Method for closing down and starting up sulphur production plants

摘要

Method for closing down and starting up sulphur production plants, in which flue gases are introduced into the sulphur production plant. The flue gas from steam generators is set, by reacting residual oxygen with reducing gases on noble metal catalysts at temperatures above 150 DEG C, to an O2 content of less than 0.05% by volume, preferably less than 0.01% by volume, is adjusted, by direct cooling with water, to temperatures of 120-400 DEG C and water vapour contents of 18-50% by volume, and is supplied to the sulphur production plant.
