PROCESS FOR PURIFYING METALLURGICAL GASES CONTAINING SULPHURIC ANHYDRIDE BY EXTRACTING MERCURY |
摘要 |
<p>The present invention relates to a process for purifying metallurgical gases containing sulphuric anhydride by extracting mercury, using the sulphurous anhydride which accompanies the metallurgical gases as an oxidizing agent for the mercury, an additional contribution of sulphurous anhydride being made when the latter is deficient, and employing in addition an acid to facilitate the oxidization of the mercury and a soluble thiocyanate in order to complete the oxidation of the mercury.</p> |
