| 摘 要： | 介绍了一种通过比较预加氢反应器进料与生成油换热器、汽提塔进料与塔底油换热器、汽提塔进料与分馏塔塔底油换热器以及预加氢进料与分馏塔顶油换热器油样中总硫含量的变化来分析与判断预加氢进料换热器内漏的方法.正常生产情况下,预加氢精制油中总硫的含量应该是比较低的.如果精制油中总硫质量分数超过0.5%,则或是催化剂活性下降,或是相...

| Abstract: | A method is presented for the analysis and diagnosis of the pre-hydrotreating feed/product heat exchanger leak through the analysis of the changes of sulfur content in pre-hydrotreating feed/product heat exchanger,stripping tower feed/bottom oil heat exchanger,stripping tower feed/ bottom oil of fractionating tower heat exchanger,pre-hydrotreating feed/overhead oil of fractionating tower heat exchanger.In normal operating conditions,the total sulfur in pre-hydrotreated oil is lower.If sulfur in pre-hydrotre... |
