新型咪唑啉缓蚀剂对20钢的缓蚀效果OA
New Imidazoline Corrosion Inhibitors on Steel 20
以油酸、二乙烯三胺为原料,合成了油酸咪唑啉缓蚀剂HS11.采用失重法研究了缓蚀剂HS11及其与油田常用的缓蚀剂JCCR1138、高温缓蚀剂复配后对20钢的缓蚀效果,并结合现场腐蚀产物进行了XRD衍射图谱分析,研究了稠油减粘裂化装置冷却器的腐蚀原因.结果表明:冷却器内同时存在氧化腐蚀和低温HCl- H2S-H2O腐蚀,在HC1- H2S- H2O腐蚀中硫是腐蚀的主要原因；缓蚀剂HS11的最佳质量分数为200 μg/g,此时缓蚀率可达74.31％；…查看全部>>
Oleic acid imidazoline HSU is synthesized from oleic acid and dielhylene iriamine. Inhibitor's performance is evaluated by weight — loss method and the effect after matching with commonly used inhibitors JCCR1138 and Gaowen is also researched. The corrosion mechanism of the water cooler system in viscosity breaking unit is analyzed by means of X-ray diffraction. The results indicate that main corrosion form is not only the oxidation corrosion, but also HC1 —…查看全部>>
