Hello
Here is the situation : I have a group of chillers that cool a glycol solution. I have available two glycol storage tanks (about 50 cubic meters each) that are presently connected in parallel. Presently, all glycol streams are mixed in both tanks, ie cooled glycol from the chillers and hot glycol coming from the secondary circuit are mixed in the tanks.
I would like to know if I can use one tank for storing cooled glycol from the chillers, and the other tank for storing hot glycol from the secondary circuit. The primary pump would then pump hot glycol to the chillers and then to the cold storage tank. The secondary pump would then pump cold glycol to the heat exchangers and then to the hot glycol tank.
What would be the pro's and con's ?
