At present, in order to solve the problem of easy scaling of key equipment in the process of oil processing, domestic researchers have conducted a lot of research on scale inhibitors and developed scale inhibitors with strong target and obvious scale inhibition effect; according to their use, they can be classified into FCC slurry scale inhibitor and hydrocracking scale inhibitor.

In response to some problems in the refining process and the addition of one or more fine chemical products as supplementary additives, this type of refining additives have the characteristics of targeted, convenient and flexible, can play a role in improving the catalyst as well as the refining process and equipment.

Zinc oxide desulfurizer is widely used in the fine desulfurization of various petrochemical raw materials gas and industrial gas, with the advantages of high desulfurization precision and large sulfur capacity. Zinc oxide desulfurization agent is divided into normal temperature zinc oxide desulfurization agent and medium temperature (high temperature) zinc oxide desulfurization agent, the former's use temperature 10 ~ 120 ℃, the latter is 220 ~ 450 ℃, clover appearance, 30% increase in external surface area.

Desulfurization agent, generally refers to the agent that removes free sulfur or sulfur compounds from fuels, raw materials or other materials; in the control and treatment of pollutants, it mainly refers to the agent that can remove sulfur oxides (including SO2 and SO3) used in exhaust gases.

The oxidizing agent improves the reaction efficiency of SO2 to SO3 conversion and sulfite to more stable sulfate conversion, and the polymer activator can reduce the reaction temperature of these two processes, while some groups of the polymer can directly capture SO2 to generate organic sulfate.

Desulfurizing agent is not a dangerous product. The common desulfurizing agent is calcium hydroxide, which is a strong alkali and has certain corrosive effect on the skin.
