Regarding the emptying of concentrated sulfuric acid storage tanks
Thread Content
I have a few questions regarding the emptying of concentrated sulfuric acid storage tanks. From the perspective of manufacturing enterprises, namely chemical manufacturers, and considering it from the standpoint of acid handling, they certainly do not want to empty the tanks due to the safety risks involved. But from a scientific usage perspective, is it necessary to empty the tank? I would also like to ask professionals in this field: does concentrated sulfuric acid (98%) not produce acid sludge? No need to clean the tank? Because some people keep arguing like this! ! ! Thank you! ! !
1. Acidic sludge will be generated; the amount of such sludge produced varies depending on the mixing process used. We produce acid by burning liquid sulfur; there isn’t much acid sludge, and usually the tanks aren’t cleaned during major overhauls
