Paratene™ D740
“Vapour Phase Aqueous Degreaser”

Technical Data Sheet

Description
Paratene™ D740 is a blend of low toxicity surfactants in water intended to aid in the removal of hydrocarbon contaminants from process equipment. Paratene™ D740 is used to reduce LELs and to control benzene, toluene and xylene emissions by forming a micro-emulsion that encapsulates the hydrocarbons in water. Paratene™ D740 will also act as a mild oxidizing agent to aid in the removal of hydrogen sulfide and pyrophoric iron compounds.

Paratene™ D740 water wets metal surfaces and loosely emulsifies hydrocarbons improving their removal by hot water or steam from process equipment and tanks.

Methods of Application
Paratene™ D740 can be added to hot water or steam at concentrations between 0.5 and 5%. The concentration used depends on the composition and amount of hydrocarbon to be removed. When added to saturated steam, Paratene™™ D740 should be first diluted in water and injected into the flowing steam as a mist. Simply adding the product to the boiler feed water is not effective, and is not recommended. Paratene™ D740 is compatible with alkaline additives such as trisodium phosphate and sodium hydroxide. These can be added in strongly sour systems to improve the removal of hydrogen sulfide.

Paratene™ D740 is also compatible with some mineral and organic acid solutions such as hydrochloric acid, Paratene™ M390, acetic, and formic acid.

In systems where H2S contamination is severe, Paratene™ M310 can be added to Paratene™ M310 to substantially increase the scavenging and removal of hydrogen sulphide.
