Abstract

Degassers, degassing systems, and methods of using degassers to remove gas molecules entrapped or dissolved in a processing liquid. The degasser has a vacuum chamber with one or more walls; one or multiple inlets and one or multiple outlets through which the liquid is respectively passed into and out of the vacuum chamber, the inlet(s) and the outlet(s) penetrating the one or more walls; one or multiple separators located inside the vacuum chamber and being pervious to the gas molecules but impervious to the liquid; at least one vacuum for applying through a vacuum port a pressure differential across the separator(s) to cause the gas molecules to leave the liquid and to permeate through the separator(s) thereby removing the entrapped or dissolved gas from the liquid; and optionally one or multiple feed lines in fluid communication with the inlet(s) and two or more than two separators.
