Abstract
(EN) A wet flue gas desulfurisation device comprises an absorption column, a circulating pump and an absorbing agent slurry supply unit. In this control method for said device, a learning model is constructed, by machine learning, for the relationship between: explanatory variables which include the absorbing agent concentration in an absorption liquid, the circulation flow rate of the absorption liquid and at least one parameter that correlates with the output of a generator; and a target variable which is a future concentration of sulfur dioxide at the outlet of the absorption column. For each generator output, a predicted value of the concentration of sulfur dioxide from the learning model is calculated, and a table indicating an introduced amount of the absorbing agent and a circulation flow rate of the absorption liquid that would be required for the predicted value to be less than or equal to a reference value is created. On the basis of said table, control target values are determined for the introduced amount of the absorbing agent and the circulation flow rate of the absorption liquid, which correspond to the state of the generator.
(FR) Un dispositif de désulfuration de gaz de fumée humide comprend une colonne d'absorption, une pompe de circulation et une unité d'alimentation en suspension d'agent absorbant. Dans ce procédé de commande pour ledit dispositif, un modèle d'apprentissage est construit, par apprentissage automatique, pour la relation entre : des variables explicatives qui comprennent la concentration en agent absorbant dans un liquide d'absorption, le débit de circulation du liquide d'absorption et au moins un paramètre qui est en corrélation avec la sortie d'un générateur; et une variable cible qui est une future concentration en dioxyde de soufre à la sortie de la colonne d'absorption. Pour chaque sortie de générateur, une valeur prédite de la concentration en dioxyde de soufre à partir du modèle d'apprentissage est calculée, et une table est créée indiquant une quantité introduite de l'agent absorbant et un débit de circulation du liquide d'absorption qui seraient nécessaires pour que la valeur prédite soit inférieure ou égale à une valeur de référence. Sur la base de ladite table, des valeurs cibles de commande sont déterminées pour la quantité introduite de l'agent absorbant et le débit de circulation du liquide d'absorption, qui correspondent à l'état du générateur.
