| 摘 要： | 介绍了济钢焦化厂焦油常、减压蒸馏的工艺流程、生产实践。在生产过程中通过增加沥青换热器,解决了焦油主塔抽出泵效率低的问题,并通过控制焦油水分、主塔顶温度、蒽油采出量等,解决了管道堵塞问题,保证了生产稳定。同时,为更好地控制沥青软化点,建议在主塔之前增加1个闪蒸器。

| Abstract: | The process flow and production practice of air-distillation and reduced-pressure distillation for tar in Jigang coking plant are introduced. In the productive process, the inefficient problem of withdrawing pump of the main tower is settled by adding asphalt exchanger and through controlling the moisture of tar, the temperature of the main tower top, the capacity of the picking out anthracene oil, the problem of the pipe clogging is solved and stable production is pledged. At the same time, in order to control the softening point of the asphalt well, a suggestion of adding one flash type evaporator before the main tower is put forward. |
