Abstract
Apparatus for separating a liquid from a gas includes a cylindrical separator element disposed in a sealed housing. The separator element includes a helical ramp wrapped around a cylindrical column both of which are disposed in a hollow cylindrical shell. The ramp, column and shell cooperate to define a helical passage through which a liquid-gas mixture is constrained to pass between an inlet and outlet at opposing ends of the separator element. A liquid-gas mixture entering the separator element is imparted a swirling motion as it passes through the helical passage within the separator element. Liquid entrained in the mixture migrates radially outward within the separator element and passes through the permeable shell. The separated liquid drains by force of gravity to a sump area defined by the sealed housing from where it can be drained for re-use.
