  1. Procédé d'épuration du gaz brut provenant de la gazéification de combustibles solides, notamment de déchets carbonés, par un agent de gazéification contenant de l'oxygène, avec production d'un gaz brut ayant des températures de 500 à 1200°C environ et contenant des oxydes de carbone, de l'hydrogène et du méthane ainsi que, comme impuretés, de la poussière, du NH₃ et des haloacides, caractérisé en ce qu'il consiste à refroidir le gaz brut à des températures de 150 à 400°C, à envoyer le gaz brut refroidi ayant une teneur en NH₃ d'au moins 0,1 % en volume dans une zone de séchage par pulvérisation et à le mettre en contact avec de l'eau recyclée qui y est pulvérisée, l'eau recyclée étant évaporée entièrement, à envoyer le gaz brut contenant de la vapeur provenant de la zone de séchage par pulvérisation et ayant des températures de 80 à 250°C dans un filtre, à séparer à l'état sec dans le filtre au moins 80 % en poids des matières solides contenues dans le gaz brut à l'entrée du filtre et au moins 50 % en poids de composés halogénés, à envoyer le gaz brut du filtre dans une zone de saturation dans laquelle on met le gaz brut en contact direct avec de l'eau pulvérisée, à saturer ainsi le gaz brut de vapeur d'eau et à le refroidir à des températures de 50 à 90°C, à évacuer de la zone de saturation de l'eau contenant du sel et des matières solides et ayant un pH de 7,5 à 9,5 et à la charger dans la zone de séchage par pulvérisation en tant qu'eau recyclée et à retraiter le gaz brut provenant de la zone de saturation pour en éliminer la poussière et les gouttes de liquide contenant du sel.
  2. Procédé suivant la revendication 1, caractérisé en ce qu'il consiste à effectuer le retraitement du gaz brut provenant de la zone de saturation dans un électrofiltre en voie humide, dans un laveur en voie humide, dans un séparateur de gouttelettes et/ou dans un condenseur et à envoyer l'eau qui s'y forme en tant qu'eau recyclée à la zone de séchage par pulvérisation.
  3. Procédé suivant la revendication 1 ou 2, caractérisé en ce qu'il consiste à refroidir le gaz retraité, à en éliminer de la vapeur d'eau par condensation et à envoyer au moins une partie du produit condensé à la zone de saturation.
