This patent describes a method for converting sulfur dioxide and/or nitrogen oxides in a mixture thereof with at least one other gas to separable forms comprising: passing the mixture of gases through a streamer corona discharge zone defined by spaced electrodes; periodically dissipating in the zone pulses of electrical power of sufficiently high voltage to establish a continuous pulsed streamer corona discharge whereby the sulfur dioxide and/or nitrogen oxides are converted to acid mist and/or particle aerosols; the improvement comprising establishing a streamer corona discharge by applying fast-rising narrow pulses in a zone defined by electrodes spaced in a wire-cylinder or wire-plate geometry.
