Note on removal of sulfur from stack gases by an electrical discharge.
J Air Pollution Control Assoc 1971 Mar; 21(3):143-144
Based on the theory that the ionization energy of so2 is less than the other major gas constituents, and that it therefore may enter preferentially into reactions to form lower vapor pressure products, tests were conducted in an electrostatic precipitator-type reactor. Pulsed direct current, and more so, pulsed high-frequency current were found to be more effective than the constant direct current normally used for dust precipitation. Two types of high frequency generators were tested, a damped wave spark gas oscillator with a carrier frequency of 10 megahertz, and a radar generator with a 2,800-megahertz carrier frequency pulsed at 900 hertz with a pulse width of one microsecond. Sulfur was removed both as elemental sulfur and as sulfuric acid, while h2o and co2 were found to be reaction promoters.
