通过比选各种液化流程的能耗及适应性优选出适合页岩气试采期单井液化流程;利用HYSYS模拟分析了单循环混合制冷液化工艺,比较了不同压力工况下液化流程的适应性及能耗变化。模拟计算可对国内试采期天然气回收利用提供参考。 By comparing the energy consumption and adaptability of various liquefaction processes, a single-well liquefaction process suitable for the shale gas test-production period was optimized. The single-cycle mixed liquefaction process was simulated by HYSYS, and the liquefaction process adaptability under different pressure conditions was compared Sexual and energy consumption changes. The simulation calculation can provide a reference for the recovery and utilization of natural gas during the trial run in China.
