The Mathena™ shale-gas separator, field-tested for air volumes of 2,000 to 6,000 cubic feet, parts shale cuttings from gas in air drilling operations.
The patented Mathena™ shale-gas separator separates shale cuttings from gas during air drilling operations. Dust from air drilling is suppressed by water flow through a dust eliminator system, which is affixed upstream of the separator on the flow line.
As air, shale cuttings and gas enter the unit, gas is directed to the top of the vessel through the vent line to the igniter, while heavier materials, including water and cuttings, are discharged through the bottom of the unit by a jet hopper system to a haul-off pit. It includes a float indicator, horn and flashing light warning system to notify personnel of fluid levels.
The Mathena™ shale-gas separator features an internal U-tube with an external valve for fluid bypass when water is encountered while drilling. A removable internal wear plate is positioned near the tangential spin inlet to provide longer lasting wear.
