Product Description

What is the Ammongas biogas upgrading plants process?

Ammongas: Biogas Upgrading plantsThe transformation from organic waste material into biogas is executed by microorganisms in large tanks. The succeeding purification process in an Ammongas upgrading plant cleanses the raw gas directly (meaning no pre-cleansing is needed) with a watery solution of an alkaline liquid that dissolves, thus, removes the acidic pollutants in the gas (CO2 and hydrogen sulphide and more).

After this, the gas is compressed, dried and measured before it is delivered to the pipes from a natural gas company. At the regeneration of the used cleaning liquid, heat is used to separate CO2 from the liquid. The heat however, can be reused afterwards to keep the biogas reactors warm, or as a supplement to district heating, which gives an additional advantage in the profit and loss account.

Since the power consumption for the Ammongas process is only 0,1kWh/m3 biogas the net energy consumption is very low. At the same time the methane loss is below 0,04%, which not only saves energy, but also works in favour for climate balance. Finally, a plant from Ammongas is stable, has a high operational up-time, low demand for service and a significant lifetime for the components, meaning you, as a customer, are ensured easy operations and optimal income for both the short and long term.



What are the benefits of these biogas upgrading plants?

Ammongas: Biogas Upgrading plantThe advantages of transforming suited organic waste matter into upgraded biogas are both numerous and significant:

  • Upgraded biogas can play a key part in the green transition through ensuring the energy flow to both industry and consumers, even when the sun isn’t shining, and there is no wind.
  • The treatment of livestock waste in a biogas facility means that there is not only a financial gain by selling the gas, but also that the manure is subsequently more homogenous.
  • Instead of having waste energy rotting on the ground or in the slurry tank, the transformation into methane makes the energy useful; in addition to that, an equivalent amount of fossil energy can be saved.
  • During the subsequent decomposition of the waste material, methane and laughing gas etc. are formed that are much more potent greenhouse gasses than CO2. So the combined environmental gain is 3-4 times bigger than the direct replacement of the fossil fuel. (the loss of methane in an Ammongas plant is all the way down to 0,04%, lowest on the market)



Efficient biogas upgrading plants by Ammongas

Ammongas does not manufacture the biogas plant itself, but the plant that subsequently ensures an effective and thorough cleaning of the gas. Since the process is completed without pressure and without the need for pre-cleansing of the gas, the need for service and maintenance at later stages are minimalised. The pressure-less operation means it is possible to construct larger plants without corresponding price increases. Current reference list goes from 300 to 3000m3/h, but the plants can easily be adapted for larger output if there is a need.

No matter the size, plants are delivered on prefabricated frames, hereby ensuring that all parts are easily accessible for both service and operation. We can deliver to both new and existing biogas plants.

If your requirements deviate from the above mentioned, please contact us and we will see if we can find a solution.

After the initial start-up, there is a run-in period, where we ensure that the plant is operating according to the specification. We also offer a service agreement, securing the plant’s optimal long-term operation productivity.
