Abstract

Se publica un método para el control del potencial de oxidación-reducción en tiempo real en un sistema de agua caliente pata inhibir la corrosión en el sistema de agua caliente. El método incluye la definición de una o más zonas protectoras operativas en el sistema de agua caliente. Una o más de las zonas protectoras operativas incluyen una sonda de potencial de oxidación-reducción es decir que se opera para medir un potencial de oxidación-reducción en tiempo real en el sistema de agua caliente a temperatura y presión de operación. La sonda transmite el potencial medido en tiempo real al controlador, el cual evalúa e interpreta el potencial que se transmitió para determinar si está de acuerdo con un marco del potencial de oxidación-reducción. Si el potencial que se midió no está de acuerdo con el marco del potencial de oxidación-reducción, se opera el controlador para alimentar una o más especies químicas activas dentro del sistema de agua caliente.A method for controlling oxidation-reduction potential in real time in a hot water system is published to inhibit corrosion in the hot water system. The method includes the definition of one or more operational protective zones in the hot water system. One or more of the operational protective zones include an oxidation-reduction potential probe, that is, it is operated to measure a real-time oxidation-reduction potential in the hot water system at operating temperature and pressure. The probe transmits the potential measured in real time to the controller, which evaluates and interprets the potential that was transmitted to determine if it agrees with a framework of oxidation-reduction potential. If the potential that was measured does not agree with the oxidation-reduction potential framework, the controller is operated to feed one or more active chemical species into the hot water system.
