Butter inhibitors

Features and Applications

Inhibit condensed or soluble unsaturated hydrocarbon fouling during cracked gas amine washing and caustic washing 

It has antioxidant, inhibitor, clean dispersion and metal ions Passivation

Without Halogen and heavy metals, soluble with water,amine and lye no harmful to enviroment.

No adverse effects on downstream operations and product.

Mainly used for ethylene plant cracking gas amine washing systems and caustic washing systems.


Butter inhibitors before alkali injection pump, it can also inject in a weak base and a strong base at the same time with the dosing point corresponding pump.

Dosage is 30 ~ 150ppm, can be added at the beginning of the use of 100 ~ 150ppm run for several days, then reduced to 30 ~ 50ppm, to observe the effect and decide to increase or decrease and to determine the optimum injection amount

Continuously add into amine caustic washing systems with plunger metering pump  or to be diluted to a certain concentration solution  as needed.

Packaging and Storage

Plastic barrel, 25kg per barrel or customization. Store in a cool ventilated place, avoid direct exposure to sunlight。

Security and Protection

Butter inhibitor is strongly acidic, labor protection during laber, should avoid contact with eye and skin, once contacted, flush with plenty of water. In severe cases, immediate medical attention.
