What methods can be used to separate water from oil, and what is the underlying process for each method?

Question

Accepted Answer

Various methods like gravity separation, centrifugation, and filtration can effectively separate water from oil.

Gravity Separation: Utilizes the difference in density between oil and water; oil floats on top.
Centrifugation: Employs centrifugal force to separate water from oil based on density differences.
Filtration: Uses porous materials to allow water to pass while retaining oil; effective for emulsions.
Coalescing Filters: Designed to merge small water droplets into larger ones for easier separation.
Thermal Separation: Involves heating the mixture to evaporate water, leaving oil behind.
