Device and method for degassing a liquid

摘要

Method and device for degassing a liquid of a substantially closed liquid circulation system at a working pressure. The method comprises passing at least a partial flow of the liquid through a restriction into a chamber in which a degassing pressure is maintained, the degassing pressure being higher than atmospheric pressure and lower than the working pressure, separating gas withdrawn from the partial flow of liquid from the partial flow, removing the gas from the chamber, and pumping the degassed partial flow of the liquid back into the substantially closed circulation system. The restriction comprises a nozzle, and the step of passing at least the partial flow of the liquid through the restriction into the chamber comprises spraying at least the partial flow of the liquid through the nozzle into the chamber for obtaining a jet and/or mist of the liquid in the chamber.
