Several MRC cycles for Liquefied Natural Gas (LNG) production were analyzed in this paper,--Based on the thermodynamic properties of natural gas and mixed-refrigerant, the Peng-Robinson (PR) equation was selected to calculate the phase equilibrium. The cold box in the liquefaction cycle was simulated by used HYSYS software, the model was established and the components of the mixed refrigerant influence on liquefaction process were studied.Key words: MRC; simulation; HYSYS; cold boxII下载后可任意编辑目 录第 1 章 前 言......................................11.1 工业背景和讨论意义.........................11.1.1 世界液化天然气工业的进展..............21.1.2 中国液化天然气工业的进展..............21.2 国内外讨论现状.............................41.3 讨论内容...................................5第 2 章 混合制冷液化流程...........................62.1 混合制冷液化流程...........................62.2 混合制冷剂液化流程的分类...................62.2.1 闭式混合制冷剂液化流程................62.2.2 开式混合制冷剂液化流程................82.2.3 丙烷预冷混合制冷剂液化流程............92.2.4 CII 液化流程..........................122.2.5 新型两级混合制冷剂液化流程...........14第 3 章 冷箱................................
