When sulfur is used to produce acid and then absorbed by ammonia water, the circulating mother liquor in the tail absorption tower turns red – red, red? ? ? What’s the reason! I forgot to take a photo. It’s red. Please ask an expert for help! I haven’t found an answer myself. Have any experts encountered this phenomenon?
We also use ammonia for absorption; we have never encountered this situation
It should be the color brought by ammonia itself
Rust from the system got carried in
