Abstract

Dans un procédé de régulation d'un appareil de séparation par distillation cryogénique, au moins une variable manipulée est modifiée, la variable manipulée ou chacune des variables manipulée étant modifiée au moyen d'au moins une variable contrôlée, chaque variable contrôlée étant ajustable au moyen d'une méthode de régulation et l'on utilise une méthode de régulation par méthode prédictive pour réguler au moins un point de consigne d'une des variables contrôlées.
