KEM PR-4220

General Information

KEM PR-4220 is a hydrocarbon soluble, neutralising corrosion inhibitor. It condenses in the same temperature/pressure range as water and effec tively controls pH throughout the overhead system.

KEM PR-4220 will not form corrosive fouling salt deposits with chlorides present in the overhead condensate. The neutralisation molecule is preferentially water soluble, and therefore, will not affect downstream catalyst systems or WS1M ratings.

Chemical Description

KEM PR-4220 is a neutralising amine in hydrocarbon solvent.

Product Application

• KEM PR-4220 is particularly effective in pH control of crude unit overhead systems.

• Injection rate of 6 ppm is usually sufficient for chloride concentrations less than 100 ppm.

• KEM PR-4220 may be diluted with hydrocarbon condensate to compensate for pump capacity and should be injected ahead of the initial water condensation point.

• For maximum corrosion protection, KEM PR-4220 may be blended with oil-soluble, film-forming corrosion inhibitors.

• KEM PR-4220 should not be diluted with water.

Recommended Uses

KEM PR-4220 is effective for overhead systems of refinery units and petrochemical plants.

Features and Benefits

• KEM PR-4220 reduces low pH-induced corrosion in refinery and petrochemical processes.

• Particularly effective in pH control of overhead condenser systems.

• High neutralising efficiency.

• Extension of overhead systems life time.

• Does not impact WSIM ratings.

Material Compatibility

KEM PR-4220 contains no organic halides, heavy metals or other substances known to be harmful to process equipment or catalysts. KEM PR-4220 is non-corrosive and flammable.

Health Information

Avoid prolonged and repeated skin contact. In case of contact with skin or eyes, flush the exposed area with water for at least 15 minutes. Call a physician. Wear suitable protective clothing and chemical safety goggles. Please refer to Chemical Handling Data Sheet.

Storage/Handling

Keep away from heat, sparks and open flames. Keep containers closed to prevent product contamination and evaporation. Avoid breathing mists or vapors. Observe any warning labels on product container. Other normal precautions for process chemicals apply.
