Title: Multi-stage vessel and separator/coalescer filter element

Abstract: The present invention relates to an apparatus for separating liquids and solids from a gas stream and simultaneously coalescing liquids from the gas stream. The apparatus includes a closed vessel having a longitudinally extending length, an initially open interior, an input port at an extent and an output port at an opposite extent thereof. There is a partition located within the vessel interior that divides the vessel interior into a first stage and a second stage. There is at least one opening in the partition. A separator/coalescer filter element is disposed within the vessel to sealingly extend from within the first stage through the opening into the second stage. There is a chevron-type seal or an O-ring seal between the filter element and the opening. The input port, vessel interior, separator/coalescer filter element and output port together define a flow passage within the apparatus, whereby the gas stream flows into the first stage through the input port and through the filter element hollow core, thereby filtering solids out of the gas stream, separating liquids from the gas stream, and pre-coalescing liquids in the gas stream. The gas stream then flows along the hollow core past the partition and back through the filter element into the second stage through a louvered impingement baffle, thereby coalescing liquids out of the gas stream, the gas stream then exiting the second stage through the outlet port. The louvered impingement baffle conditions the gas stream to create a scrubbing effect on any fine mist exiting the separator/coalescer filter element.
