Abstract

L'invention concerne un dispositif et un procédé pour le chauffage, le maintien à température et le réchauffage de pipelines isolées thermiquement (1) et utilisées pour le transport de fluides, en particulier de produits pétroliers visqueux, en vue de l'amélioration de l'aptitude au transport par réduction de la viscosité, et en vue d'éviter une solidification du pétrole en cas de chute au-dessous du point d'écoulement. Pour cela, le pipeline est équipé de stations de chauffage travaillant sur le principe du couplage force-chaleur. Alors que l'énergie électrique qui y est produite sert à alimenter des tronçons adjacents du système électrique de chauffage de pipelines en parallèle, dans la zone de chaque station de chauffage, la chaleur dégagée est transférée à un courant latéral du fluide transporté (dérivé au moyen d'une vanne d'arrêt 2) qu'on fait passer à travers la station de chauffage, et qui est ensuite renvoyé dans le courant de transport principal. Avec ce procédé à combinaison, il est possible d'obtenir des degrés d'efficacité totale du procédé de chauffage décrit qui atteignent plus de 80 %, rapportés à l'énergie thermique du combustible primaire, par exemple du gaz naturel, qui est utilisé.
