Constant volume and therefore constant flow rate apparatus is provided for removing bubbles of gas from a process liquid that is used in the manufacture of a product where the presence of such bubbles has a detrimental effect on the quality of the finished product. Gas bubbles are removed from a liquid by passing the liquid through a bubble coalescing baffle, in a generally upward direction, and into a chamber situated directly above the baffle, the chamber having an upward sloping upper surface, and a gas vent at the upper portion thereof, that is laterally displaced a substantial distance in the direction of liquid flow from the center of upward liquid flow, for the purpose of continuously venting gas bubbles that have separated from the liquid without allowing a significant volume of gas to accumulate in the chamber and without allowing the liquid to exit through the gas vent. The flow rate of liquid passing through the apparatus remains substantially constant primarily because the separated gas is vented before it can displace the liquid to any significant degree. After exiting from the baffle, the direction of the moving liquid is substantially reversed with respect to its generally upward direction through the baffle, before being permitted to pass out of the bubble removing apparatus, to thereby take advantage of the buoyancy forces on the rising coalesced bubbles for enhanced process liquid/gas bubble separation.
