Abstract:

The technology of novel and high efficient hydrogenation reactor was introduced in this paper, with the related industrial application on the heavy oil hydrogenation units, which were developed by Research Institute of Petroleum Processing. Compared with existing technology, the overall logistics mixing and distribution performance are excellent with the new type hydrogenation reactor internals. The liquid phase distribution of the uneven factor is only 0.08 and the overall utilization rate of the catalyst was 95%. The flat structure can make the larger space for the 300mm ~ 500mm height of the bed catalyst. The Industrial application results showed that, the difficulty problems about the poor distribution effect of logistics and hot point in reaction bed, existed in the use of the deterioration of the heavy oil hydrogenation units. These could be solved through the new type of high efficient hydrogenation reactor internals. Also the average radial temperature difference of the catalyst bed is only 5.3 ℃, and it allows greater axial temperature rise. This could provide a reliable technical support the long period and high efficient operation for the units.
