Oleochemicals:Stearic-,Palmitic-,Myristic-,Lauric-Acid

Oleochemicals
Stearic acid, palmitic acid, myristic acid, lauric acid and glycerine are all derivate byproducts from cooking oil processes. After through further processes such as fractionation, hydrogenation, splitting, acids destillation, granulation, and concentration increasing from sweat water, we got those above products. After hydrogenation and splitting processes we got free fattig acids and sweat water. Free fattig acids would had undergo further processes: filtration and vacuum destillation process to seperate light fraction from heavy fraction. From light fraction we got hexanoic acid, octanoic acid and decanoic acid, and from heavy fraction we got lauric acid, myristic acid, palmitic acid, and stearic acid. Sweat water would go further distillation processes to increase glycerine concentration. All those derivated products are highly economic value added products for cosmetics-, resins-, pharmaceuticals-, soaps-,foods-industries and other daily products. We can also produced biodiesel as renewable energy for diesel engine machines to replace diesel oil from those byproducts.
Other products from those derivate such as soaps, margarine, Glycerinemonostearate, palm waxes, etc.

Olein/Cooking oil

Cooking oil processes from palm oil are :
1. Degumming to eliminiert gums and other impurities by using phosphoric acid
2. Bleaching to get colour we want by using bleaching earth and carbon active in proportion ammount.
3. Deodorising to eliminiert stinky odor by using superheated steam (dry steam)
4. Refinering to get refined bleached deodorize palm oil (RBDPO)
5. Fractination to seperate solid fraction from iquid fraction. Solid fraction wird go to further processess (crystallization process and splitting process)
6. Liquid fraction (refined bleached deodorize oil/RBDO) would refined to decreased free fattig acid as low as allowed for cooking oil and finally we got olein/cooking oil.
