Oil-water separation scheme for water-containing dirty oil in the production of coal-based needle coke

Request for help: Colleagues, in the production of coal-based needle coke, it is difficult to separate the contaminated oil and wastewater during the process of increasing steam supply in the delayed coking unit. Is there any effective method for oil-water separation? The density of this oil is 1.02–1.05; the sedimentation and separation effects are poor, and emulsification between oil and water is severe. Please advise. Thank you
There are two methods: heating and evaporation for materials with low water content, and leaving them to settle for those with high water content. This applies only to ordinary lubricants; it’s hard to say the same for others.
The separation cost is high, and even if it is recovered, it has little value; the outcome remains the same: burn it! So, it’s best to directly turn it into water-coal slurry and use it to power boilers
I wonder if the solid content of yours is high? If there isn’t much solid content, you can try a coalescer. Or, if the solid content is high, a fiber ball coalescer can be considered
Okay, thank you very much. Let’s give it a try.

What is the name of your company? We have several oil-water separators in use here, and they’re working very well
