Anti-clogging agents are chemicals that are used to prevent clogging in a facility.
Clogging is a general term for unwanted sedimentation. Polymerization is a type of clogging. Another type of clogging involves the formation of salt in refineries. Polymerization is the release of monomer molecules and the formation of a gum-like substance. This phenomenon is harmful to towers and heat exchangers and causes their poor performance.
Anti-fouling compounds include dispersants (a substance that does not allow the polymer to accumulate and reduce the polymerization reaction), metal inactivators, retarders, anti-foulers, and anti-polymers.
These compounds are used for a wide range of clogging problems (listed below) and increase operating costs, reduce output current, degrade product quality and reduce equipment life:
Unwanted polymerization that clogs process units
Clogging of process flows due to sludge, bitumen, polymer or fine particles in raw materials
Corrosion and sediment formation in sensitive equipment
Salt deposits in refinery heat exchangers
Formation of unwanted activated metal surfaces after cleaning
