Purifier vs Clarifier
Purifier and clarifier are equipment used for cleaning or purification of fuel, mainly in case of ships and boats where it is common for fuel to get contaminated with water and other impurities. Though the basic purpose of both a purifier as well as a clarifier is same (cleaning of fuel) there are differences that will be talked about in this article.
The easiest of ways of cleaning of fuel is through the method of separation. Gravity is made use of in this method which separates fuel from impurities and water that are heavier than the fuel which floats at the top and is collected through an outlet that is made at the top of the container. The impurities and water can be finally removed by sludging of the tank at last.
Centrifuging is the process that is used for faster and most efficient cleaning of fuel. There are separators that work on the principle of centrifuging. However, they are divided on the basis of what they separate from the fuel. Separators that remove water from the fuel are called purifiers whereas those that remove solid impurities are called clarifiers. Centrifuging is a process that amplifies the effect of gravity and makes the process of purification faster and more efficient. The tank or the bowl in which fuel is kept is spun furiously producing a strong centrifugal force that throw away items with greater density at the periphery while fuel that has the lowest density remains at the center.
What is the difference between Purifier and Clarifier?
• When two liquids of different densities are separated using a centrifuge, the equipment is labeled as a purifier, but when the same centrifuge is used to separate solid impurities from the fuel, it is called a clarifier.
• Though a purifier also removes solids from the fuel to an extent, and a clarifier also removes water from the fuel, it is prudent to use both purifiers and clarifiers for complete purification of the fuel.
• A clarifier works as a back up system if one feels that purifier has not completely removed dissolved solid impurities from the fuel.
• Purifiers have a dam ring that works to create a line of separation between fuel and water. However, in clarifiers, instead of a dam ring, a sealing ring is used that prevents water and dissolved impurities to remain inside the fuel tank.
