Abstract From the Canadian patent

The specification describes a gas-liquid separator which is compartmentalized for eliminating high speed streams of gas-carrying liquid. These compartments in combination with anti-vortex and liquid flow path impeding means reduce the liquid flow speed and turbulence in the liquid to effect the separation of the gas from the liquid. The separator is provided with a liquid outlet and a separate venting means for the escape of the separated gas.
