Wastewater treatment for coking vent towers
Thread Content
What are some effective treatment methods for oily wastewater from coking vent towers? Please share your opinions, teachers
After sedimentation and separation in the oil-contaminated wastewater tank, the wastewater is fed into the wastewater stripping unit
For simple treatment, at present, the vast majority of wastewater from refineries is sent to wastewater stripping units. The wastewater from the top of the air defense tower is also recovered and reused in the cold coke water tank, where it is used as makeup water for that tank.
It can be transferred to the sludge oil tank, and when the coking tower is being preheated, it can be injected into the top of the tower as quench oil (make sure to remove water)
