degasifier 1

What happens if the air used for blowers in degasifiers for removing CO2 is feeded from outside and has a very low temperature (aprox. -20 degrees C)? I know that the solubility of gases in water decreases while increasing the temperature and decreasing pressure.

As you allude to Henry's Law the opposite is also true. As temperature decreases the solubility of dissolved gas increases.

Also depends on what you are degassing. If its water you will probably freeze up blowing -20 C air into it.

So you are saying that heating up the air it's a solution? I am degassing water indeed.

 

[dcasto]

to degassify water, you need to use a packed column working under a vacuum.

The term "degasifier" has been used to refer to two types of water treatment equipment: a vacuum degasifier and a "forced Draft degasifier" (also called a decarbonator).

Anyway, to answer your original question. A continuous flow of water through the unit will not result in freezing. The air flow is usually sized at 3 SCFM / GPM of water. Assuming inlet water temperature of 60 ^F, there will be some cooling, but not enough to result in freezing. Hopefully, the supplier of the degasifier provided a mist extractor at the top vent to prevent water carry-over. If not then you will see ice accumulating on the outside of the tank.
