<p>The method for cleaning a Claus plant having a Claus furnace and downstream plant parts e.g. separators, catalytic reactors, sulfur condensers and heat exchangers when the plant is moving, comprises keeping the downstream of the Claus furnace-lying plant parts at 150[deg] C during the cleaning, and forming an increased portion of hydrogen in the Claus furnace by the supply of a gas with an oxygen portion of up to 28 vol.%. The temperature of the downstream of the Claus furnace not exceeds 155[deg] C at the exit of the sulfur condensers during the cleaning. The method for cleaning a Claus plant having a Claus furnace and downstream plant parts such as separators, catalytic reactors, sulfur condensers and heat exchangers when moving the plant, comprises keeping the downstream of the Claus furnace-lying plant parts at 150[deg] C during the cleaning, and forming an increased portion of hydrogen in the Claus furnace by the supply of a gas with an oxygen portion of up to 28 vol.%. The temperature of the downstream of the Claus furnace not exceeds 155[deg] C at the exit of the sulfur condensers during the cleaning. The Claus furnace is operated with 50% of load during the cleaning. The pressure of the produced vapors in the sulfur condensers is increased, so that a temperature of 145[deg] C adjusts itself at a tube wall of the heat exchangers on the sulfur condenser side.</p> |
