Maximum production of fuming sulfuric acid.
Thread Content
For the production of sulfuric acid from 200,000 tons of sulfur, how is the maximum yield of 20% free nicotinic acid calculated? Temperature conditions in the East China region.
Just look up a book on sulfuric acid and you’ll know. If one has a solid theoretical foundation, they can calculate the dry adsorption equilibrium by themselves.
Based on experience, the maximum output for short-duration shifts is around 140; it also depends on the size of the 105 heat exchanger – overheating can occur easily. In summer, the desired temperature cannot be maintained, and the acid concentration at 98% cannot be sustained
In the East China region, the maximum yield of standard fuming sulfuric acid (20%) from two-stage conversion and two-stage absorption sulfuric acid production plants can be 100% throughout the year.
