Abstract:
A process for reducing undesirable dissolved gasses in a liquid and adding desirable gasses to the liquid, comprising the steps of:providing a hollow tank with a liquid inlet, a liquid outlet, a scrubbing gas inlet, a scrubbing gas outlet, and a desired liquid level in the tank; connecting a source of liquid to the liquid inlet, the liquid having a given pressure; providing a scrubbing gas supply line supplying a flow of scrubbing gas to the scrubbing gas inlet, the scrubbing gas having a pressure higher than said given pressure; providing a canister on the scrubbing gas supply line, the canister containing at least one desirable additive for the liquid, the additive in a form that vaporizes into the scrubbing gas; providing a scrubbing gas flow valve on the scrubbing gas outlet that releases scrubbing gas from the tank at a variable rate; and, stabilizing the liquid level in the tank around the desired liquid level by variably venting scrubbing gas from the tank via the scrubbing gas flow valve, without controlling a liquid pump; whereby the process reduces undesirable dissolved gasses in a liquid in the tank, and adds desirable gasses to the liquid, without the need to control a liquid pump.
