Oil refining auxiliaries and oil refining catalysts, petroleum product additives are known as the "three agents" in the oil refining industry. Although the amount and importance of oil refining auxiliaries are not as high as the latter two, they are also an essential part of the oil refining industry. Today this article xiaobian details to talk about the main role of oil refining additives.

The main functions of oil refining additives can be divided into the following eight parts:

①The activity and selectivity of protection cracking catalytic liu (passivating agent, vanadium fixing agent, fluidization aid);

②Inhibit the corrosion of equipment, prevent the blockage of equipment, prolong the operation cycle (corrosion inhibitor, scale inhibitor, defoamer);

③Improve processing capacity (filter aid for run-lubricating oil dewaxing device);

④Ensure stable operation (demulsifier, calcium remover);

⑤Increase the yield of light oil and increase the ratio of diesel to gasoline (oil cracking at the bottom of the tower helps);

⑥Improve product distribution and product quality (octane number additives, isomerized olefin additives);

⑦Energy saving and consumption reduction (CO combustion agent, also has the effect of reducing exhaust pollution);

⑧Reducing environmental pollution (sulphur transfer AIDS);

In fact, people in the industry know that compared with the catalyst, the price of oil refining additives is much more expensive, but because of the small amount, the effect is large, there is still a great profit. The correct choice and rational use of oil refining auxiliaries can get twice the result with half the effort.

In recent years, domestic and foreign oil refining auxiliaries have attached great importance to the research and development of auxiliaries. It is expected that oil refining additives will have great development potential. In addition, with the increase of crude oil's heavy and inferior quality, as well as the demand for light oil in high quality, the improvement of oil quality requirements and the implementation of environmental laws and regulations, the diversification of oil refining additives is also a topic that many people in the industry have been exploring.
