| titleOfInvention | The neutralization process of waste sulphuric acid with dust generated in refining stainless steel and the method of manufacturing gypsum with precipitate made the nertralization process |
| abstract | The present invention relates to a method for neutralizing waste sulfuric acid and a method for producing gypsum, the purpose of which is to neutralize waste sulfuric acid using the secondary raw material dust of the stainless refining process, and to prepare the precipitate generated in the process of neutralization into gypsum To provide a way to.n n n The present invention having such an object,n n n Obtaining a calcium hydroxide suspension by hydrating the secondary raw material dust of the stainless refining process,n n n Injecting carbon dioxide gas into the calcium hydroxide suspension to obtain calcium carbonate by a carbonation reaction, making the calcium carbonate into a suspension, neutralizing the stoichiometrically reacted calcium carbonate suspension with waste sulfuric acid, and neutralizing. Treatment methodn n n The technical gist of the method for producing gypsum comprising the step of filtering and drying the precipitate in the neutralization treatment is considered. |
