Help: Tar dehydration
Thread Content
After tar dehydration, the water content remains high; the outlet pipeline of the tank needs to be modified, with centrifugal dehydration being planned as the method. What type of centrifuge would be suitable?
Fulwei’s three-phase super centrifuge
Three-phase horizontal screw centrifuge dehydration in Europe
I agree with what was said on the 2nd floor – the three-phase super centrifuges from Fulewei are quite good; our company uses them as well.
What if the tar residue has already been removed? There’s no residue left now; it’s just a matter of separating the oil from the water
The three-phase horizontal screw also removes water at the same time; is the tar content’s moisture level very high in the original post?
It’s said that three-phase models are more sophisticated, but the focus is mainly on the separation of two phases. There are also centrifuges for two phases, yet it’s better to use a three-phase model. Both Foster and Alfa Laval options work fine
Both German Falco and Swedish centrifuges are acceptable; currently, the centrifuges used by coal tar processing enterprises in China for the pre-treatment of raw coal tar through dehydration and deslagging are mainly produced by these two manufacturers. Our unit uses Alfa Laval’s P2-520, and it works quite well.
The key is what type of coal tar you have What was the moisture content after initial dehydration? What is your request? Not all devices are in ideal condition; the key is that they meet your process requirements.
