剂和低压制冷剂的压力;天然气的入口压力和LNG的储存压力;天然气的组分;混合制冷剂的组分。; In this paper,how the key parameters of mixed refrigerant cycle of small scale natural gas liquefaction process in skid-mounted package affect the process performance(including specific power consumption,liquefaction rate,specific refrigerant flowrate and specific cooling water charge)is labored from thermodynamic point of view.These key parameters include temperature of separator S1 and S2, pressure of mixed refrigerant,inlet pressure of natural gas and storage pressure of LNG,components of natural gas and mixed refrigerant.The optimizer of original mode in Aspen HYSYS is used to optimize SPMRC (mixed refrigerant cycle in skid-mounted package)and find the operating conditions which minimize LNG specific power consumption(objective function).The research reveals that the change of temperature, pressure and component fraction at the same time will influence the process performance remarkably.The new SP-MRC adopts the technology of integral incorporated cascade which combines heavy and light hydrocarbon.It can reduce the quantity and volume of compressors and heat exchangers in the guarantee of higher liquefaction rate and lower specific power consumption.; 【作者单位】集美大学机械工程学院；上海交通大学制冷与低温工程研究所；【作者英文名】CAO Wensheng~1 WU Jiying~1 LU Xuesheng~2 LIN Wensheng~2 GU Anzhong~2 (1 College ofMechanical Engineering,Jimei University,Xiamen 361021,Fujian,China; 2 Institute of Refrigeration and Cryogenics,Shanghai Jiao Tong University,Shanghai 200240,China)
