Paratene™ D708 Water-Based Degreaser Concentrate & Coke Descalant

Paratene™ D708 is a specialized blend of surfactants and solvents designed to aid in the removal of hydrocarbon fouling from process equipment and vessels. Paratene™ D708 is a water-based alternative to solvent based degreasers, and was created to be a low toxicity, non-flammable and effective on even heavy hydrocarbon fouling. Paratene™ D708 is a concentrate and should be diluted prior to use. Paratene™ D708 contains special Wetting agents to improve the removal of coke, carbon, and soot from metal surfaces.

Features and Advantages

-  Excellent water wetting and solids carrying capacity.
-  Non-emulsifying – simplifies disposal, and some solutions may be re-used.
-  Water based.
-  Non-flammable.
-  Low toxicity.
-  Alkaline solution – reduces the release of H2S and the creation of polythionic acids. Non-damaging to coatings, paint, nylon and rubber.
-  Contains no inorganic phosphates
-  Excellent freeze/thaw stability
-  Excellent wetting and removal of soot, coke and carbon from metal and ceramic surfaces.

Methods of Application

Paratene™ D708 should be mixed with water, or alkaline solutions at concentrations ranging from 25 - 50 percent to form a cleaning solution. The blend has been designed with the ultrasonic process in mind; however, it can be applied using standard cleaning industry techniques including spraying, cascading, or circulating. 

Paratene™ D708 is an excellent cleaning agent for use with industrial ultrasonic baths. It must be diluted 1:1 with water prior to application to ensure best results. It improves penetration and removal on even the hardest hydrocarbon deposits and its low toxicity and moderate pH makes it compatible with most metals including aluminum. 

The cleaning solution is also effective when applied at temperatures ranging from 50 to 90°C and circulated for several hours until all of the hydrocarbons have been removed and carried in the cleaning solution. Circulation is then stopped and the cleaning solution stands idle to allow the hydrocarbons and solids to separate out of the solution. The hydrocarbons can be recovered and the remaining solution can be sent to a facility’s water treatment unit, to a disposal facility, or in some circumstances re-used. 

Where required, Paratene™ D708 can be combined with other Paratene™ products to satisfy site-specific degreasing challenges. Consult with the Clean Harbors laboratory to determine the best application for your problem.
