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.
