Abstract:

A process for controlling emissions resulting from hot coke being discharged from an oven of a battery of coke ovens from the beginning of discharge until the time when the coke arrives at a quenching station. The coke from the oven passes through a coke guide and a fume hood into an open-top, one-spot quenching car. The hood covers the car during discharge and is connected to an exhaust system, including a gas cleaning device, which draws air into the hood in an amount sufficient to control emissions and for combustion of the volatile matter and other combustibles emitted from the coke during the time coke is discharged into the quenching car and for a short period of time thereafter. During the movement of the open-top, one-spot quenching car from under the hood to the quenching station, the visible emissions given off by the hot coke are less than 40% opacity. The process can also be practiced with one-spot quenching cars of a different design, including a covered one-spot car that receives coke through an opening in the car.
