Instrument Air Systems - Reducing Pneumatic Methane Emissions

Global Power Technologies Aug 10, 2022 6:22:57 PM

Internationally, companies are pledging carbon neutral targets and taking action to eliminate devices or processes that have high Greenhouse Gas (GHG) emissions. In the North American oil and gas market, we are working with many clients to size, power, and compress air to replace instrument gas to avoid venting of methane on pneumatic devices.

EZAIR-CombinedClients have a dizzying array of choices on how to meet regulations or corporate environmental goals. Some common drivers include capital cost, operating cost, fuel consumption, emissions, simplicity of maintenance, site access and funding.

Once instrument air systems are installed, clients may benefit from tax credits, carbon credits, funding and/or improved corporate environment metrics to meet their strategic goals.  However, if not installed in a timely manner, the risks to operators can include carbon taxes, poor environmental perceptions or even suspended production.

Global Power Technologies (GPT) was the first company to design, engineer, and commission Instrument Air systems in Canada for an off-grid multi-well pad application. Since that time, GPT has continued to improve upon Instrument Air systems, implementing new features to allow for ease of operation while significantly reducing system costs.

GPT’s EZ-AIR Instrument Gas to Air Systems have been designed to eliminate pneumatic venting methane (CH4) emissions by using natural gas as a clean fuel source to generate electricity and/or compressed air efficiently and reliably.

EZ-AIR Systems Feature:

  • 99%+ methane elimination
  • Extremely low emissions and high efficiency
  • Low maintenance and mechanic-maintainable
  • Proven, reliable technology
  • Integrated air dryer
  • Flexible fuel options
  • Low noise output
  • Glycol heat trace available
  • Full remote monitoring from anywhere in the world
  • Cold start
  • Full enclosure, reach-in, or open skid models available
  • EZ Skid system configurable to accommodate existing or future site footprint

One key feature of the EZ-AIR System is the simple fact it’s mechanic maintainable. Your trained team or trained local service team can perform the simple 4-hour maintenance scheduled every 6–12 months depending on usage – And GPT is available to perform the service, if needed.

Competitive technologies, like Stirling engine-based systems, claim zero maintenance when in fact these systems require specialized engineers to check and service the unit. Bringing specialists on-site or removing and returning a system of this size is not only time-consuming, but very expensive.

When evaluating power generation options to drive an off-grid instrument air system, it’s important to choose a system with the greatest efficiency and lowest emissions. After all, these systems are installed with a goal to lower emissions. GPT’s natural gas and propane internal combustion engines (M-Series) are at least 40% more efficient, and up to 62% more efficient, in comparison to Stirling-based systems. The efficiency gain translates directly to lower emissions – rewarding you with 40-62% lower GHG emissions. Newer technology is not always better for the environment, so it pays to evaluate efficiency and emissions of the combined power and instrument air offerings.

All GPT systems are designed and manufactured in Canada with technicians and support teams located in both Canada and the USA – Easy. Maintainable. Efficient.
