About GraniteFuel Engineering

Complete Biogas Upgrading Systems

Here at GraniteFuel, our team is an expert at every stage of biogas upgrading, offering both complete, integrated systems and custom-engineered solutions to clients across North America. The company originated as a fuel gas conditioning team at DCL International Inc—the well-known catalyst and aftertreatment expert—but we soon became a separate entity. The GraniteFuel brand is growing exponentially in energy reclamation—extracting value from waste products. We specialize in the design, engineering, and manufacture of biogas upgrading technology for wastewater treatment plants (WWTP), landfills, and agricultural waste. This focus promotes environmentally friendly practices, while turning a waste product into a valuable revenue stream. With growing public interest in renewable energy practices, turning your waste into biogas offers a multi-faceted return on investment (ROI). Financial gain from generating energy from a waste product comes with valuable green credentials that can improve your public image.

Complete Solutions For High-Efficiency RNG Upgrading

GraniteFuel Engineering has commissioned numerous gas conditioning and upgrading systems across North America that continue to produce ever-increasing volumes of renewable natural gas. These installations demonstrate our commitment to innovation, practical engineering, and sustainable energy development through proven field performance and in-house manufacturing expertise.

GraniteFuel designs, develops, and builds complete biogas and renewable natural gas (RNG) systems at our five manufacturing and assembly facilities located across Texas and Ontario. Each system is engineered for durability, process efficiency, and long-term reliability, providing operators with fully integrated solutions that transform raw biogas into clean, high-value renewable fuel. From moisture removal and contaminant control to compression, separation, and polishing, every GraniteFuel system is built to work seamlessly together as part of a unified, modular platform. Whether for agricultural digesters, wastewater treatment plants, or landfill gas projects, GraniteFuel systems deliver consistent performance, simplified operation, and proven results in the field.

All GraniteFuel biogas conditioning and RNG upgrading systems are engineered, fabricated, and tested in-house to maintain the highest standards of quality, integration, and safety.

Biogas Conditioning Solutions

GraniteFuel’s Biogas Conditioning Solutions prepare raw biogas for reliable upgrading and utilization. These systems remove moisture, hydrogen sulfide, ammonia, siloxanes, and oxygen to protect downstream equipment and ensure consistent gas quality. Each unit is engineered for continuous-duty performance under variable site conditions, enabling safe, stable operation across agricultural digesters, wastewater treatment plants, and landfill gas recovery facilities. Together, these conditioning systems form the foundation for efficient and high-quality renewable natural gas (RNG) production.

Engine-Out Emissions Guaranteed

GraniteFuel is a leader in the engineering of biogas conditioning systems. As part of the DCL Technology Group, GraniteFuel can additionally provide you with an engine exhaust emission control systems together with a tailpipe emissions guarantee.

The installation of emission control devices on biogas engines is becoming increasingly common. Just as an engine will suffer with increased biogas contaminants, so too will the emission control system. GraniteFuel provides high efficiency biogas conditioning systems to process raw gas to levels ideal for optimum engine and emissions system performance at the lowest operating cost.

The single-most common cause of premature emission control system failure is siloxane poisoning. GraniteFuel’s temperature swing adsorption system provides siloxane removal at efficiencies high enough to allow the use of oxidation, 3-way catalyst and SCR systems in the engine or turbine exhaust.

As part of the DCL Technology Group, GraniteFuel can provide a tailpipe emissions guarantee when the GraniteFuel SRS is used with DCL & AeriNOx emission control technologies.
