PULSED WET DISCHARGE AS AN EFFECTIVE MEANS OF GAS PURIFICATION FROM H2S AND ORGANOSULFUR IMPURITIES

A new technique for purification of,aas flows from hydrogen sulfide im purities was experimentally studied. This technique is based on the in itiation of the processes of oxidation of hydrogen sulfide and removal . of the products formed from a gas stream by means of a pulsed atmosp heric-pressure streamer discharge with liquid water supplied to the di scharge zone (a ''wet'' discharge). It was possible to achieve almost a tenfold decrease in the energy consumption for purification (decompo sition of H2S) as compared to an ordinary streamer discharge. The tech nique developed allows the gas flows to be cleaned of not only H2S but a large variety of impurities such as nitrogen oxides, carbon disulfi de, mercaptans, phenols, toluene, etc.
