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

Answer:

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.
