General Information
KEM PR-4117 is a highly effective high temperature antifoulant for crude oils, residual crudes, and processed hydrocarbon feedstocks where asphaltenic, carbonaceous, and inorganic particulate matter are the basic fouling components. It has superior dispersant properties, which prevent suspended particulate from agglomerating and adhering to heat transfer surfaces throughout the unit.
KEM PR-4117 is typically used for fouling prevention in exchanger preheat trains of vacuum distillation units and FCC feed.

Chemical Description
KEM PR-4117 is a blend of dispersant based molecules.

Product Application
• KEM PR-4117 should be injected upstream of the fouling problem.
• Introduce far enough upstream to give good fluid mixing.
• Typical dose rates of KEM PR-4117 are 25-100 ppm depending on the specific application and fouling severity.

Features and Benefits
Superior dispersant properties. High thermal stability. Extends exchanger run lengths. Reduces cleaning costs.
Maintains throughput capacity. Maintains excellent heat transfer and hence reduces furnace fuel costs.

Material Compatibility
KEM PR-4117 is compatible with Teflon, Viton and most other elastomeric seals. In addition the product contains no organic halides, heavy metals or other substances known to be harmful to petrochemical processes or equipment.

Health Information
KEM PR-4117 has a low order of toxicity. 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. Please refer to Chemical Handling Data Sheet.

Storage/Handling
