分子炼油技术在1.2Mt/a柴油加氢装置上的应用
|
摘要
为解决中国石油兰州石化公司1.2 Mt/a柴油加氢装置在全催化柴油生产工况存在的原料硫形态复杂,反应苛刻度增加,催化剂活性下降,反应器出口温度受限等问题,采用分子炼油技术对操作工艺进行了优化。结果表明:通过采用将催化柴油原料的95%馏出温度控制在不高于370℃,反应器6个床层温度依次控制在320,384,385,385,375,375℃的优化措施后,装置实现了100%催化柴油生产,精制柴油产品可满足含硫量不大于10μg/g的国Ⅴ柴油标准。
In order to solve the existed problems of complex raw sulfur morphology, increased reaction severity, decreased catalyst activity and limited reactor outlet temperature under the full catalytic diesel production condition in a 1.2 Mt/a diesel hydrogenation unit of Lanzhou Petrochemical Company, PetroChina, the molecular refining technology was adopted to optimize the operation process. The results showed that 100% catalytic diesel oil production was achieved and the refined diesel product could meet the national standard V after the several measures were taken, such as controlling 95% distillate temperature of catalytic diesel raw material not higher than 370 ℃ and controlling the six reactor bed temperature at 320,384,385,385,375,375 ℃ in turn.
