Neutralizing corrosion inhibitor for Crude Units is mainly used to prevent the corrosion caused by hydrogen sulfide (H2S) ,and hydrogen chloride ,etc. at the distillation overhead of atmospheric and vacuum unit in the oil refinery. 


1.Water-solubility is good.

2.This product is compounded by many kinds of component.

  (1)When some kinds of gases dissolved into water ,such as H2S, CO2, SO2 ,etc. they will form the acid, this product can neutralize these kinds of acid and prevent acid corrosion after being injected.

  (2) This product includes film passivation technical recipes, and the passive film will form on the surface of the carbon steel pipe and equipment to prevent the corrosion.


The injecting amount should be 10~30ppm (Relative to the raw material)and should be doubled at the first month.


1.This Neutralizing corrosion inhibitor should be stored in aeration-drying , shady and cool storeroom .

2. During the process of application, the customer should choose the best service conditions according to the actual case of the factory.
