In the cleaning of a humid gas flow containing gaseous impurities, the gas flow is dehumidified by cooling. The cooled gas flow is reheated and then gaseous through a device (7') for the absorption of gaseous impurities. A desorption-gas flow is heated so as to form a hot-gas flow, which is conducted through the adsorption device (7') in order to clean the latter. The contaminated hot-gas flow is conducted to a combustion device (10') in order to be burnt. Hot combustion gases are removed from the combustion device (10') in order to take part in at least one of the heating processes by being introduced into and mixed with the cooled gas flow and the desorption-gas flow.
Dans le procédé d'épuration d'un flux de gaz humide contenant des impuretés gazeuses, le flux de gaz est deshumidifié par refroidissement. Le flux de gaz refroidi est réchauffé et envoyé dans un dispositif (7') conçu pour l'adsorption des impuretés gazeuses. Le flux de gaz de désorption est chauffé de manière à former un flux de gaz chaud qui est nettoyé dans ledit dispositif d'adsorption (7') afin de l'épurer. Le flux de gaz chaud contaminé est envoyé dans un dispositif de combustion (10') pour y être brulé. Les gaz de combustion chauds sont extraits du dispositif de combustion (10') pour être utilisés dans au moins un des procédés de chauffage par introduction dans le flux de gaz refroidi et le flux de gaz de désorption et mélange à ces derniers.
