ABSTRACT:
This invention provides for reliable, long-life operation of fluid pressure responsive engines directly from raw natural gas at the wellhead by introducing a novel rotary dynamic contaminant filter system especially adapted for removing liquid and abrasive particle contaminants from the flow of natural gas under high pressure from the wellhead. Thus, a novel turbine type gas driven rotor in the gas flow stream has rotor blades slanted at an angle to the rotation axis to serve as a ramp for removal of contaminants as the flow of gas spirals upwardly from input to output ports. This dynamic filter employs the combined forces of gravity, centrifugal force and those imposed by interception with a contaminant flow ramp to encounter and remove a wide range of microscopic contaminants from the high pressure wellhead natural gas.
