BioCNG – Gas Upgrading System

A Tetra Tech Company

Company Description:

BioCNG, LLC is the co-inventor of the BioCNG™ biogas conditioning system, which economically produces biogas-based fuel for compressed natural gas (CNG) vehicles. The innovative system is operating successfully, running several small fleets on CNG produced from landfill gas, wastewater treatment plant digesters, and anaerobic food waste digester biogas.

 

While the standard BioCNG™ unit sizes use 50, 100, 200 and 400 scfm, systems can process 20 to 2000 scfm of biogas to produce 100 to 10,000 gasoline gallon equivalents (GGE) of BioCNG per day. The fuel can be used directly or mixed with natural gas to produce a blended vehicle fuel. The modular BioCNG system can easily be expanded to respond to increased gas production. After cleaning and conditioning, BioCNG™ fuel meets SAE J 1616 and engine manufacturers’ fuel specifications and can be used without modification in the same engines as natural gas-CNG.

Technology Description:

The BioCNG™ system offers a simple and effective technology for producing CNG vehicle fuel.  Biogas is piped to the BioCNG™ System from a landfill or anaerobic digester. Then hydrogen sulfide, moisture, siloxanes, volatile organic compounds and carbon dioxide are removed. Product gas is piped to a vehicle fueling system for use as fuel in CNG vehicles.

System components

If inlet biogas quality meets certain standards, BioCNG guarantees that the biogas produced meets SAE J1616 vehicle fuel quality standards. Production costs range from $0.65 to $1.15 for a gallon of gasoline equivalent (GGE), with the potential for renewable fuel credits (RIN).

The system can be supplemented or run in parallel with natural gas and it can be integrated with existing cogeneration systems. Vehicle fueling systems, (compression, storage, and fuel dispensers) can be customer-supplied or included with the BioCNG™ system.

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

Newtrient Comments/Opinions:

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
