摘　　要：天脊集团苯胺生产工艺采用硝基苯液相加氢技术,为了节约生产成本,降低苯胺生产过程中氢气的消耗,在现有的苯胺生产装置上提出了一些优化操作,实现了氢气单耗的降低。2021年,吨苯胺耗氢为774.6 m^(3),相比较2020年786.39 m^(3),氢气单耗下降了11.8 m^(3)/t。按财务数据1.5元/m^(3)氢气计算,2021年实际完成苯胺产量26.1万t,节约成本461.9万元,对提升苯胺制备的经济性具有十分重要的意义。The aniline production process of Tianji Group adopts nitrobenzene liquid-phase hydrogenation technology.In order to save production costs and reduce the consumption of hydrogen in the production process of aniline,some optimized operations have been put forward on the existing aniline production unit to achieve the reduction of hydrogen unit consumption.In 2021,the hydrogen consumption per ton of aniline was 774.6 m^(3),compared with 786.39 m^(3) in 2020,and the unit hydrogen consumption decreased by 11.8 m^(3)/t.According to the financial data of 1.5 yuan/m^(3) hydrogen,the actual output of aniline will be 261000 tons in 2021,saving 4619000 yuan in cost,which is of great significance to improve the economy of aniline preparation.
