Process for removing hydrogen and / or carbon monoxide from an air stream

摘要

In the inline purification of process air a coarse separation of dust/soot particles is carried out mechanically through a cloth, centrifuge or electrostatic collector. A fine separation is achieved in a wash process, particularly an overflow venturi washer. Particles and aerosols with a diameter less than 20 mu m are removed before the catalytic oxidation of hydrogen and carbon monoxide.
