Ion liquid desulfurization is used for sulfuric acid exhaust gas
Thread Content
For sulfuric acid exhaust gas, ion liquid desulfurization is used; whether it is one rotation with one absorption cycle or two rotations with two absorption cycles, this method enables ultra-low levels of sulfur dioxide emission, results in smoke-free operation, offers good performance, and is cost-effective； If two rotations and two suction cycles are used, the production cost of sulfuric acid can be reduced by 10 yuan per ton. 、
It can also be paired with a liquid SO2 unit
I’ve only heard of this process; I’ve never seen any descriptions of the equipment.
No drawings, no process flow diagrams – this only deserves a poor rating
Could you give a detailed introduction to the one on the 1st floor?
Acid production from smelting flue gas at 500 kt/a; hydrogen peroxide is used for treating sulfuric acid exhaust gases, while ionic liquids are employed for flue gas desulfurization.
If the flue gas still contains about 20,000 parts per million of sulfur dioxide after conversion, can the ionic liquid stabilize its absorption and reduce this level to below 100?
No problem, it’s just a design issue
