How does Bio-Up® work

Biogas from digestion contains primarily of methane (CH4) and carbon dioxide (CO2), water vapour and small amounts of hydrogen sulfide (H2S). To upgrade biogas to biomethane, Bio-Up removes CO2, H2S and water. After quality control (including possible impoverishment with nitrogen or CO2 in gas grids with low calorific values), THT is added as an odorant and the biomethane is injected into the natural gas grid.
In the Bio-Up®, the CO2 scrubbing solvent is regenerated by using heat. The design of the Bio-Up® allows heat recovery and integration of the recovered heat in the digester. Well insulated small scale digesters do not require additional heat supply and can be fully heated by the recovered heat of the Bio-Up®. The heat use of the Bio-Up® is 0,65 kWh/m³ biogas (55% CH4), of which up to 75% can be recovered. The source of this heat can be raw biogas, biomethane or biomass. By using biomass (e.g. wood chips) to supply the heat, the biomethane production can be maximized.

The Bio-Up® system 

A Bio-Up system has all functions included in 1 installation:

  1. Heating
  2. Pressurization (to local grid pressure)
  3. Biogas Upgrading
    1. CO2 removal
    2. H2S removal
    3. Siloxanes removal
  4. Gas Drying
  5. Online quality control
    1. Analyzers
      1. raw biogas
      2. biomethane
    2. Gas chromatograph
  6. Quality steering
    1. CO2
    2. N2
  7. Odorization
  8. Grid injection
  9. Communication with grid operator

Bio-Up is available is biomethane capacities of 20 and 40 Nm³/hour.

Advantages of the Bio-Up® system

1. Fully automated and remote controlled
2. Service contract with experienced maintenance partner and 24/7 emergency assistance
3. High efficiency, all energy in the biogas is upgraded to biomethane with a profitable yield
4. Non-pressurized system
a. Uniquely low emissions to the environment
b. Safe and reliable
5. Ready-to-use: the system is containerized and is quick and flexible to set up
