摘要: 对国内某炼油厂的常减压蒸馏、加氢裂化、连续重整、柴油加氢、渣油加氢、酮苯脱蜡、糠醛精制、重油催化裂化等21套装置进行全面采样和分析,考察了含氮原油在炼油厂各工艺流程中的分布及传递情况,确定了各装置的氮元素平衡及分布规律,绘制了全厂氮元素传递图,以期为炼油厂深度脱氮、重点装置防腐以及工艺升级等提供技术支撑。

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.

Key words: crude oil processing, nitrogen balance, nitrogen distribution, nitrogen transmission, nitrogen characterization, corrosion
