How should the desulfurization system for 4.3m coke ovens be upgraded under the new environmental emission standards
Thread Content
The 4.3m ramming coke oven was put into operation in 2004; it uses the HPF desulfurization process. It can meet the old standards, but meeting the new emission standards poses some challenges – what modifications and upgrades are needed in terms of the process?
There are two methods: one is to reduce the sulfur content in the coal fed into the furnace, and the other is to increase the circulation rate of the absorbent solution
Hello, owner. What are the current sulfur content in the inlet air and the hydrogen sulfide content at the outlet of your company’s desulfurization unit? Do you have any data on the parameters of related equipment? You can send it to me for analysis, or we can come to the site for an on-site inspection.

Desulfurizing coke oven exhaust gases is very simple; the ammonia method can be used for this purpose
Even with excellent gas desulfurization, the flue gas emissions may still exceed the limits; leaks in old coke ovens cannot be ignored. If it’s really not possible to meet the standards, then it’s better to install a flue gas desulfurization system
On the one hand, it is to enhance desulfurization; the PDS+tannin desulfurization process designed by our company results in reduced H2S levels after desulfurization
It’s best to combine dry and wet methods for the lowest cost
