Ammongas – Biogas Upgrading

Company Description:

Ammongas is a Danish company founded in 2002 with more than 39 plants spread out over Northern Europe. The upgrading plants are designed and built by our dedicated engineers with focus on a mixture of sustainability and efficiency. The upgrading plants deliver a high concentration of methane that can be injected directly into the natural gas grid or be used for transport to the benefit of the environment. The plants are energy efficient and designed as compact systems with a minimal need for service.

Ammongas is part of a Biogas Alliance led by the Danish Trade Council in North America.

Technology Description:

Ammongas uses the well-known absorber-stripper system with amine for upgrading of biogas. The process has been used for many years in the oil and gas industry for removal of CO2, H2S other acidic gasses, and is known for being a robust and reliable system.

Ammongas’ absorption process is so efficient that the methane slip to the atmosphere is less than 0.05%. This means that the amount of methane gained is more than 99.95%.

Due to the efficient process a high concentration of methane in the separated biomethane stream of 99% is achieved. Furthermore, Ammongas’ amine upgrading can remove down to less than 50 ppm of CO2 in the biomethane stream, and thereby prepare the gas for liquefaction.

The robust technology and process of the upgrading process, results in low operational expenses, as well as a high up-time, with an average up-time of 99% including service.

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
