Greenlane – Gas Upgrading System

Working Across the Americas with Unrivalled Expertise in Renewable Natural Gas Upgrading.

Company Description:

Greenlane Biogas was formed in November 2008 under the brand name Chesterfield Biogas (CBG), following the signing of a co-operation agreement with Greenlane® Biogas, the world leader in biogas upgrading. It gave exclusive rights to market, manufacture and maintain Greenlane® equipment in the UK and Eire and saw the UK’s first biogas upgrader supplying biomethane to the national grid installed at a Thames Water site in Didcot in 2010.

Technology Description:

The technology employed is efficient and environmentally friendly, processing and purifying the raw biogas produced from wastewater treatment and the anaerobic digestion of a wide range of organic waste materials, including food waste. When upgraded, the resulting biomethane (or renewable natural gas) has very similar properties to the natural gas used in gas networks or as a vehicle fuel. Many Greenlane projects have gas-to-grid or pipeline connection as their objective.

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
  Greenlane is an international company that has sales offices in British Columbia and the United States. They offer several types of biogas upgrading systems including water scrubbing, PSA and membrane technology. The Greenlane systems have been installed on multiple sites in the US including several dairy related projects. The systems are usually containerized and installed as part of an anaerobic digestion system that is producing RNG. There are known compressor related issues that have affected up-time and performance with several of the Greenlane water scrubbing units in the field. Greenlane has indicated they have resolved these issues on the existing units and modified their design to avoid them in the future.
