Acid consumption of Siemens 3K chlorine press
Thread Content
The company produces 200,000 tons of ion exchange membranes; for 3K chlorine compressors, the water content is required to be below 50 ppm. How many kilograms of sulfuric acid are needed per ton of alkali to meet this requirement?
It also depends on the concentration of dilute sulfuric acid you use; generally, a concentration of at least 75% is sufficient. If you want a better water removal effect, it’s necessary to maintain a concentration of 80% for the dilute sulfuric acid. The target required by our company is no more than 15 KG per ton of caustic soda.
The concentration of dilute acid is kept around 80, but the water content seems not to reach 50 ppm. What is the moisture content of your company’s products?
100-150ppm; to reduce it to below 50ppm, it’s not enough to just increase the acid concentration – other technical approaches are also necessary.
This is a systemic issue; it’s necessary to determine the water content in your process gas as it enters the tower. Only then can it be calculated. The general acid consumption is 10 kg/TCL2–15 kg/TCL2.
