The acidic gas from the pre-hydrodesulfurization tower cannot be discharged

The acidic gas line is blocked in winter; will acidic gas also cause blockages?
Rust scale with water, crystals, or corrosion
Add heating. It got clogged here before too; there was too much water flow:lol:lol
The key issue is the water problem; under normal conditions it shouldn’t get clogged, so an analysis of the water content is necessary
It’s possible, but it crystallizes, and it’s difficult to clear it with steam (it can still be cleared :) ), but treatment with water might be faster.
There is a possibility of ammonium salts forming; in the past, the gas lines recovered from our gas holders have frozen over in winter.
