Process equipment fouling in refineries is an ongoing, tenacious, and extremely costly problem. Severe economic and operational penalties related to fouling include inefficient heat transfer, corrosion, reduced reliability and processing flexibility, excessive maintenance requirements, throughput limitations, equipment damage, and significant safety and environmental concerns.
For more than 30 years, Veolia has developed fouling reduction programs by analyzing system operating performance and mechanical configuration, root cause analysis, and antifoulant product testing on blended crude oil samples provided by the refiner.
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.
