离线气相色谱仪在中亚管输天然气中的应用

Application Offline GC Gas Pipeline in Central Asia

离线气相色谱仪在天然气领域中应用越来越广泛,本文通过使用离线气相色谱仪对中亚管输天然气中的硫化物和组分的检测,测定其硫化氢、羰基硫、甲硫醇、乙硫醇等硫化物的质量含量,以及二氧化碳、氮气和甲烷、乙烷、丙烷、丁烷等烷烃的体积含量,并对中亚管输天然气2014年全年气质进行分析以评定中亚管输天然气的品质优劣,确定其满足国家标准中所规定的一类气标准。

Off-line gas chromatograph in the gas sector is more and more widely used. By using the off- line gas chromatograph detection of Central Asia Gas Pipeline Sulfides and Components,hydrogen sulfide,carbonyl sulfide,methyl mercaptan,ethyl quality,content of mercaptan sulfur compounds,the volume fraction carbon dioxide,nitrogen and methane,ethane,propane,butane and other alkanes were measured. The annual temperament of Central Asia Gas Pipeline in 2014 were analyzed to assess the pros and cons of natural gas quality of the Central Asian Pipeline,it was determined that it met the gas national standards.
