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 is somewhat challenging – what modifications and upgrades are needed in terms of the process?
Shandong Rongxin seems to have three desulfurization towers; hydrogen sulfide levels behind these towers cannot be detected, and the flue gas from the coke ovens does not exceed the specified limits
Our company’s HPF uses a turbulent ball tower together with two desulfurization towers in series, and this setup can only keep hydrogen sulfide levels at 20 mg
