We can provide turnkey plant for you:

Fatty acid distillation and fractionation projects with capacity ranging from 50t/d to 400t/d
Glycerol concentration and refining projects with capacity ranging from 30t/d to 100t/d

1. Oil and Fat Splitting

Oil splitting (or hydrolysis) is performed under high pressure(55-60bar) and high temperature(240-260℃), resulting in the formation of crude split of fatty acids and crude glycerine dissolved in the excess water. The split degree using high-efficient and countercurrent splitter designed by Myande can reach 99%.

2. Glycerine-water Concentration
The sweet water is discharged from the bottom of the splitter continuously. Then the sweet water will be concentrated to 84%-88%(w/w) crude glycerine through the following process.
Glycerine-water concentration
3. Glycerine Refining
The crude glycerine is deaerated and further flashed to remove a part of water, then pumped into a packed tower to separate the light impurities and the heavier salts from the glycerine. The distilled glycerine via deodorization and activated carbon bleaching can obtain pharmaceutical grade glycerine with the purity above 99.5%.

4. Fatty Acids Distillation & Fractionation
Fatty acids distillation is applied to separate the light and heavy boiling impurities by several structured packing distillation columns (Usually two). The first column removes the light molecules, such as short carbon chain fatty acids and ketoaldehydes. The second column obtains the mixed, colourless product, normally C16-C18.
Fractionation is used to separate different length fatty acids by three or four series columns. For example, we can separate C12, C14, C16, C18 fatty acids from palm kernel oil hydrolysate by four-column in series.
