I need a process flow diagram for sulfur-based acid production!
Thread Content
I have not been involved in the production of sulfuric acid from sulfur; previously, I was working on its production from pyrite. I am looking for a process flow diagram for producing sulfuric acid from sulfur, with a capacity of between 100,000 tons and 200,000 tons. Those with control points are better. I hope fellow sailors can help! ! This post was last edited by Sulfuric Acid Engineer on 2009-2-17 08:33.]
In fact, the process of producing acid from sulfur is shorter than that using pyrite; there are no purification steps, and the liquid sulfur filter can be considered the purification equipment for acid production from sulfur. Let me explain: Air enters the drying tower via a blower; from there it goes to the incinerator, then to the waste boiler, followed by the first conversion section, the high-temperature superheater, the second section, the heat exchange unit (tube side), the third section, the heat exchange unit (shell side), the economizer, the first absorption tower, the heat exchange unit (shell side), another heat exchange unit (shell side), the fourth layer, the economizer, the second absorption tower, and finally the exhaust chimney
What is your scale? Without specific parameters such as whether a waste heat boiler will be used, it is not possible to provide information. The process routes vary depending on configuration and scale.
After the four stages, the flow goes first to the low-temperature superheater, and then to the secondary absorber via the economizer.
