Abstract
Provided is a process for purfying a gas. In the process, the gas to be purified flows through a hollow dielectric tube. An electric field in the gas to be purified is created by a traveling electromagnetic wave which travels in the dielectric tube and is suitable for creating, in the gas, an atmospheric-pressure plasma which is not in local thermodynamic equilibrium, for the purpose of dissociating impurities in the gas in order 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.
