How does the Alcap system of oil purification work?

The Alcap system of oil purification is used in maritime and industrial applications to clean oil by separating water and sludge from the oil. This system uses a centrifuge that detects the density difference between oil and water, adjusting automatically to ensure proper separation. It continuously purifies the oil by spinning at high speed, forcing water and contaminants to the periphery, which are then drained, while clean oil is recirculated back.
