ABSTRACT:
A plenum based high-pressure blowback gas delivery system is provided. The system includes a filter vessel, divided into two portions, including and inlet and outlet for fluid. The system further includes a plurality of filter elements to filter fluid flowing from the first vessel portion into the second vessel portion. In response to a pressure differential caused by accretion of particulate matter on the filter elements a uniform flow of high-pressure blowback gas is delivered to the filter elements via nozzles attached to plenums contained within the second vessel portion.
