    a) gazéification de charbon dans un étage de production de gaz (A), par amenée de chaleur et de vapeur de processus, pour la production de gaz brut;
    b) refroidissement du gaz brut produit jusqu'en-dessous du point de condensation de la vapeur d'eau qu'il renferme, pour produire un condensat aqueux;
    c) séparation du condensat aqueux du gaz brut produit;
    d) vaporisation du condensat séparé dans un étage de vaporisation (F) pour produire de la vapeur;
    e) recyclage de la vapeur de l'étage de vaporisation (F) dans l'étage de production de gaz (A), en tant que vapeur de processus,
       caractérisé
       en ce que l'on produit lors du refroidissement (étape b) du gaz brut par échange de chaleur, de la vapeur haute-pression et/ou basse-pression,
