GraniteFuel – Biogas Upgrading
Complete Biogas Conditioning Systems
GraniteFuel Engineering designs and develops innovative fuel conditioning systems for industrial engines used on waste to energy (WtE) sites fueled by wellhead, landfill or digester gas at landfills or waste water treatment facilities. GraniteFuel’s unique fuel conditioning solutions are custom designed for each application to provide consistent and efficient reduction of fuel contaminants. GraniteFuel systems have been developed to outlast any other solution on the market while maintaining low operating expenses to provide long-term, cost-effective fuel conditioning.
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.CO2/CH4 separation skids are designed and manufactured to meet application requirements. Appropriate gas cooling, polishing, and monitoring ensure compliant RNG for CNG or pipeline injection. Systems can be designed in an open frame or containerized for climate control as required by the customer.
Technology Strengths, Weaknesses and Critical Indicators
Anaerobic Digester Associated Technology:
NOTE: There are several technology types that are used as part of an integrated manure management system that includes an anaerobic digester and are not applicable to manure management in other cases. The impact of these technologies on the critical indicators are represented as those of an entire anaerobic digester system.
- Long usable life and can be run reliably
- Creates energy and generates environmental credits
- Requires proper preparation of the feedstock
- Requires other technologies for energy utilization
- Requires other technologies for digestate handling
- Proper feeding & system monitoring is required to avoid system downtime
- Proven technology for odor control, GHG reduction and pathogen reduction
GraniteFuel has recently been added to the Newtrient catalog. Newtrient will continue to work with GraniteFuel to further refine the cost and performance information on their technologies and services. Newtrient will update this entry as more information becomes available and as new commercial dairy installations come online. Biogas upgrading technology: Produces renewable natural gas (RNG) by removing carbon dioxide, hydrogen sulfide, nitrogen, oxygen and water vapor from biogas Includes technologies such as membrane separation, pressure swing absorption and water scrubbing Used to treat biogas from an anaerobic digester Most systems are technically complex Interconnection to the national gas infrastructure typically requires large systems and proximity to large volume gas lines This technology is not evaluated on its own, the NEAT Matrix for this technology is based on results from an entire Anaerobic Digestion system.
