摘要
介绍了加氢装置减压塔改造的工艺流程及工艺参数的调整,并将改造前后的操作状况进行了对比。解决了常压柴油收率低、减压柴油质量不稳定、操作难度大、减压柴油与重柴重叠严重、重柴拔出率低等问题,重柴油产量由2.5 t/h提高到4.0t/h,柴油总体收率也得到了提高。
The transformation process of hydrogenation unit vacuum tower and the adjustment of the process parameters are performed. The operating conditions before and after technical innovation are compared. The problems such as low yield of atmospheric diesel, unstable quality of vacuum gas oil, difficult to operate, seriously overlapping of vacuum gas oil and heavy diesel, low extraction rate of heavy diesel, and so on, are solved after technical innovation in this study. The yield of heavy oil has been improved from 2. 5 t/h to 4. 0 t/h and the overall yield of diesel has also been improved.
