Antifoulant Chemical Treatment

Thermoflo* high-temperature antifoulant chemical treatment

Thermoflo is a multi-component, oil-soluble antifoulant that combines a high-temperature dispersant and a coke inhibitor. This formulation effectively minimizes organic and inorganic material deposition on heat transfer surfaces, such as coke, sludge, corrosion productions, polymers, and catalyst fines.

Veolia’s antifoulant chemical treatment consists of dispersants (high and low temperature stable, organic and inorganic fouling), polymerization inhibitors (free-radical, condensation), metal coordinators/deactivators and various corrosion inhibitors that exhibit dispersant properties.

• Dispersants – designed to limit the particle size of solids in the system.
• Corrosion Inhibitors – designed to minimize the contact between the metal surface and the corrosive fluid to minimize the formation and deposition of corrosion products in the system. 
• Polymerization Inhibitors – "free radical" polymerization inhibitors are designed to react immediately with any radical formed in the system to form a new "stable" molecule which will no longer contribute to the propagation reactions. "non-free radical" polymerization inhibitors reduce the condensation polymerization reactions of carboxylic acids and some of the nitrogen compounds. 
• Metal Coordinators – modify the metal ions by complexing, this reducing the catalytic activity of the metal, so that inhibition of polymerization reactions is minimized.
