Environmental stewardship and regulatory compliance

摘要

A case-study using Norriseal Series 2200 control valves equipped with Tritex II electric actuators from Norriseal WellMark. All pneumatic controllers vent a small amount of gas to the atmosphere after it is used to energize a dump or control valve. However, with constant devices, the bleed gas - the gas that leaks to the atmosphere between dump cycles - is much higher in volume and poses the greatest risk of exceeding regulatory limits on greenhouse gases. The U.S. EPA has mandated that companies operating in the Oil and Natural Gas Sector (who typically use natural gas to power pneumatic controllers) must use controllers with bleed rates no greater than 6.0 scfh.
