Abstract

La présente invention concerne un procédé pour minimiser les dépôts de carbonate sur les surfaces d'échange thermique d'échangeurs thermiques dans le circuit d'eau de trempe d'une installation de gazéification à flux entraîné. Selon ce procédé, l'eau de trempe en excès du système de trempe (1) est détendue et nettoyée (2), puis elle est amenée à la pression de fonctionnement de l'installation de gazéification (3), du dioxyde de carbone est ajouté à l'eau de trempe (4) dans une quantité permettant d'obtenir un rapport calco-carbonique au moins égal à l'équilibre calco-carbonique existant, l'eau de trempe est chauffée au maximum à une température à laquelle la teneur dissoute en dioxyde de carbone dans l'eau de processus préalablement chauffée est supérieure à la teneur en dioxyde de carbone avant l'augmentation de pression de l'eau de processus, puis l'eau de trempe préalablement chauffée est conduite au système de trempe afin de refroidir le gaz brut. La dissolution du dioxyde de carbone permet d'obtenir un excès d'acide carbonique dans l'eau de processus qui agit de façon à dissoudre le calcaire.
