炼厂天然气调压系统长周期运行分析

Analysis of Long Cycle Operation of Natural Gas Pressure Regulating System in Refinery

随着国家管网天然气输送的发展,高压压缩天然气已逐步进入炼厂,成为炼厂燃料气供应、天然气制氢的重要原料。使用过程中,设备选型、减压撬装压力设定、操作测试、维护保养等都将直接影响天然气调压系统的平稳运行,探索一种从设计、维护保养、操作平稳的固化管理经验,有助于保障调压系统稳定、长周期运行。

With the development of national pipeline network natural gas transmission,high-pressure compressed natural gas has gradually entered the refinery,becoming an important raw material for refinery fuel gas supply and hydrogen production from natural gas.During the use pro-cess,equipment selection,pressure setting for pressure reducing prying,operation testing,and maintenance will directly affect the smooth operation of the natural gas pressure regulating system.Exploring a solidification management experience from design,maintenance,and smooth operation can help ensure the stable and long-term operation of the pressure regulating system.
