Regarding the discharge volume of wet flue gas desulfurization wastewater
Thread Content
For coking gas subjected to wet desulfurization using the HPF method, with a processing capacity of 50,000 NM3/h, what is the approximate amount of waste liquid generated per day? Or please tell us the amount of waste liquid discharged at the treatment scale of the desulfurization method used by your company. Thank you
Coke oven gas is subjected to wet desulfurization using the HPF method, with a processing capacity of 50,000 NM3/h. The amount of waste liquid generated per day (i.e., the discharge volume) is approximately 20–30 cubic meters. Environmental regulations prohibit the discharge of such waste liquids; therefore, in the coking industry, efforts are currently being made to extract the double salts present in these solutions. The double salt obtained through ammonia-based desulfurization is ammonium thiocyanate, while that obtained through alkali-based desulfurization is sodium thiocyanate； This technology is now quite mature, so this method can be considered.
