我国第一套40万t／a润滑油高压加氢装置现已在兰州炼油化工总厂基本建成，预计1996年6月投料开工。这套40万t人润滑油高压加氢装置主要加工中间基原油，原油经过加氢处理后与原老装置相结合，所生产的基础油粘度指数高（最低为95，最高达125），紫外安定性好，性质优良，可以调 China’s first set of 40 million t / a high-pressure hydrogenation unit of lubricating oil is now basically completed in Lanzhou Refining & Chemical Plant, expected in June 1996 to start the project. The 400,000-ton high-pressure hydrogenation unit of lubricating oil mainly processes intermediate crude oil. After crude oil is hydrotreated and combined with the old unit, the produced base oil has high viscosity index (minimum 95 and maximum 125), ultraviolet Good stability, good quality, can be adjusted
