金属轧制油所需基础油的来源与生产
|
摘要
金属轧制油所需的基础油黏度较低,主要来源于石油中的常压馏分和部分减压馏分,还可从加氢油或合成油中分馏提取,但对馏程范围有严格的要求,需要经过精密分馏制取。而石油加工企业普遍缺少精密分馏装置,轻质馏分多被用来制备溶剂油、煤油和柴油,因此金属轧制油基础油的制备受到一定限制。在目前产能过剩、燃料油市场饱和的形势下,石油加工企业可通过对石油、加氢油与合成油的轻组分进行精密分馏,制备不同黏度的轻质基础油来满足金属轧制油的生产需求,并以此提高石油产品附加值。此外冶金行业也十分重视金属材料的深加工,对轧制油的需求潜力十分巨大。
Base stocks for metal rolling oils are mainly from atmospheric distillates and some vacuum distillates,or are extracted by fractionation from hydrocracked oil or synthetic oil,with lower viscosity. But they must be manufactured by super fractionation because of the strict requirement for the range of distillation. However,petroleum processing enterprises generally lack super fractionation equipments,light fractions are often used to prepare solvent oil,kerosene and diesel oil,so the preparation of base oils for metal rolling oils are restricted. In the current situation of overcapacity and the saturation of the fuel oil market,petroleum processing enterprise can produce light base oils with different viscosity to meet the production of metal rolling oils by super fractionation of light components of crude oil,hydrocracked oil or synthetic oil,so as to increase the added value of petroleum product. In addition,the metal working industry also attaches great importance to the deep processing of metal materials,and the demand of rolling oils will have great potential.
