Which companies have implemented \"post-alkaline washing\" + \"smoke abatement\" measures on the flue gas from sulfur recovery units, and are there any specific standards or regulations serving as a basis for this? Is there no problem with actual production?
There is post-alkaline washing indeed, but what is whiteness removal smoke? Give a brief introduction
Eliminating white smoke mainly refers to the appearance of a white trail from the exhaust chimney.
Leader Hu, the post-alkaline washing process is now quite common in sulfur recovery units, mainly to ensure that emissions meet the required standards. However, in the case of sulfur recovery, the volume of flue gas is generally at least 1-2 orders of magnitude less than that in catalytic cracking and thermal power plants; as a result, white smoke emanating from chimneys is rare. Therefore, it is also uncommon to hear about measures taken to eliminate white smoke in sulfur recovery processes.
I had only heard of the term “little white dragon” before; I’ve never heard of eliminating white smoke.
So it’s good to explore more – knowing more can only be beneficial!
It seems I need to build more devices!
We do this followed by an alkaline wash or ammonia wash, as new standards require that old installations meet levels below 100.
Does eliminating white smoke mean removing the white trail that appears at the chimney?
Yes, there is blue smoke in some areas, which indicates an abundance of aerogel!
We use the ammonia-based desulfurization method along with smoke suppression
