针对原油变重的问题 ,胜利炼油厂在常减压蒸馏装置上采用强化蒸馏添加剂 ,只需增加添加剂的加入和混合设施 ,在不改动原有工艺流程和操作条件的情况下进行了工业应用试验。结果表明 ,加入 5 0 μg/g的添加剂T118和T2 18 A可分别使减压蜡油的平均收率 (对原油 )提高 1.0 4个百分点和 1.41个百分点 ,并且可改善减压蜡油的质量 ,是一项适合国情的重油加工技术。 In view of the problem of heavier crude oil, Shengli Refinery adopts the enhanced distillation additive in the atmospheric and vacuum distillation unit, only needs to add the additive adding and mixing facilities, and carries out the industrial application test without changing the original technological process and operating conditions . The results showed that the addition of 50 μg / g of T118 and T2 18 A respectively increased the average yield of vacuum gas oil (for crude oil) by 1.0 4 and 1.41 percentage points, and improved the quality of vacuum oil , Is a suitable heavy oil processing technology.
