ABSTRACT:
Systems and related methods for separating liquids and particulate from a flowing gas stream include a separation vessel containing a liquid injector, an impingement separator or a helical impingement separator, and a waste liquid recovery tank. Separated liquid and particulate collect in a sump, flow into a recovery tank, and may be filtered in a side stream duplex filter circuit for return into the recovery tank and re-injection into the separation vessel. The helical separator element has outwardly extending helical fins that form helical gas channels. The interior of the channels forms a rounded radius and opposing vertical edges of the channels include chamfers. The lower end of the helical separator element forms a concave, generally conical surface. The helical fins form a first impingement separator and the chamfers form a second vane-type impingement separator, such that particulate and liquids may be removed from the gas stream at varying flow rates and liquid/particulate densities.
