Abstract
A process for removing pollutants including sulfur dioxide and/or nitrogen oxides from effluent gas which relies on the use of corona discharge to enhance the efficiency of the process. In one embodiment, corona discharge is utilized in a conventional spray dryer. In another it is combined with an ammonia injection technique. In yet another embodiment corona discharge treatment is followed by exposing the acidic mist byproduct leaving the discharge treatment chamber to a neutralizing reagent directed into the path of the effluent. The reagent may be provided with an electrical charge opposite to that on the acidic mist byproduct emerging from the corona reaction chamber to enhance neutralization.
