Dr Botte Through out a technical cookie in her interview that causes me reconsider the viability of the ACE unit to remediate ammonia in industrial waste streams.
First of all one has to know that 10,000 parts per million is equal to 1%.
Second is that the DEQ sets limits on waste returned to the environment and that the amounts are generally in the lower parts per million range in industrial waste water samples.
Now for the cookie.
In her discussion of removing ammonia from municipal waste water, Dr. Botte said :
“For a city as large as Columbus, there would have to be an investment in separating waste from kitchen and bath water. Some dilution is workable, but all that water is too much.”.
The statement indicated that as the ammonia is diluted more and more, the cell becomes less efficient until it doesn’t work . This is good for producing hydrogen on demand but bad for recovering ammonia from industrial waste water.
I can say that her ACE unit may work with some companies to get the level in compliance with DEQ. It depends on the other contaminants and chemical compatibility of the cell to the process.
We analyze for impurities in different process areas and the material of construction in contact with the process changes form unit to unit.
I can speculate on the operation of the ACE unit as a result of the interview. In My opinion the below would be a highly viable concept.

There is a good thing about the cell efficiency changing with concentration. It will allow the ACE unit to produce Hydrogen volumes that change with the power demand of a fuel cell in a house or a car. Anhydrous Ammonia would have to be the fuel stored.
I understand that water is needed in the process but not consumed. Given a container with a set volume of water in it and using the Anhydrous Ammonia to change the level would allow the concentration to be linearly controlled. I expect that this would be the way they could get Hydrogen on demand for various requirements.

It would be nice to get some feedback from anyone that may be interested in the technical side of the company.
