Abstract

The invention relates to a method for purifying a gas (G) which contains an impurity. In said method, the gas (G) is directed past a wall (32), whose temperature is lower than the gas, in such a way that the impurity condenses on said wall. In order to clean the condensed impurity easily from the wall in a method of this type, the gas which is to be purified is directed past a wall which is coated with a protective layer. The material of said protective layer has a melting temperature which is higher than the temperature of the wall.
