Antifoulant DOA144（Petroflo 20Y114 Replacement）is a water based, dispersant type antifoulant. It is designed to control hydrocarbon oil fouling and polymer fouling in petrochemical plant aqueous process equipment. Hydrocarbon oil and polymer fouling of dilution steam generators is reduced by product application. This product will reduce carbonyl polymer fouling of caustic scrub-bers and benzene strippers. The dispersant keeps hydrocarbon oils and carbonyl polymers from agglomerating, thus minimizing deposition on process equipment.
