    Coke Dry Quenching - e Plant Maintenance

    Following are the advantages of dry quenching: 1. It conserves water and does not release any contaminants to either air or fresh water. 2. 80% of the sensible heat is recovered in a waste heat boiler and steam is generated. power is generated in a back pressure turbine from this steam as a by product. The energy cost is almost negligible.

    dry coke quenching, air pollution and energy: a status report

    Dry quenching uses inert gases as a medium to collect heat from incandescent coke and to transport that heat to waste-heat boilers. Heat transfer from the coke to the inert gases is achieved by direct contact of the gases with the coke.3 Inert gases used to cool the coke and to transfer the heat are formed from an initial intake of air. Oxygen contained
