ANTIFREEZE RECYCLING IMPROVED WITH TRAMFLOC® 861 SERIES OILY EMULSION BREAKERS
Tramfloc, Inc. is pleased to offer a special reagent to break
out oily debris from used antifreeze solutions.
Tramfloc® 861, 861A, 861B and 876 products are amine blends especially formulated
to release the emulsified oil often present in used antifreeze solutions. They
are collected by independent antifreeze recycling companies all over the country
and world. The recyclers reconstitute the used antifreeze with new reagents
and offer the automotive repair trade a first quality product which helps our
environment. The recycling facility is challenged by the impurities which have
become part of the glycol solution.
The spent coolants contain oil, foreign matter, heavy metals, excess chlorides and suspended solids (rag layer). The contaminants should be removed so that the reclaimed antifreeze solution has a suitable technical and economic resale value. Rather than invest in capital intensive membrane systems, recyclers are treating their glycol batches with one of the above breakers. They have been designed to be functional in the environments of both ethylene and propylene glycol solutions with their unique polar characteristics.
Treating a batch of used antifreeze solution with 1000-5000
ppm of the above mentioned breakers is usually able to allow the tramp and emulsified
oil and solids to either rise to the top of the batch treatment tank or precipitate
as underflow to the bottom of the tank. Professional recyclers often install
conical tanks of 1,000 to 10,000 gallons in
capacity to reclaim the glycol-water mixtures. When the rag layer floats and
that is not desirable in the operation scheme of the recycling plant, the suspended
and floating solids may often be dropped to the bottom of the tank by means
of the application of one of the Tramfloc® 100 Series Bridger Flocculants.
They are designed to agglomerate the rag layer and cause it to precipitate to
the bottom of the treatment tank for non hazardous disposal.
The clarifier water produced in the batch tank by the activity of the Tramfloc® 861 Series products can be further recycled or sent to the POTW without further treatment. The supernatant quality is usually quite high when the emulsion breaking process has been performed effectively.
Any spent antifreeze or waste oil processing company which needs to simplify its treatment methods, improve oil release and reduce the reagent expense should evaluate samples of the Tramfloc chemistry for suitability in each recycler's operation. Contact Tramfloc, Inc. at water@tramfloc.com or 800-613-6803 for samples and to discuss your individual recycling operation's chemistry applications.
Glycols and water are very miscible and are common fluids used and
stored in many industrial facilities. When oil contaminates the glycol/water
mixture, emulsification often occurs and will produce a stable emulsion which
cannot be recycled without further treatment to break the emulsion.
We have determined that a special amine blend, Tramfloc® 861, has efficacy in
breaking the oil out of the stable emulsion. The released oil is usually clean
and of high quality for further processing and recycling. The remaining glycol
solution will normally contain a very low concentration of oil. The solution
can then be recycled or reprocessed.
Treatment rates range from 0.10-1.0% and all types of fats, oils and greases
have yielded to the Tramfloc® 861 treatment modality. Samples for bench testing
are available upon request by contacting Tramfloc, Inc.
