Abstract

Métodos para controlar la oxidación de iones bromuro en operaciones de desulfurización del gas de escape húmedo. Los métodos comprenden depurar un gas de escape que contiene iones bromuro en una operación de desulfurización del gas de escape húmedo, en la que la operación de desulfurización del gas de escape húmedo comprende contactar el gas de escape con un medio de depuración. El potencial de oxidación-reducción del medio de depuración se mide después con una sonda de potencial de oxidación-reducción. En respuesta al potencial de oxidación-reducción medido, un agente reductor se introduce en la operación de desulfurización del gas de escape húmedo para reducir y/o mantener el potencial de oxidación-reducción del medio de depuración por debajo del valor para la oxidación de los iones bromuro.Methods to control the oxidation of bromide ions in desulfurization operations of the wet exhaust gas. The methods comprise purifying an exhaust gas containing bromide ions in a wet exhaust gas desulphurization operation, in which the wet exhaust gas desulfurization operation comprises contacting the exhaust gas with a means of purification. The oxidation-reduction potential of the purification medium is then measured with an oxidation-reduction potential probe. In response to the measured oxidation-reduction potential, a reducing agent is introduced into the desulfurization operation of the wet exhaust gas to reduce and / or maintain the oxidation-reduction potential of the purification medium below the value for the oxidation of the bromide ions.
