| 摘 要： | 截止2013年底,我国天然气主干管道总里程超过了6万km,未来我国天然气管道的管径、压力、钢级将进一步提升。高压天然气需经过调压才能进入中压管道,但传统调压方式仅仅是进行节流,造成了压力能的浪费。探讨利用高压管网与中压管网之间的压差进行液化调峰,这里应用ASPEN HYSYS软件对流程进行了模拟,分析了分流器分流比、中压管网压力变化、气源压力变化、气源温度变化和气源流量变化对流程液化率的影响,并得出相应的结论。

| Abstract: | By the end of 2013, China＇s natural gas main pipelines total mileage was over 60,000 km. In the future, diameter, pressure, steel grade of natural gas pipelines in our country will further improve. High pressure natural gas’s pressure need be adjusted before entering medium pressure pipeline. But the traditional way of regulating the pressure is just throttling, which can cause pressure energy waste. In this article, using pressure difference between high-pressure and medium pressure pipelines to liquefy natural gas was discussed. Here ASPEN HYSYS software was used to simulate the process. Effects of the split ratio, pressure change of medium and high pressure pipelines, inlet temperature change of high pressure gas flow, and flow rate change of high pressure pipeline on the liquefaction rate were analyzed, and the conclusion was drawn. |
