摘要/Abstract

摘要：

中国非常规天然气资源极其丰富,小型天然气液化装置能有效地改善这些非常规天然气的开采现状,具有非常广阔的前景。采用HYSYS^®软件对精馏型自复叠小型液化天然气系统进行了流程模拟计算,分析了系统中混合制冷剂组分对系统单位液化功、排气温度等性能的影响规律,并对混合制冷剂的配比进行了优化,得到了最佳配比。并分析了在该配比下系统3个回热器内3股流体的温度分布,说明了该配比下系统各方面性能均较佳的原因。

Abstract:

The unconventional natural gas is very abundant in China. Small scale natural gas liquefiers can be effectively used for the extraction of the unconventional natural gas with a very promising future. In this study, a small scale auto-cascade natural gas liquefier using a rectifying column was simulated by HYSYS^®. The influence of compositions of refrigerant mixtures on the energy consumption for the liquefaction of per unit LNG and the discharge temperature of the liquefier, was analyzed. Concentrations of the refrigerant mixtures were optimized and the optimum concentrations for the specified operating condition were obtained. The temperature profiles of three recuperators in the system with the optimum concentrations were also investigated to analyze the efficiency elevation of the system.

Key words: mixed refrigerant, auto-cascade, LNG, optimization
