| Abstract: | 21 units including atmospheric and vacuum distillation, hydrocracking, continuous reforming, diesel hydrogenation, residue hydrogenation, ketone-benzol dewaxing, furfural refining, and heavy oil catalysis etc. in a domestic refinery were comprehensively sampled and analyzed. The distribution and transmission of nitrogen-containing crude oil in various processes of refinery were investigated, the balance and distribution of nitrogen elements in each unit were determined, and the nitrogen diagram of the whole plant was drawn, in order to provide technical support for deep denitrification in refinery, anticorrosion protection in key units and process upgrading. |

| Keywords: | crude oil processing nitrogen balance nitrogen distribution nitrogen transmission nitrogen characterization corrosion |
