Comparison between advanced desulfurization technologies for coke oven gas and desulfurization technologies for exhaust gases from coke ovens

According to the emission standards for pollutants in coking chemistry, SO2 in the exhaust gases emitted from coke oven chimneys must be strictly controlled. At present, most coking enterprises choose desulfurization technologies for treating flue gas from coke ovens as their environmental protection measures; whether it is dry, wet, or semi-dry methods, these approaches require substantial investment and operating costs. Calculations show that burning 1 cubic meter of coke oven gas generates 6 to 8 cubic meters of waste gas; it is necessary to determine whether an advanced treatment process for deep desulfurization of coke oven gas should be used or a post-treatment desulfurization technique for coke oven waste gas We hope that experienced enterprises will participate in the discussions and provide information on the investment and operating costs for the advanced desulfurization and purification of coke oven gas, as well as the investment and operating costs for desulfurizing coke oven exhaust gases!
Thank you, please participate actively in the discussion!
Come and learn*, wait for the experts to answer, and earn some points while you’re at it:hug:
Is the investment for deep desulfurization of coke oven gas lower, or is the investment for desulfurization of coke oven flue gas lower?
I am capable of producing sodium thiocyanate with a purity of over 98%, anhydrous sodium thiosulfate, sodium sulfate, and sodium chloride.
The key lies in the subsequent industrial chain of coking; if the gas is used to produce methanol, synthetic ammonia, and natural gas, then the sulfur content in this gas can be kept at 20 milligrams after desulfurization. If it is burned in a regenerative furnace, the hydrogen sulfide level in the gas can be kept at 200 milligrams. Because even if you keep it at 20 milligrams, the SO2 level in the smoke still won’t meet the standards; this way, energy consumption is slightly reduced.
Only by clarifying the components can actions be taken accordingly
