In recent years, due to the rapid development of oil refining auxiliaries, many research institutions at home and abroad have been devoted to the development of this field. In order to meet the needs of the continuous development of oil refining industry, in addition to the existing oil refining auxiliaries have been gradually improved, a number of new varieties have been published every year in response to the new problems in the process of oil refining.

Refining auxiliaries are a kind of fine chemical products with strong pertinence and flexibility. It is an indispensable complement and improvement to oil refining catalyst and oil refining equipment.

Oil refining auxiliaries are composed of organic compounds, such as oil soluble metal compounds, catalysts, strong solvents, dispersants, ash improvers and flow agents. Used in metallurgy, electric power, oil refining and industrial combustion of diesel, heavy oil (residue), furnace and boiler as a strong energy saving agent.

There are many kinds of oil refining auxiliaries. From the use function can be divided into five categories: (1) to improve the product quality of the class of additives: such as reduce the catalytic cracking gasoline olefin additives, reduce the catalytic cracking gasoline sulfur content additives, increase the octane number of gasoline additives; (2) environmental additives: such as reducing SOx and NOx emissions in catalytic cracking recycled flue gas; (3) to extend the start-up period of the device and reduce energy consumption of auxiliary agents: such as a variety of scale inhibitors and coke inhibitors, corrosion inhibitors; (4) to improve the properties of raw materials and catalyst activities of auxiliary agents: such as crude oil demulsifier, calcium, catalytic cracking metal passivation agent; (5) improve the distribution of product additives: such as tower bottom oil cracking additives, increase the yield of light oil additives.

At present, the application of oil refining auxiliaries has been quite common, and almost every refinery unit USES oil refining auxiliaries in different degrees. Oil refining additives have great development potential and market prospects.
