The distribution status of the synthesis reactor distributor in a 160000 t/a coal-to-oil (CTL) project in Yitai company directly affects the stable operation of device. Through continuous structure reconstruction, the reactor distributor has uniform gas distribution and good bubbling effect, which eliminates the security risk and solves the problems of device operation. ©, 2014, China National Chemical Information Center.

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. ©, 2015, Xiandai Huagong/Modern Chemical Industry. All right reserved.

The problems about the operation of the water treatment unit in a 160000 t/a coal-to-liquefaction demonstration project in Yitai company are introduced. Based on the actual operation, the influencing factors of the scaling of the water system are analyzed. The corresponding optimizing operations are proposed, including strengthening ash water quality management, strengthening flocculent and dispersant, monitoring the analysis of coal, and so on. ©, 2014, China National Chemical Information Center.
