Treatment of spent sulfuric acid
Thread Content
What are the processes for treating waste sulfuric acid? And what are their respective application ranges? Thank you!
Our factory once developed a process for concentrating waste sulfuric acid. About 68% of the sulfuric acid is concentrated to around 95%. The method involves using a cast-iron pot for heating in order to evaporate the water and other impurities present in the acid; thereafter, a pump is used to create a vacuum, which draws away the steam, while sulfuric acid flows out from behind the pot.
This should be posted in the process discussion section of the engineering and technology exchange area; I’ll move it to the appropriate place for you.
We purchase large quantities of waste sulfuric acid on a regular basis; those who need to dispose of it should contact us at: 13852378886
I have been involved in the treatment of waste sulfuric acid–the preliminary design for producing sulfuric acid AN. I’m not aware of the source of the waste sulfuric acid you’re referring to, nor any other details about the manufacturing plant, so it’s difficult to say. Generally, it is used in the production of salts, and concentration requires consideration of impurities present
Monsanto’s acid waste recycling process in the United States: The process can be divided into the following four steps: 1. Burning of waste sulfuric acid to produce sulfur dioxide; 2. Cooling and purification of the sulfur dioxide gas; 3. Conversion of sulfur trioxide into another form; 4. Absorption of sulfur trioxide by water to form sulfuric acid
Upstairs, I can’t understand it. “00 Sulfur trioxide is converted into sulfur trioxide 00 – what does that mean?” It’s truly impossible to find even when searching hard; if you happen to bump into it, they’re everywhere! !

The treatment of waste sulfuric acid depends on its concentration as well as the other components it contains; this information is necessary to determine the appropriate material for the equipment. For low-concentration acid, it is better to use steel-lined graphite materials to concentrate it to about 70% acidity through steam, and then use tantalum heaters to further concentrate it to around 90% acidity
