The development of combined diesel oil and paraffin oil hydrodistillation technology at home and abroad is reviewed.The development status and trend of combined diesel oil and paraffin oil hydrodistillation technology in China are analyzed by taking a hydrogenation fractionation unit in north China,an integrated unit in south china and an enterprise in Luoyang as examples.It pointed out that in the face of the substantial growth of china's hydrogenation capacity since the 1990s,the process level has been significantly improved,but in the face of the increase in the processing volume of imported sour crude oil faced by China's refining industry,environmental protection requirements are increasingly strict,clean fuel is imminent,and international oil prices are rising for a long time,requiring the production of high-grade lubricating oil base oil and other new situations still cannot meet the needs.In the future,it is necessary to accelerate the development of diesel hydrogenation-rectification combined process,maximize the conversion of oil into clean energy,and constantly improve the level of hydrogenation technology in our country.
