Purifiers & Separators

A purifier is a type of centrifugal separator that we can use to separate two liquids with different densities, i.e. water and fuel. A purifier can remove some solid impurities as well. We can modify a centrifuge to make it a purifier.

In that, we should use a second outlet pipe for water discharging process. Typically, untreated fuel oil contains a mixture of oil, solids and water. Hence, a centrifuge separates the fuel oil into three different layers. During this process, a small quantity of the oil remains in the bowl of the centrifuge to form a complete seal at the underside of the bowl. We call it a dam ring that separates the fuel and water.

Clarifier is a type of centrifugal separator that we can use to separate solid impurities from fuel. However, a clarifier can remove some quantity of water as well. To form a simple clarifier, we can add an inlet and an outlet connection, and we can increase the efficiency by increasing the number of discs that we include in the clarifier; it increases the surface area, thus, helps in better separation.
