Metallurgical hot coke in wagon

The wet quenching for coke is considered as a Best Available Technology for coke oven plants (IPPC 2001). The apparatus for performing this process includes a quenching tower connected with a condensor separator and having a buffer space for the quenching vapors. The buffer space has a closable fresh air valve and the condensor separator has a condensor return with an intermediately connected water purifier and the condensor separator and buffer space are connected with each other. A twin cooling system can be connected with a by-pass for feed back which receives fluid from the water purifier.

There are also improvements on the wet quenching process, such as the quenching tower from several companies worldwide (such as TechnicaM). The wet coke quenching assumes spraying over burning coke of water in the special facility of the quenching tower. In other words, hot coke is delivered to the quenching tower where cooling water quenches and cools down the coke to the lower temperature. It is then discharged onto a wharf and then to the screening tower, where the process depends on the final product. A typical process control automation system enhances the pump work control, the auxiliary equipment work control and the quenching cycle control.
