CO2 Separation Systems
CO2 Separation Systems Designed for Dependable Upgrading Performance
Nacelle provides CO2 separation systems for biogas and RNG facilities that need reliable upgrading performance, practical operation, and a stronger path to long-term gas quality results. We help customers evaluate, apply, and integrate separation systems so they support methane recovery, gas-to-spec performance, and steadier operation across the full facility.
Why CO2 Separation Matters
CO2 separation is central to biogas upgrading. It affects gas quality, methane recovery, operating stability, utility demand, and the overall performance of the upgrading system.
But separation performance depends on more than the separation technology itself. Pretreatment, pressure stability, moisture control, controls, and serviceability all influence how well the system performs over time.
Nacelle helps customers apply CO2 separation systems in a way that improves performance while reducing unnecessary operating friction.

Our Approach to CO2 Separation Systems
System Evaluation
We review gas composition, throughput goals, operating profile, and separation requirements to identify the right approach.
Integration and Facility Fit
A strong separation system must work as part of the broader process, not as an isolated package.
Performance Support
We help facilities improve existing separation performance, reduce instability, and address recurring recovery or gas-quality issues.
Common Questions
A CO2 separation system removes carbon dioxide from treated biogas to produce pipeline-quality renewable natural gas. The most common approaches use membranes, but the right configuration depends on feedstock, gas composition, and the specifications the project must meet.
Nacelle supports CO2 separation systems through equipment selection that matches real feed gas, integration with gas treatment and process equipment, and operations practices that protect long-term performance, methane recovery, and gas quality.
Yes. Nacelle works with facilities that need to improve, integrate, or troubleshoot existing CO2 separation systems — including projects where the system is no longer matching the way the facility is actually operating.
