Physical refining is an advanced oil purification process in which free fatty acids are removed through high-temperature steam distillation during the deodorization stage, eliminating chemical neutralization and maximizing oil recovery.

Best suited for high FFA oils such as palm oil, coconut oil, and rice bran oil
Requires highly efficient degumming and bleaching to remove phospholipids and trace metals
Supports zero-liquid-discharge (ZLD) and sustainability-focused refinery designs
Preferred globally under 2026 refining standards due to lower carbon footprint and operating cost
