The waste sulfuric acid in the chlorine drying section is around 75%, while that from the Naipu pump is around 95%； The waste sulfuric acid from the Naismith pumps used for vacuuming in liquid chlorine systems is around 93–94% (depending on winter or summer)
How are these waste acids typically disposed of?
Dilute sulfuric acid dissolves chlorine; at 80% H2SO4 and 40°C, the solubility of chlorine in dilute sulfuric acid is 0.725%
After dechlorination, the spent sulfuric acid can be reused in equipment to produce 98% acid
78%; treated dilute sulfuric acid can be converted into 98% acid, seemingly by steaming in lead pots and decolorization with nitric acid
If you have waste acid, you can sell it to me at a price of over 60. It’s best if the location is close by; my factory is in Xuzhou, Jiangsu. My QQ number is 270259195. My factory has a capacity to store 200 tons of waste acid, and I need 15 tons of it per day
