Title: Apparatus for the plasma destruction of hazardous gases

Abstract

A plasma cell for destroying hazardous gases. An electric-discharge cell having an electrically conducting electrode onto which an alternating high-voltage waveform is impressed and a dielectric barrier adjacent thereto, together forming a high-voltage electrode, generates self-terminating discharges throughout a volume formed between this electrode and a grounded conducting liquid electrode. The gas to be transformed is passed through this volume. The liquid may be flowed, generating thereby a renewable surface. Moreover, since hydrochloric and hydrofluoric acids may be formed from destruction of various chlorofluorocarbons in the presence of water, a conducting liquid may be selected which will neutralize these corrosive compounds. The gases exiting the discharge region may be further scrubbed if additional purification is required.
