Abstract From the Canadian patent

This application is directed to an apparatus for separating liquid droplets from a gas. The apparatus comprises interior and exterior curved walls which define an elongate chamber of generally uniform part-annular cross-section. There are inlet and outlet passages opening into the chamber and each of these is elongated in a direction longitudinally of the chamber and through which gas may flow into, around and from the chamber in a stream having little or no movement in a longitudinal direction. The exterior wall is provided with slits extending lengthwise of the chamber through which liquid carried by the gas may pass therefrom as the gas flows around the annular chamber.
