青岛市北冠县路街道经销壳牌液压油-导轨油矿物油 通常是指经过开采和初加工的原油(或石油)，mineral oil，石油是埋藏于地下的天然矿产物，经过勘探、开采出的未经炼制的石油也叫做原油。在常温下，原油经过炼制后的成品叫做石油产品。依据习惯，把通过物理蒸馏方法从石油中提炼出的基础油称为矿物油基础油。提炼加工过程主要是将原油分成不同的部分以得到所需产品。主要的分离过程包括将原油分离成粗汽油、粗煤油、粗柴油、重柴油、各种润滑油馏分、裂化原料油及渣油(又称残油)的蒸馏分离和将各种润滑油提纯所使用的溶剂分离。生产过程基本以物理过程为主，不改变烃类结构，生产的基础油取决于原料中理想组分的含量与性质;矿物油在提炼过程中因无法将所含的杂质清除干净，因此得到的基础油流动点较高，不适合寒带作业使用;因此，矿物油类基础油在性质上受到一定限制。Mineral oil usually refers to crude oil (or oil) that has been exploited and initially processed. Mineral oil is a natural mineral that is buried in the ground. At room temperature, crude oil is refined into a finished product called a petroleum product. According to the custom, the physical distillation method from the oil of the base oil known as mineral oil base oil. The refining process consists mainly of dividing the crude oil into different parts to produce the desired product. The main separation process includes the separation of crude oil into crude gasoline, crude kerosene, crude diesel oil, heavy diesel oil, all kinds of Lube oil fractions, cracking oil and residue (also called residual oil) distillation separation and purification of all kinds of Lube oil used in solvent separation. The basic oil produced depends on the content and properties of the ideal components in the feedstock, and the impurities in the mineral oil can not be removed completely in the refining process, therefore, the obtained base oil has a high flow point and is not suitable for cold zone operation.
