Abstract
Abstract A porous coalescing filter element of conical configuration is disposed within a substantially cylindrical filter housing such that the area between the element and the wall increases in the direction of the primary phase flow to keep the annular velocity substantially constant or decreasing in the direction of primary fluid flow. The element may be manufactured with a round end and tapered walls terminating to a pointed apex, but is more preferably manufactured and secured within the filter housing using flat end caps on both ends. The filter element may be vacuum formed, or manufactured from media in a flat sheet form, which may be pleated if desired.

A porous coalescing filter element consisting of a coalescing media of conical shape which separates gas bubbles dispersed in a first liquid stream from a second liquid by means of flowing the gas liquid mixture through the filter media in a direction from the inside to the outside of the element, and allowing the gas bubbles while within the media to come in contact with the filter media in the element causing the bubbles to coalesce with other gas bubbles which have also come in contact with the filter media to form larger gas bubbles which eventually emerge on the outside of the element and are thus separated from the second liquid.
