Refined glycerine, glycerol, or glycerin, is a simple sugar alcohol with three hydroxyl groups that make it hygroscopic and water soluble. This material has a high boiling point and viscosity, which accentuate its natural sweetness and low toxicity. Its boiling point is 290°C, while its normal melting point is 17.8°C. The density of refined glycerine is 1.26 g/cm³. It appears as a translucent, odorless liquid. It is used in the culinary, pharmaceutical, cosmetic, personal care, and biodiesel manufacturing industries, among others. It is derived from petrochemical feedstock.
Threshing
Palm fruit from the fields undergoes threshing to remove the main stem and attached spikelets.
Sterilization
The palm fruit is sterilized with steam to prevent hydrolysis and oxidation. The applied heat expands internal moisture, aiding in the detachment of kernel, gum, and resin.
Digestion
Sterilized palm fruits are mechanically mixed and pounded in a rotating shift under high temperatures to release palm oil. Additional heat facilitates mixing due to the low viscosity of the oil.
Pressing
Processed palm fruit is pressed using a hydraulic machine to extract palm oil, applying pressure in a metal cage.
Oil Clarification
Extracted palm oil undergoes purification with hot water, removing impurities through filtration. The separated water and oil layers are decanted for further processing.
Deacidification
Solvent extraction with methanol removes free fatty acids from palm oil, crucial for preventing oxidation and unwanted odors.
Transeferication/Saponification
Hydrolysis breaks down deacidified palm oil into glycerol/glycerine and fatty acid chains. Further refining is necessary for the glycerine to be labeled as refined glycerine.
Glycerin Pre-treatment
The mixture of glycerine and fatty acid chains undergoes refinement through distillation. Heating the distillation column promotes glycerol and fatty acid evaporation, with glycerine evaporating more readily due to its lower boiling point.
Evaporation
To produce fully refined glycerine, leftover methanol from the deacidification process is evaporated from the glycerine.
