Abstract

La présente invention concerne un procédé permettant de commander un potentiel d'oxydoréduction en temps réel dans un système à eau chaude afin d'inhiber la corrosion dans le système à eau chaude. Le procédé consiste à définir une ou plusieurs zones protectrices opérationnelles dans le système à eau chaude. Une ou plusieurs des zones protectrices opérationnelles comprennent une sonde de potentiel d'oxydoréduction qui est apte à mesurer un potentiel d'oxydoréduction en temps réel dans le système à eau chaude à une température et à une pression de fonctionnement. La sonde transmet le potentiel en temps réel mesuré à l'organe de commande, qui évalue et interprète le potentiel transmis afin de déterminer s'il est conforme à un paramètre de potentiel d'oxydoréduction. Si le potentiel mesuré n'est pas conforme au paramètre de potentiel d'oxydoréduction, l'organe de commande est apte à introduire une ou plusieurs espèces chimiques actives dans le système à eau chaude ou à les éliminer de celui-ci, et est en outre apte à modifier au moins un paramètre du système.
