南帕斯凝析油硫类型特征及其腐蚀性

摘要

The characteristics of South Pars condensate and the distribution of sulfur containing compounds in its light ends were investigated. Test results show that South Pars condensate belongs to sweet paraffinic base crude oil having low density and low impurity content,yet high in mercaptan content. The corrosion behavior of this condensate and its distillates was studied by copper strip test and high temperature autoclave strip test. Based on the test results,it can be seen that the corrosion of South Pars condensate at low temperature is not significant,but attention should be paid to the corrosion behavior of this condensate and its diesel distillate at high temperature (300 ℃).%考察了南帕斯凝析油的特性及轻端不同类型硫化物的分布情况.结果表明,南帕斯凝析油属于低硫石蜡基原油,密度较小,杂质含量较少,但硫醇硫含量很高.通过铜片腐蚀和高压釜挂片腐蚀模拟试验,研究了南帕斯凝析油及其馏分油的腐蚀情况,结果表明:低温时各馏分的腐蚀性不强,而在300℃高温下,凝析油及其柴油馏分的腐蚀性较强.
