摘　　要：针对青岛LNG接收站BOG处理过程中LNG提供冷量不足引起管道振动、阀门异常现象进行优化模拟研究。基于青岛LNG接收站BOG处理单元实际运行工艺,以Aspen HYSYS流程模拟软件为研究手段对各问题现象点进行分析研究,建立符合实际流程的LNG接收站稳态模型,寻找关键工艺节点,以各设备安全运行的同时降低能耗为目标,对卸船与非卸船两种工况下的各节点进行可操作参数优化研究,得出不同BOG产生量下各节点对应的最小LNG冷凝需求量。同时对不同设备所需的LNG冷凝量变化进行对比分析,得出相应的敏感性大小。所得结果可为现场实际生产运行提供理论参考。An optimization simulation was carried out to solve the pipeline vibration and valve anomalies caused by insufficient LNG supply during the BOG treatment in Qingdao LNG terminal.Based on the actual operation process of the BOG handling unit of Qingdao LNG terminal,Aspen HYSYS was used to analyze the problem points of each problem,establish a steady-state model of LNG terminal that conforms to the actual process and search for key process nodes.Aiming at the safe operation of each equipment and the reduction of energy consumption,the operational parameters of each node under the conditions of unloading and nonunloading were optimized,and the minimum LNG condensation demand corresponding to each node under different BOG production was obtained.The changes of LNG condensation required by different equipment were also compared and analyzed,and the corresponding sensitivity was obtained.The results obtained can provide theoretical reference for actual production and operation on site.
