    摘要: 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. The method of the present invention has the following advantages: low cost for the equipment, good effect for treating coke-cooling wastewater, effectively preventing sulfur pollution and foul odor pollution, saving resources and improving the overall utility of the resources, and improving the cool coking efficiency.

    摘要: A process and an apparatus for separating and recovering waste alkali from a cyclohexane oxidation solution are provided. A gradient combination of the gravity separation technique, the vortex separation technique and the coalescence separation technique is used to carry out fine separation of the waste alkali liquor from the cyclohexane oxidation solution. The purified cyclohexane oxidation solution is fed into a down-stream apparatus. Most of the waste alkali liquor thus separated is recycled, while the remaining is expelled. The expelled waste alkali liquor is incinerated in an incinerator, followed by recovering the molten species using a pneumatic pulverization process.

    摘要: The present invention relates to a process and an apparatus for separating and recovering the waste alkali from a cyclohexane oxidation solution, and provides a process and an apparatus for separating and recovering the waste alkali from a cyclohexane oxidation solution. According to the invention, a gradient combination of the gravity separation technique, the vortex separation technique and the coalescence separation technique is used to carry out fine separation of the waste alkali liquor from the cyclohexane oxidation solution. The purified cyclohexane oxidation solution is fed into a down-stream apparatus. Most of the waste alkali liquor thus separated is recycled, while the remaining is expelled. The expelled waste alkali liquor is incinerated in an incinerator, followed by recovering the molten species using a pneumatic pulverization process. According to the invention, the content of Na+ in the cyclohexane oxidation solution fed into the alkane tower can be lowered to less than 3 mg/L, and the molten species resulting from incineration can be recovered 100%. Thus, risk of environmental pollution by the waste alkali liquor is substantially eliminated. While the invention is well suited to separate and recover the waste alkali liquor from a cyclohexane oxidation solution, it may be adapted to other chemical engineering systems for separating and recovering waste alkali liquor as well.
