[Digestion] Removal of hydrogen Sulphide from biogas

[Les Gornall]

There is a mine of information on how to build small scale anaerobic digesters FREE on the website of GATE International a wonderful organisation that has been building small scale digesters in remote areas for several decades.  This will have all the information you need .

G'day Isiaka,

Hydrogen sulphide should be very low unless you are overloading the digester or are adding sulphur from protein(?). To make sure passing the gas through a steel wool pack works quite well (it can be regenerated if necessary). As far as corrosion of the motor you need to consider the cost of scrubbing (capital, operation and maintenance) compared to the slightly reduced engine life, accepting that the exhaust gases will be slightly acidic as well.

Happy digesting,
HOOROO
