Anaerobic Digestion Facility Ventilation
Anaerobic Digestion Facility Ventilation
(OP)
I'm working on the ventilation design of an anaerobic digestion building.
Here's the description:
- Building volume: about 400000 cu.ft.
- The building is attached to the digestion chambers, and the chambers can be accessed from inside the building.
- The digestion chambers contains methane gas, but is normally enclosed.
- Two 200hp diesel wheel loader are operated in the building to load the organic load in and out of the chambers
- The chambers are positively pressurized.
What's your opinion of these:
1. the NFPA classification & ventilation rate?
2. the ventilation rate for the two diesel wheel loader?
3. Positive or negative pressurization of building?
Thanks

RE: Anaerobic Digestion Facility Ventilation
If the loaders are moving the contents outdoors keeping any kind of pressurization in the building will be impossible while that operation is going on. I'm thinking the best bet would be lots of airflow through the building into the digester units and out the far end whenever they are open.
