By refining, blending, and adding different additives as needed, semi-finished oil products can be fully qualified and commercially viable.

The refining is the process of removing certain non-ideal components and impurities from semi-finished oil, so that the oil meets the requirements of product quality indicators. There are many refining methods for petroleum fuel products, with different purposes.Commonly used methods include refining to remove sulfides from gasoline and diesel, removing petroleum wax from diesel, and removing olefins from commercial gasoline.

Oil blending refers to the rational use of semi-finished oils of different qualities, mixing them together to maximize and comprehensively meet the requirements of product quality. While ensuring the stability of product quality, the proportion of high-quality products in the finished oil is maximized to improve economic benefits. Blending can be divided into two categories. first,blending various semi-finished products in a certain proportion into base oil and qualified finished oil; second, blending base oil with additives.

Oil additive is a substance that can effectively and significantly improve one or several properties of oil by adding trace amounts to the oil. The use of additives can significantly improve the quality of oil products, improve processing technology, reduce costs,reduce fuel consumption, and sometimes even improve certain performance that is difficult to achieve through improved processes.Therefore, it has become one of the main means to improve the quality of oil products.
