Can somebody describe a refrigeration circuit in a bioethanol plant?

- refrigeration cylce through the bioethanol plant installations (where and
why its needed?).

- refrigeration equipment (for the same factory).
thank you all in advantage.

Re: Refrigeration circuit in a bioethanol plant

I suspect you would be referring to refrigeration of fermentation vessels. Yeast (which I suspect would be the organism used for the fermentation stage) works best at a certain temperature, which is a balance of yeast cell death rate, and fermentation rate if i recall correctly. The fermentation process itself is an exothermic (producing heat) process, and so a refrigeration system would be used to keep the fermenters at the optimal temperature.

Alternatively, you may be referring to the cooling system in the distillation stage; although this is unlikely to be refridgerated (rather, they would use cooling water).

Hope this gives you a starting point.
