How an oil purifier work

Bunker oil for combustion on ship's engines is of very low grade. They contain various impurities like particles and water droplets. Large particles in the fuel oil are allowed to settle down in the settling tank before they are pumped into the combustion process piping. After the particles have settled down, the fuel oil will be passed through some sort of filtration using coarse and fine filters. 

However, these processes are not sufficient to remove very fine particles and water droplets in the oil. 

If you have a bucket of a mixture of dirty oil and water and you leave it in a quiet place to settle, what will happen? You will find that after a long time, the oil will separate out from the water. And if the solid particles are heavy enough, they will also settle at the bottom of the bucket.

Notice that the separation is due to gravity (or specific gravity). Heavy bunker fuel oil has an SG of about 0.95, diesel oil about 0.85 and fresh water has an SG of 1. Because of the difference in Specific Gravity, or SG, the oil will float on top of the water. The solid particles that is heavier than water will sink down. But the above method will take a long time. Furthermore, if the SG's of the mixture are very close, the oil and the water may not be able to separate very well.

Our oil purifier series CYS uses the same principle for separating dirt or water from oil. Instead of using gravity, it uses centrifugal force.
