Abstract

A deaeration apparatus for removing entrained gases from liquids, comprising a degas vessel, which is baffled to enhance degasification. As gas removed from the liquid collects in an upper part of the degas vessel, the pressure in the vessel increases, lowering the liquid level therein. A sensing mechanism provides a liquid level signal to a controller which opens a valve at a vent port at the upper portion of the degas vessel when a predetermined liquid level is reached, whereby gas is vented from the vessel. The gas venting causes pressure in the degas vessel to decrease, thereby allowing the liquid level to again rise to a selected liquid level at which the level sensing mechanism signal causes the controller to close the vent valve.
