[Digestion] Removal of hydrogen Sulphide from biogas

[Paul Harris]

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
