The biogas process
![Page 4: Step by step powerpoint presentation](https://reader035.fdocuments.in/reader035/viewer/2022062503/58cfb3991a28ab223a8b53c5/html5/thumbnails/4.jpg)
Benefits of our pre-treatment Turbo Tank
Hydrolysis – 50C - acid environment
Methanogenesis – 40C neutral PH
Harvest biogas faster – in just 4 weeks
Feed 20% less feedstock
Greater biogas yields,15–30% more

1 - Feedstock is taken from the clamps and loaded into the feeder

2 - The feedstock is moved to the Vogelsang energy jet and RotaCut

3 - The liquid feedstock is moved to the Turbo Tank
2-3 days
Hydrolysis50-55

4. The liquid feedstock is then transferred to the main digester tank – Biogas production
15-20 days
Methanogenesis
41-44oC

5. Some of the biogas is used to generate electricity using a Combined Heat and Power (CHP) unit.
The AD plant will run on self-generating power
Each year the CHP will prodce - 4,000,000 kWh/a
electricity
4,700,000 kWh of thermal energy

6. Biogas is moved to the upgrader, where it is cleaned to generate Biomethane
The biomethane should contain at least 97% methane to be entered into the grid. Need to ensure consistency on 97/98%.

7. Biomethane is moved to the Grid Entry unit
This unit monitors the quality of the gas and ensures that it conforms to the specifications and pressure required within the grid.
To bring the biomethane up to the same energy content, the Grid Entry Unit adds propane (approximately 4%) must be added at the point of injection. An odorant must also be added for health and safety reasons.

8. Biomethane enters the National Gas Grid and reaches the end user
Once in the grid, it is easy to arrange to sell the gas to residential and industrial customers

9. Digestate is removed from the main digester tank, separated and returned to farm land
