Technical Document

Brief Overview

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.


Manufacturing Process

Palm fruit from the fields undergoes threshing to remove the main stem and attached spikelets.

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.

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.

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.

Solvent extraction with methanol removes free fatty acids from palm oil, crucial for preventing oxidation and unwanted odors.

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.

To produce fully refined glycerine, leftover methanol from the deacidification process is evaporated from the glycerine.

Pharmaceutical Industry

Glycerine is a necessary ingredient in a number of medications, such as anesthetics, cough medications, and suppositories.

Cosmetic Industry

Glycerine helps cosmetics stay softer and creamier by retaining water, which increases the goods' shelf life.

Food Industry

Glycerine is utilized in many food products as a sweetener and to help athletes stay hydrated.

Industrial Uses

Glycerine is being researched as an additive for gasoline to lower harmful emissions. Its lubricating properties increase overheating prevention, reduce friction, and enhance mechanical efficiency. Because glycerine is economically viable, it finds employment in both industrial applications and chemical intermediates.
