Abstract
A method and apparatus for the wet quenching of coke is disclosed wherein hot coke is sprayed from above with quenching water, the steam generated by the heat of the coke is condensed by a spray of condensation water from the top of the quenching tower, and the hot condensate-water mixture is collected at the bottom of the quenching tower and recirculating to the top of the tower where it is sprayed between quenching operations to be cooled by a counterflowing stream of air. The cooled condensate-water mixture is suitable for reuse as the condensation spray water.
Claims6
In an apparatus for the wet quenching of coke including a quenching tower having an interior for receiving hot coke in a quenching car, first spray means above the hot coke for spraying the hot coke with quenching water in a hot coke quenching operation, second spray means in the upper portion of the tower for spraying the steam produced by spraying the hot coke with water for condensing the steam, and means at the bottom of the quenching tower for collecting the mixture of steam condensate and unevaporated quenching water, the improvement comprising third spray means located in the upper portion of the quenching tower and pump means for circulating the collected condensate-water mixture to said third spray means for spraying said condensate-water mixture in said quenching tower between periods of the hot coke quenching operation to cool said condensate-water mixture.
