Control valves + electric actuators enable an increase in production capacity
A Denver-based operator discovered a large source of emissions attributed to pneumatically operated valves in their Central Processing Facility and gas lift injection applications. The operator began replacing 150 pneumatically controlled valves in their gas lift injection application with Norriseal Series 2200 control valves equipped with Tritex II™ electric actuators which led to zero emissions and greatly improved operations. Compared to previous pneumatic valves, the company is preventing approximately 2000 mcf per year in fugitive emissions, with a current annual value of $1,966,800. The reduction in emissions has resulted in an increase in the state-regulated production capacity, potentially adding 10% production. Not only were emissions saved by preventing the release of bleed gas into the atmosphere, it was found that personnel safety, especially in closed environments, was an added benefit as well.
