  • Treating method and equipment for coke-cooling wastewater
    Patent number: 7419608
    Abstract: The present invention falls within the field of purifying oil-laden wastewater, which provides a method for purifying coke-cooling wastewater in a delayed coking process in petroleum chemical field. The method comprises the following steps: (a) cooling the coke-cooling wastewater produced in a delayed coking process to 5-55° C. under 0.1-0.25 MPa absolute pressure, to obtain cooled coke-cooling wastewater; (b) subjecting the cooled coke-cooling wastewater to solid-liquid separation, to obtain a coke breeze phase and a liquid phase; (c) further separating the obtained liquid phase, to obtain an oil phase and a water phase; and (d) further discharging water from the obtained oil phase, to obtain the separated oil phase. The present invention also provides an equipment for carrying out the method.
