Fat Splitting Plant

Hydrolysis, also known as splitting, uses water and steam to react with oil or fat at high temperatures (210-250°C) and pressures (30-60 bar), creating “sweet-water” (glycerine in surplus water) and crude split fatty acids. Different fats and oils are utilized to get the desired chain length. Splitting takes place in high-pressure columns with heat recovery. Fat/oil enters from the bottom, water from the top, and high-pressure steam propels the operation.

Fatty acids are flashed under vacuum to dry and avoid reversal, and then purified by distillation. Sweet water is flashed at atmospheric pressure, pre-concentrated with steam in a vacuum, treated to eliminate fatty debris, then concentrated in a multi-effect evaporator. The crude glycerine is subsequently purified by distillation, deodorization, and bleaching.

What is Fat Splitting Process?

Fat Splitting Process: Triglycerides are hydrolyzed and gradually transformed into diglycerides, monoglycerides, and glycerol throughout the splitting process. When glycerine and water are continuously removed, the balance is shifted, producing fatty acids:

– DG + FFA = TG + H2O

– H2O + DG = MG + FFA

– Glycerol + FFA + MG + H2O

A mixture of mono-, di-, and some triglycerides will be present in the result if the fat splitting process is not completed.

Feedstock Types: Hydrolysis is a procedure that separates oil, namely TG, DG, and MG. The most commonly used feedstocks in industrial practice include lard, palm oil, coconut oil, palm kernel oil, rice bran oil, acid oil, high FFA and non-edible grade tallow, and fatty acid distillate from refineries. Various fats and oils are used to provide the appropriate chain length profile for the desired items.

Key Steps in the Fat Splitting Process

Step 1

Pre-treatment

Removal of impurities and water from oils and fats.

Step 2

Hydrolysis (Fat Splitting)

Hydrolysis, also known as splitting, uses water and steam to react with oil or fat at high temperatures (210-260°C) and pressures (30-60 bar), creating "sweet-water" (glycerine in surplus water) and crude split fatty acids. Different fats and oils are utilized to get the desired chain length.

Step 3

Fatty Acid Drying

Crude fatty acids from the splitting column are flashed to remove residual moisture. These fatty acids, which are initially dark and impure, are then purified or fractionated through fractional distillation.

Step 4

Glycerine-Water Pre-Concentration

Crude glycerine is continuously extracted from the bottom of the splitting column and flashed to increase its concentration

Step 5

Pre-Treatment of Glycerine-Sweet Water

mulsified fats in the sweet water are converted into non-soluble soap and filtered out to purify the mixture.
