Maximize NGL Value
Cryogenic level NGL recoveries capturing 60% of C2 and 95% C3+, keeping NGL’s in gaseous form for downstream monetization.
Minimize Emissions
Reducing up to 75% VOC emissions, and 8% CO2 emissions upstream of engine catalyst.
Maximize Throughput
Residue quality fuel gas minimizes engine derating (up to 9%) to maximize gathering station throughput and fee-based revenue.
Your Fast Track to Cryogenic-Quality NGL Recovery and Lean Fuel Gas for Gas Fired Engines at Compressor Stations
Generate More NGL Revenue, Maximize Compressor Station Capacity, Reduce Costs, and Reduce Emissions
The MaCH4™ NGL Recovery Solution is a proven, robust, and energy efficient gas separation solution developed and patented by ColdStream Energy. The MaCH4 delivers cryogenic-like recovery of NGLs to provide residue line quality gas without the expense of constructing a residue line. MaCH4 is a compact design with no rotating components or chemicals required to lower operating costs. A simple and economically compelling solution for maximizing NGL value, minimizing VOC emissions, and maximizing fee-based revenue for producers and gatherers, while also maximizing the efficiency and runtime of engines and respective compressors.
First Commercial Units (Up to 8,250 HP*)
From Pilot to Profits! Commercial Units available to Deliver Lean Fuel Gas to Support Up to 8,250 HP and Solve Your Challenges Burning Rich Gas.
*All data based on 1,310 BTU HHV field gas; 1,080 BTU HHV fuel gas; lean burn engines; and 5-year average EIA NGL pricing. Engine fuel gas flow rate and associated gathering station HP will vary based on field gas composition and BTU HHV.

Benefits
- Generate More NGL Revenue
MaCH4 units deliver cryogenic-like performance recovering 60% C2 and 95% C3+ heavy hydrocarbons on site, separating valuable NGLs, and boosting profits. Stop combusting money! - Maximize Compressor Station Capacity
MaCH4 units supply consistent fuel gas to maximize engine performance and throughput. By improving engine and compressor efficiency, adding a MaCH4 can increase compression capacity without installing new compressors. - Reduce Operating Costs
Engines burning lean fuel gas supplied by MaCH4 units not only operate more efficiently, but they also operate cleaner and require less downtime for maintenance and repair. Longer service intervals and less frequent downtime translates into lower long-term cost of ownership. - Reduce Emissions, Simplify Permitting
Using the pipeline quality fuel gas delivered by MaCH4 technology means your generating the lowest VOC emissions possible, improving your ability to keep facility Potential to Emit (PTE) below Major Source emissions thresholds to avoid time-consuming and costly Title V Operating Permits to maximize revenue generating compression on site.
