[Digestion] Digestion Digest, Vol 26, Issue 6

Mon Oct 15 20:40:56 CDT 2012

Dear All,
I'm a beginner in bio gas, I'm Indonesian country (south asia region),
in my country we are new for bio gas, so need more learn about this with
all aspects, I would like to know further about the:
1. As I read the CH4 (methane gas) make 23 times worse compare to CO2
due to  GHG, could I get the technical explaination about this? How the
process in the atmosphere for GHG effect by CH4 and CO2?
2. In bio gas installation what is the best parameters of bio gas for
gas engine?
3. What is the best technology for bio gas project for palm oil mill
effluent? Raw material of palm oil mill effluent COD: 55000 ppm, pH: 4
to 5, Oil and grease below 1%

Hoping some body would not mind to give me the explaination.

Best Regards++

Dear Mr. Tumwesige,

just chop up the material and feed it into the biogas plant. Everything
except the lignin would be turned into biogas. We regularly use green
leaves as feedstock. The midribs and veins accumulated in the biogas
plant
as undigested debris are removed by opening a drain valve at the bottom
of
the biogas plant.
Yours
A.D.Karve

Thank you very Dr. Karve.
Do you have an idea of how much gas is produced per 1kg of these
materials?

G'day All,

I have had a List message returned because it was too large for the 
recipient mail system (probably the attachments). Please be aware of 
this and avoid attachments (you may say that information is available 
and people can contact you directly). Also when Replying to a message 
delete the string of messages that sometimes accumulates. If you have 
this restriction you may need to check using the web interface at 
http://lists.bioenergylists.org/pipermail/digestion_lists.bioenergylists
.org/.

Happy digesting,
HOOROO

This material would have about 70 to 80% moisture and some lignin as
non-digestible material. It may give about 100 litres biogas per kg.
