  • One-spot car coke quenching process
    Patent number: 4396461
    Abstract: A process for quenching hot coke in a one-spot coke quench car. The process utilizes a unique arrangement of pipes and spray nozzles to quench the hot coke in a substantially watertight coke quench car having a sloping bottom. A plurality of pipes are directed downwardly from a header mounted on the bench side of the quench car to provide solid streams of water onto the shallow coke bed portion at the top of the sloped bottom for a portion of the quench period. After an initial period a flow of water from a plurality of spray nozzles mounted on additional headers is directed onto the substantially horizontal deep coke bed portion for the remainder of the quenching period. The unvaporized quench liquid is retained in the watertight car until the completion of the quench cycle when it is rapidly drained away.
    Type: Grant
    Filed: August 3, 1981
    Date of Patent: August 2, 1983
