Anhydrous sulfuric acid production
Thread Content
I would appreciate some guidance from those with more experience. The temperature of the gas after passing through the spray saturator and preheater is 75 degrees. The volume of gas entering the process unit is around 15,000. The total pressure in the saturator is about 2,000, and the acidity level is 3-4. The temperature of the mother liquor is around 47-48 degrees. Both the large mother liquor pump and the small mother liquor pump are operating normally; there is no crystallization occurring. How can production be increased? I’m seeking practical guidelines from those with more experience. The outdoor temperature is around -2 to -3 degrees
Non-crystallization is mainly caused by impurities; washing it out will solve the problem
Is the gas preheated to 75°C? So high?
Is the gas preheated to 75°C? So high?
The gas temperature entering the saturator is 65-70 degrees
What is the typical sulfur-ammonia yield in coking plants? Percentage of dry coal compared to coal loaded into the furnace
Consider appropriately reducing the acidity of the mother liquor; additionally, the temperature of the mother liquor can be lowered to around 45 degrees. As long as the ammonia level behind the device meets the specified standard, that is, ammonia in the gas can be removed, the process objectives are achieved.
