[Abstract]:With the increasing demand for high-specification lubricating oil, full-hydrogen process is more and more widely used to produce high-specification lubricating oil. In order to meet the demand of domestic market for high specification lube base oil, refineries are popularizing the production of high specification lube base oil. In this paper, 300000 t / a "total hydrogen process" lubricating oil hydrogenation process was designed, and the whole process was simulated and optimized by HYSYS process simulation software. The energy of the process is optimized by comparing the simulation data with the field data, including a reaction feed / product heat exchanger, a stripping tank top gas / hydrogen mixing heat exchanger, and a stripping tank top gas / circulating hydrogen exchanger. The heat transfer temperature difference is increased, and the energy consumption, electricity consumption and gas consumption of the unit are reduced. The recirculating hydrogen desulfurization tower is simulated and optimized, including the absorbent temperature, the amount of absorbent, the number of trays, etc. The optimum operating condition of circulating hydrogen desulfurization tower was determined. The simulation study of atmospheric pressure column process was carried out, and the relationship between steam consumption and 5% distillation temperature of constant bottom oil and heat load on top of tower was established. Finally, an economical steam stripping amount of .4 was established, the heat transfer process of the third line (base oil 3) was optimized, and the heat exchanger of the low amine liquid was added, which satisfied the requirement of preheating of the low amine liquid and reduced the heat load of the base oil 3 air cooler. At the same time, the energy consumption of the unit is reduced, and the thermal stability of the amine-poor solution is solved at the same time. This technology can be used to produce qualified oil of 4# transformer oil 15# refrigerated oil 12# and 16# rubber filling oil, which can meet the requirement of sulfur content of API-1509 class 鈪，
