Reduce methane emissions and improve efficiency by converting high-bleed pneumatic controllers to instrument air systems. This approach supports regulatory compliance while lowering operating costs and fuel gas consumption.
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.
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
Convert high-bleed pneumatic controllers to low-bleed configurations and implement instrument air retrofits using LCO air compressor systems.
This approach:
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
