摘要
应用统计热力学方法,研究了不同含量H2S对湿气输送管道形成天然气水合物压力和温度条件的影响,并使用HYSYS软件对高含硫湿气输送管道压力和温度的变化规律进行过程模拟。结果表明H2S含量越高,越容易形成水合物;高含硫湿气输送管道的压力变化和温度变化趋势相似,水相的存在加剧了管道压力和温度的变化,上坡处管道更易形成水合物;在高压条件下,低水相含量即可形成饱和自由水环境,且水相含量相对较高的气流更易形成水合物。
Influence of different H2S contents on pressure and temperature of natural gas hydrate formed in wet gas pipeline is researched with statistic thermodynamics method,and process simulation on variation law of pressure and temperature of high-sulphur wet gas pipeline is carried out by means of HYSYS software.Results show that the more H2S content is,the easier hydrate forms; variation tendency between pressure and temperature in high-sulphur wet gas pipeline is similar,the existence of water phase intensifies the variation of pressure and temperature of pipeline,and hydrate is easier to form at uphill pipeline; under the condition of high pressure,low water phase content would form saturated free water environment and even gas stream with relatively high water phase content is easier to form hydrate.
