Abstract

Provided are a process and apparatus for purifying a gas. In accordance with the process, the gas to be purified flows through a hollow dielectric tube. An electric field is created in the gas to be purified by a traveling electromagnetic wave which travels in the dielectric tube and creates, in the gas, an atmospheric-pressure plasma which is not in local thermodynamic equilibrium, for the purpose of dissociating impurities in the gas to form reactive compounds. The formed reactive compounds are reacted with a corresponding reactive material for eliminating the reactive compounds from the gas to be purified.
