Abstract
The process serves for removing carbon monoxide and/or hydrogen from an air stream by catalytic oxidation. Dusts and/or aerosols of a particle size of less than 20 μm are removed from the air stream upstream of the catalytic oxidation.
Claims17
In a process for removing carbon monoxide and/or hydrogen from an air stream in which the air stream is subjected to a catalytic oxidation, the improvement comprising removing dusts and/or aerosols of a particle size of less than 20 μm from the air stream upstream of the catalytic oxidation, and then subjecting the resultant catalytically oxidized gas to low temperature fractionation to produce high purity nitrogen.
An apparatus comprising a low temperature fractionation plant for producing nitrogen from air, and apparatus for removing carbon monoxide and/or hydrogen from an air stream comprising means for catalytic oxidation of carbon monoxide and/or hydrogen, means for removing dusts and/or aerosols of a particle size of less than 20 μm in upstream communication with the means for catalytic oxidation, and a conduit for passing resultant catalytically oxidized air to said low temperature fractionation plant.
