Question

Following figure shows a typical biogas plant. Choose the correct option.

• A. A-Gas holder, B- Digester, C- Sludge
• B. A- Digester, B- Sludge, C- Gas holder
• C. A- Sludge, B - Gas holder, C- Digester
• D. A- Sludge, B- Digester, C- Gas holder

Answer 1

The correct option is A A-Gas holder, B- Digester, C- Sludge

The biogas production is carried out in anaerobic digesters known as Biogas plant. These have five components:

• An inlet to feed the slurry
• The fermentation chamber where the biogas is produced with the activity of microorganisms (Digester)
• The gas storage tank to store the gas produced (Gas holder)
• The outlet for the used slurry (sludge)
• The exit pipe for removing the gas produced.
