巯基三氮唑在天然气输送管道减阻性能的研究

摘要

合成了一种新型天然气减阻剂3-烷基-4-胺基-5-巯基-1,2,4-三氮唑(AAMT),在天然气减阻剂室内评价系统上进行了减阻率测试,通过电化学分析及扫描电子显微镜对其在钢铁表面的成膜性能进行研究.结果表明:AAMT能够牢固吸附在输气管道内表面上形成一层光滑的弹性分子膜,显著改善了输气管道内表面的粗糙度.在AAMT浓度为4g/L、成膜时间为1.5h时,测得最大减阻率为10.03％.%A new natural gas drag reduction agent 3-alkyl-4-amino-5-mercapto-triazole (AAMT) was synthesized.The drag reduction efficiency of AAMT was tested on the drag reduction test loop,The film-forming property of AAMT was studied by electrochemical characterization and SEM.The results show that AAMT adsorbs on the iron surface and smooth membrane is formed,The roughness of the gas pipeline is significantly improved.Under the condition of 4g/L AAMT and 1.5h,the maximum drag reduction efficiency is 10.03 ％.
