[Digestion] Digestion Digest, Vol 7, Issue 3

[Vishwas Gokhale]

Dear Donna,
If you want to experiment with high pressure digestion system may be you can
work with number of digesters working in parallel. It seems nobody has
studied  anaerobic digestion at higher pressures. It would however be
necessary to install a safety vent system for pressures beyond acceptable
levels .

	We may get much better results. Maybe we may get crude oil  out of
this digesters. That is how the natural gas is produced in the first place.

>Dear Saroka,
you can use the floating dome of biogas plant, as a storage for the gas. In
this mode, the digester is filled with water. Introduce the gas into the
dome through the gas cock fitted at the top of the dome, which gets lifted
out of the water as it gets filled with gas. Close the cock when the dome is
full of gas and connect the gas cock to the gas burner. The weight of the
floating dome is generally enough to drive the gas to the burner. If the
weight of the floating dome is not enough to produce the necessary pressure,
you can place additional weights of the dome to create extra pressure. You
may have to remove the extra weights when filling your gas holder. Such a
biogas storage system can be fabricated from two plastic tanks or barrels,
having varying diameters, so that one barrel telescopes into the other one.

  ***********
  It seems this idea would work best with a Batch-type process rather than a
continuous feed, am I correct?  I bet I could set up several smaller tanks
in this manner and connect them to a manifold system whereby I could change
the tank supplying the fuel through the manifold as one tank empties and
another is producing.  
   
  What would be the safest / most effective psi for the pressure in the
lines? Would a regulator from scuba gear or maybe one for a propane tank
that hooks up to a gas grill be appropriate for measring the available psi?
   
  Thanks!
