Title (EN) AUTOMATED RE-MELT CONTROL SYSTEMS
(FR) SYSTÈMES DE COMMANDE DE REFONTE AUTOMATIQUE
Abstract:
(EN) A system may automatically control a pipeline heating system to maintain a desired temperature and/or to provide flow assurance of process fluid along a pipeline. The system may identify the occurrence and location of the solidification of a given process fluid or the melting of the given process fluid by monitoring temperatures along the pipeline and identifying from the monitored temperatures the occurrence and location of a latent heat signature associated with the solidification or melting of the given process fluid. The system may determine a distribution of solidified process fluid along the pipeline. The system may determine the percentage of a given section of pipeline that is filled with solid and/or liquid process fluid on a meter-by-meter basis. The system may perform automated re-melt operations to resolve plugs of solidified process fluid that may occur in the pipeline.
(FR) Un système peut commander automatiquement un système de chauffage de pipeline afin de maintenir une température souhaitée et/ou de garantir un flux de fluide de traitement le long d'un pipeline. Le système peut identifier l'apparition et l'emplacement de la solidification d'un fluide de traitement donné ou la fusion du fluide de traitement donné en surveillant les températures le long du pipeline et en identifiant à partir des températures surveillées l'apparition et l'emplacement d'une signature thermique latente associée à la solidification ou à la fusion du fluide de traitement donné. Le système peut déterminer une distribution de fluide de traitement solidifié le long du pipeline. Le système peut déterminer le pourcentage d'une section donnée de pipeline qui est remplie de fluide de traitement solide et/ou liquide sur une base de mètre par mètre. Le système peut effectuer des opérations de refonte automatisées pour éliminer des bouchons de fluide de traitement solidifié qui peuvent se produire dans le pipeline.
