Summary: | A method and a device intended to purify pollutants from an exhaust gas flow of an internal combustion engine operated with sulphur containing fuel, in particular of a ship internal combustion engine operated with heavy fuel oil, are provided. Exhaust gas flow is in contact with a solid adsorption agent of the adsorber in a first step and binding in particular acid pollutants, which comprise sulphur dioxide and sulphur trioxide. The exhaust gas flow is then guided by a second stage of the adsorber realising fine purification of the exhaust gas flow. The adsorption agent of the second stage is used in the first stage as an adsorption agent. |
