How to handle 15% dilute sulfuric acid
Thread Content
In the wet acid production process, apart from being sent back to the furnace for cracking, are there any other ways to handle 15% dilute sulfuric acid? Or are there any good ways to concentrate it? At a rate of 1 ton per hour, could pyrolysis in a furnace result in the acid concentration of the final product not reaching 98%?
Is it a dilute acid used for the post-washing step with hydrogen peroxide? Why is its concentration only 15%?
If it is clean, it can be used as supplementary water for the dry absorption section.
An activated carbon adsorption method, with the requirement that it should not be greater than 15
It can be added to circulating water to adjust the pH value and reduce hardness.
1. Find ways to reduce the production of dilute acid. 2. Find other uses, such as for regenerating the cation exchange resin in desalination systems. 3. Those with no other place to go are sent for wastewater treatment.
After purification, add it to concentrated acid: 13583319161
