Agra Energy – Biogas Conversion
Introducing cutting-edge technology into the renewable energy industry
Agra Energy has innovated a new compact-design for Gas-To-Liquid conversion processing. This means processing biogas via chemical-reaction that converts it into petroleum liquids. This downscaling of the technology marks an improvement that changes the scale and efficiency of making renewable fuels from any bio-gas feedstock. In practical terms, a moderate volume of waste-gas can be converted into 45 barrels per day of high-quality, cleaner fuels.
Agra Energy's MICRO Gas-To-Liquid (GTL) UNIT is prefabricated and transportable. Installed at a farm location, this unit will process the “feedstock methane” from a herd of dairy cows. The effluent-waste is converted into about 25 barrels per day diesel, naphtha and jet fuel products. It is on the scale of a highway transport truck and remotely operated. Their conversion process recycles its own by-products (water and heat) with negligible effects to the environment.Benefits to the dairyman are significant. Their operations are streamlined, expenses reduced, and economics improved. Pollution concerns, along with the accompanying regulatory issues, are significantly reduced. The methane-gas from “cattle operations” is captured and removed from the atmosphere. Soil deterioration and potential long-term groundwater issues are mitigated. The prolific farm-odors from dairy operations are greatly reduced. Also, a high-nutrient water is produced in the process for farm use as a fertilizer.
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
Agra Energy has recently been added to the Newtrient catalog. Newtrient will continue to work with Agra Energy 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.
