Sulfur recovery and flue gas treatment in refineries, issues related to catalytic flue gas desulfurization and denitrification
Thread Content
As environmental protection requirements become increasingly stringent, refinery exhaust gases must be discharged in compliance with standards. I wonder if the sulfur treatment units in the refineries where you work utilize the process technology of two-stage Claus process + flue gas combustion followed by ammonia-based desulfurization? How effective is it? Is the ammonia-based desulfurization technique used in catalytic flue gas desulfurization? Could everyone please share their thoughts on the effectiveness? Thank you!
I’ve used it, and it seems to be good, since it’s in Hebei!
