| 摘 要： | 国内油气资源分散、单井产量小,边远地区的油气资源较丰富,可以利用小型液化天然气装置制成LNG后外输,同时小型天然气膨胀液化工艺又是我国LNG研究工作的重点。利用Aspen Hysys软件对N2-CH4膨胀制冷液化流程进行模拟、研究和分析,得出影响该流程的主要参数:制冷剂高压压力、主换热器出口温度、制冷剂氮气含量、天然气进料压力和LNG储存压力对液化率和比功耗的影响。

| Abstract: | Oil and gas resources in China scatter, single well yield is small, oil and gas resources in rural areas are rich. Small-scale gas liquefaction device can be used to prepare LNG for transportation; at the same time, small-scale natural gas liquefaction process has been the focus of LNG research in our country. In this paper, N2-CH4 expansion refrigeration liquefaction process was simulated, researched and analyzed with the software of Aspen Hysys. Main parameters affecting the process were determined as follows：refrigerant higher pressure, the outlet temperature of the main heat exchanger, nitrogen content, feed gas pressure and LNG storage pressure. |
