在天然气管线中 ,水合物会堵塞管道 ,损坏设备。分析了天然气管道内水合物形成过程和预测方法 ,编制了天然气管道水合物预测软件。介绍了天然气管道全线运行参数的确定 (包含稳态和动态 ) ,天然气管道全线所允许的最大含水量的确定和天然气管道全线实际含水量的计算方法。通过比较天然气管道全线所允许的最大含水量和实际含水量 ,来判断全线是否有水合物生成
In natural gas lines, hydrates can clog pipes and damage equipment. The formation process and prediction method of hydrate in natural gas pipeline are analyzed, and the prediction software of hydrate in natural gas pipeline is compiled. This paper introduces the determination of the full range of natural gas pipeline operation parameters (including steady state and dynamic), the determination of the maximum allowable water content of natural gas pipelines and the calculation of the actual water content of natural gas pipelines. By comparing the maximum allowable water content and the actual water content of the natural gas pipeline to determine whether there are hydrate formation across the board
