Dehydration of oils

Oil water removal service by vacuum and centrifugation methods.


oil dehydration

dehydration of oil by vacuum and centrifugation

Water in oil has a destructive effect on its lubricating parameters, causes corrosion of the interior of the oil system and provides an excellent environment for the growth of microorganisms, which is why it is so important to eliminate water from the oil system, both lubricating and hydraulic.

Modern machines, equipped with small capacity oil systems, have a very small margin of safe water in the oil.

As little as a few percent of water content in oil can lead to the destruction of mated / lubricated components.

removal of water from oil by centrifugation

Removing water from oil by centrifugation uses centrifugal force to separate oil, water and contaminants. A typical centrifuge module is built with a centrifuge centrifuge, dosing pump and sludge pump, connected to a control system. The contaminated oil is pumped into a centrifuge drum rotating at high speed.

Under the influence of centrifugal force, solid particles are pushed toward the walls of the drum and directed into the sludge tank, while liquid contaminants such as water are separated from the oil by density differences. The resulting light and heavy phases are separately discharged from the system.

removal of water from oil by vacuum dehydration

When removal of free water from oil is insufficient, it is necessary to turn to vacuum dehydration methods of oil system care.
Unlike other water removal methods, vacuum dehydration allows both separated water and oil-bound water to be expelled from an oil system.

Vacuum dehydration removes 100% of free and emulsified water and up to 90% of dissolved water. In addition, it also removes 100% of adsorbed gases and up to 80% of dissolved gases in the oil.


removing water from oil – frequently asked questions

  • Water can get into the oil in various ways, such as condensation of water vapor, leaks in the system, flooding, contact with moist air or contamination during industrial processes.

  • Removing water from oil is crucial in the industry for several reasons. Water can cause corrosion, deteriorate product quality, reduce the performance of machinery and equipment, and lead to the formation of deposits and contaminants.

  • Leaving water in the oil can lead to a number of problems, such as:

    • – Corrosion of machinery and equipment.
    • – Reduction in lubrication efficiency.
    • – Deterioration of product quality, especially in the food industry.
    • – The formation of sediment that can disrupt the flow and operation of systems.

  • The cost of the oil-water removal process can vary depending on the scale and complexity of the system. However, the consequences of leaving water in the oil can be more costly, as a result of damage to machinery, reduced productivity and the need for more frequent repairs.
