| titleOfInvention | Desulfurizing method of waste gas |
| abstract | PURPOSE: To prevent the formation of scales by calcium sulfate by increasing the concn. of magnesium sulfate in a liquid absorbent of magnesium hydroxide. n CONSTITUTION: The desulfurizing method of waste gas consists of an absorption stage (a) for treating waste gas contg. sulfur oxides with a slurry of magnesium hydroxide as an absorbent in an absorption tower, an oxidation stage (b) for oxidizing said liquid absorbent to form magnesium sulfate, and a double decomposition stage (c) for allowing a slurry of calcium hydroxide to react with said aq. soln. of magnesium hydroxide to separate and recover gypsum dehydrate and circulating a slurry of by-product magnesium hydroxide to the stage (a). In said method, the double decomposition rate in the stage (c) is controlled to a low value, and the magnesium sulfate concn. in the slurry of by-product magnesium hydroxide is regulated to 0.5W2.5g/ml. Consequently, the formation of scales by calcium sulfate can be prevented. n COPYRIGHT: (C)1986,JPO&Japio |
