Checklist for building a biogas plant
book Source: Biogas Plants in Animal Husbandry
1. Finishing the planning, i.e. site evaluation, determination of energy demand and biomass supply/biogas yield, plant sizing, selection of plant design, how and where to use the biogas, etc., ail in accordance with the above planning guide.
2. Stipulate the plant's location and elaborate a site plan, including all buildings, gas pipes, gas appliances and fields to be fertilized with digested slurry.
3. Draft a technical drawing showing all plant components, i.e. mixing pit, connection to stabling, inlet/outlet, digester, gasholder, gas pipes, slurry storage.
4. Preparation of material/personnel requirements list and procurement of materials needed for the chosen plant:
- bricks/stones/blocks for walls and foundation
- sand, gravel
- cement/lime
- inlet/outlet pipes
- metal parts (sheet metal, angle irons, etc.)
- gas pipes and fittings
- paint and sealants
- gas appliances
- tools
- mason and helper
- unskilled labor
- workshops for metal (gasholder) and pipe installation.
5. Material/personnel assignment planning, i.e. procedural planning and execution of:
- excavation
- foundation slab
- digester masonry
- gasholder
- rendering and sealing the masonry
- mixing pit
- slurry storage pit
- drying out the plant
- installing the gas pipe
- acceptance inspection.
6. Regular building supervision.
7. Commissioning
- functional inspection of the biogas plant and its components - starting the plant
8. Filling the plant.
9. Training the user.
