Driving Emissions Reduction and Efficiency in Pneumatic Systems

June 10, 2026

The Challenge

High-bleed pneumatic controllers are widely used to regulate process variables such as temperature, pressure, and liquid levels. Many of these devices rely on natural gas, resulting in continuous methane emissions during operation.

Controllers with bleed rates greater than 6 scfh contribute significantly to greenhouse gas emissions. In addition, poorly maintained devices may vent gas continuously, increasing environmental impact and creating compliance challenges.
The Solution

The Solution

Convert high-bleed pneumatic controllers to low-bleed configurations and implement instrument air retrofits using LCO air compressor systems.  

This approach:  
  • Replaces natural gas as the operating medium with instrument air
  • Reduces bleed rates to below 6 scfh
  • Eliminates emissions from active pneumatic control loops
  • Reduces on-site air demand through optimized pneumatic retrofits

The Value

  • Eliminates methane emissions from pneumatic controllers
  • Supports environmental regulatory compliance
  • Reduces operational and fuel gas costs
  • Improves overall operational efficiency
  • Enables a clear return on investment through emissions reduction and cost savings
