Coke oven flue gas after wet desulfurization is discharged into atmosphere,which appears white smog because droplet is formed under relatively low ambient temperature at the outlet of chimney.In this paper,an appropriate white smog vanish process is selected based on the features of wet desulfurization and coke oven operation.Linear programming graphic is also established through Excel computation so as to obtain the key parameters in the white smog vanish process.
