摘要
测定了大港油田羊三木油区减二线油和减四线油的蜡、沥青质、芳烃含量,结果表明两者蜡和沥青质含量均较少,可不经处理用于磺化,其芳烃含量分别为42.4%或38.2%。以氮气抽提发烟硫酸而得稀释SO3气体作为磺化剂,得出减二线油直接磺化粗产品率比减四线高出12.3%,因而选用了减二线油进行合成。但要提高磺化产率,需进行复配优化处理,筛选大港减二线油与重烷基苯以6∶4进行复配,粗产品的收率达到90.3%。并在此基础上,以中和值、活性物含量、不磺化物含量和无机盐部分作为评价指标,对磺化反应影响因素进行了优化:反应温度50～55℃,反应时间5h,SO3气体平均浓度4.5g/L,稀释混合气流速为140L/h。经中和后无需分离直接得到了性能稳定的石油磺酸盐表面活性剂。
The content of wax ,pitch and arene into vacuum cutⅡand that of vacuum cut Ⅳ from Da Gang′s Yang San Mu oil field are determined. The result shows the content of wax and pitch is comparatively low, and the content of arene is 42.4% and 38.2% respectively,so the kinds of oil could directly be sulphonated. Dilute SO3 as sulphanation dose is extracted from smoking sulphuric acid with nitrogen. Direct sulphonation rate of vacuum of it to heavy alkyl benzene is 6:4,the productivity of crude product reaches 90.3%.Influence factors of reaction are optimized with neutralization value, active thing content,un-sulphonation thing content and inorganic salt as evaluation standards.The result indicates that the optimal reaction conditions are as follows: reaction temperature 50～55℃.Reaction time 5h and SO3 average concentration of 4.5g/L,current of diluted gas 140L/h.After neutralized with alkali,the petroleum sulphonate with steady performance is obtained without separation from reaction fluid.
