摘要
介绍国外近年来润滑油临氢生产技术，并同惯用的溶剂法进行比较。从比较结果看，临氢法的优势是：流程简单，操作费用低；对原料要求不严格，即使用比较差的中东原油也能生产出高质量的润滑油基础油；目的产品产率高，质量好，性能接近合成油；副产品价值高；污染少。缺点是还不能生产粘度较高的光亮油和精蜡。因此，现代化润滑油厂的装置结构是：临氢法和溶剂法结合。
he result by contrast to conventional solvent method indicated that lubricating oil hydroprocessing technologies have both advantages and limitation.The advantages follow:the process flow is simple and the operating cost is low;it's not strict with raw material,even using the Middle East crude oil,the premium lubricating base oil also can be produced;the property of end products approach PAO's with higher yield and quality;the value of byproduct is higher with less pollution.And the limitation is that it can't produce bright stock with high viscosity and paraffin wax.So,the processing scheme of modern refinery is arranged through hydroprocessing method combined with solvent method,mainly using the hydroprocessing technology.
