Liquid Carbonics Corp 1

Who ended up with the intellectual property of the Liquid Carbonics Corp?

I am particularly interested in a compound they called CT-90. Various formulations using this product were called RD 16 Cu, RD 16 Fe, RD 16 Cr, etc.

These compounds were very powerful chelating products that were originally developed for cleaning nuclear reactors. We attempted to used these compound in CTW with mixed results.
They completely cleaned equipment of Chromates and offered some protection for a short time.

The tests were abandoned when the test loops developed severe pitting.

Uncle Syd:

Liquid Carbonics Corp. was bought and paid for by Praxair.

Praxair is the inheritor of the Linde (air separation and industrial gases) dynasty that used to belong to Union Carbide (who had to liquidate a lot of their assets to pay for Bhopal & a lot of other mistakes). By acquiring Liquid Carbonic, Praxair assumed control of a lot of CO2 technology and markets that fitted in just fine with their industrial gases markets. Liquid Carbonic itself also dabbled in industrial gases in its prime.

Therefore, I think I am right in presuming that if you contact Praxair, you will find the final resting place of all the available Liquid Carbonic technology and know-how. I started my career with Liquid Carbonic and was there for my first 9 years. I had a lot of friends there and that's how I keep up with this stuff.

Good Luck.

Art,

Thanks for the information about Praxair. I will have to do a little calling as it is hard to get past the front desk at Praxair. I have a couple of markers to call in from a couple of the Linde people.

The CT 90 material was an excellent metal cleaner and inhibitor if maintained in the proper concentration. The problem was when we tried it in one of big cooling towers the concentration effects weren't know to us. The material cleaned many feet of pipe and all sorts of HE's, to bright metal. We though we had several problems licked, got rid of the residual Chromates and all the Fe deposits. When we got rid of the residual Chromates we allowed the MIC to run rampart. MIC wasn't even a consideration at the time as the deleterious effect of bacteria wasn't known and in our case was no problem as we used Chromates as the primary corrosion inhibitor in CTW. It turned out that the pristine surface of the metal was a prime candidate for the MIC attack. This coupled with the fact that our concentrations of CT 90 were too high caused us to come to the wrong conclusions about the corrosion protection offered by the CT 90.

The reason I was looking for information is that I have a very delicate metal cleaning job that nothing else tried will do the job and this material has achieved excellent results on several previous occasions.
