Paratene™ D742 Vapour Phase Micro-Emulsion Degreaser

Paratene™ D742 is a blend of low toxicity surfactants and solvents in water intended to aid in the removal of hydrocarbon contaminants from process equipment. Paratene™ D742 water wets metal surfaces and loosely emulsifies hydrocarbons improving their removal by hot water or steam from process equipment and tanks. The solvents in Paratene™ D742 aid in the efficient removal of heavy hydrocarbons that cannot be removed by the action of steam or surfactants alone. Paratene™ D742 contains no inorganic components and is completely soluble in water.

Methods of Application

Paratene™ D742 can be added to hot water or steam at concentrations between 0.5 and 3%. The amount used will depend on the composition and amount of hydrocarbon deposit to be removed from the specific system. When added to steam Paratene™ D742 should be first diluted in water and added to the flowing steam as a mist. Please note that adding the product to the boiler feed water is ineffective.

Paratene™ D742 is compatible with alkaline additives such as trisodium phosphate and sodium hydroxide. These should be added in strongly sour systems to improve the removal of hydrogen sulfide.

Safety & Handling

Paratene™ D742 is non-flammable. It will cause irritation to the eyes and skin.
