Bio Gas

Your website contains wonderful information that have really opened my mind. I'm currently a student from Nigeria undergoing a research on the development of a simple biogas purification system using iron fillings. would like to know if you have any desig


Will be highly grateful for any assistance render in this regards.

The method practised in Sri Lanka is to connect a 4 feet PVC line ( 2" diameter) to the distribution line ( assuming the distribution line is 1/2") , and fill the PVC tube with iorn pieces ( waste from lathe machines etc). the irion will react with H2S and for Reaction with iron oxide

Gas is pumped through a container of hydrated iron(III) oxide, which combines with hydrogen sulfide.

Fe2O3(s) + H2O(l) + 3 H2S(g) → Fe2S3(s) + 4 H2O(l)

In order to regenerate iron(III) oxide, the container must be taken out of service, flooded with water and aerated.

2 Fe2S3(s) + 3 O2(g) + 2 H2O(l) → 2 Fe2O3(s) + H2O(l) + 6 S(s)

On completion of the regeneration reaction the container is drained of water and can be returned to service.

Normally the iron can be used without replacement for about 6 months.
