Question

How can we remove oxygen from bio gas plant as this process take place in absence of oxygen.

Answer 1

Dear user,
Since air is also involved in biogas plant generation therefore it contains little amount of
oxygen as well.Oxygen can be removed in some cleaning processes done for CO₂ by the method
of membrane separation and pressure swing adsorption(PSA) that is the technique used to
separate substances on the basis of their molecular size and physical forces.
