Fouling Inhibitors

Fouling inhibitors stop or reduce fouling.

Deposits (fouling) appear at many places in the petrochemical industry. They result from undesired oxidation, polymerization, sedimentation and condensation processes and often occur in raw gas compressors, oil fractionation and gas separation units. Reactive compounds are ethylene, acetylene, propylene, butadiene, styrene or other unsaturated.  Trace amounts of oxygene or oxygene containing compounds promote the formation of gums and polymers. Fouling can be severe when monomers convert to polymers like the formation of „popcorn polymers“ from butadiene fouling. The most prevalent areas for polymerization fouling are ethylene and styrene plants.

We adapt the antifoulant treatment concepts individually to your system and combine the products in compliance with your tasks and requirements:

  • Radical catchers (scavengers)
  • Dispersants
  • Oxygen scavengers
  • Stabilizers
  • Antioxidants
  • Metal deactivators

Fouling in the raw gas compression (ethylene production) reduces the performance of compressors and may lead to vibration and a forced shutdown of the machine. Based on decades of experience Kurita developed a treatment concept especially for raw gas compressors which has been successfully established on the market. The applied antioxidants and antipolymerants are stable and do not cause any formation of hazardous nitrated dienes in the cold part of ethylene units.
