How to address the issue of excessive hydrogen sulfide levels caused by liquid accumulation? What are the solutions for dealing with liquid accumulation in the regeneration tower?
The best solution is to eliminate the liquid retention phenomenon. First, analyze the causes of this retention: 1. The solution is too dirty； 2. The moisture content of NHD is above the standard ； 3. It is caused by an excessive circulation volume ； 4. It is caused by an excessively high temperature at the bottom of the tower. 5. The internal components of the tower are damaged. Solutions: Install filtering equipment, control the water content, appropriately reduce the temperature at the bottom of the tower, properly regulate the amount of solution circulation, and if necessary, shut down the system to inspect the internal components of the tower.
