E. Glycol as an anti- freeze for ice water.
E. Glycol as an anti- freeze for ice water.
(OP)
hi friends,
we are commisioning a new refrigiration plant to form ice water using ammonia as a refrigerant. we have chosen to use ethylene glycol as an anti freeze. the ice water basin is 105m3. how much ethylene glycol do i need since i have never used it. is ther a better alternative?can someone help.
thanks

RE: E. Glycol as an anti- freeze for ice water.
I don't know your location, your regulations/codes, and what you are using the ice water for. If there is going to be any possibility of contaminating any foods for human consumption you would be far wiser to employ Propylene Glycol (PG) -which I consider to be a better anti-freeze - which is approved for food-grade uses.
For figuring out what concentration of aqueous PG to employ in your application go to:

I’m not going to do the simple math for you and identify how much you need. As a Chemical Engineer you should be more than qualified for that task.
I hope this helps.

am very gratefull for your help. actually am using the ice water in drying of bakers yeast in the dryers. propylene glycol would be the best alternative since its food grade.
