Management issues related to wet-alkali desulfurization
Thread Content
For wet alkali desulfurization, the biggest problem is the absence of sulfur foam in the regeneration tank; this leads to a series of issues such as tower blockage and liquid carryover. So how can we ensure the flotation of the regenerated foam?
The operation of the regeneration tank without sulfur foam generation must be deviating from the design values
If it’s not a design flaw, then it needs to be determined by the test parameters during operation. There are many reasons why no excessive foam is produced
The content of by-products, the amount of suspended sulfur, the concentration of the alkaline solution, and the catalyst concentration, etc
