DRY FRACTIONATION PLANT

CUSTOMISED TO INCREASE YOUR PROFITS

With an Oiltek Dry Fractionation Plant you can transform your feedstrock into two or more new oil products - each with its own unique properties and applications.

Whether you only need single fractionation or whether you take full advantage of the flexibility of multiple fractionation, by fractionating the products of earlier fractionation to create superoleins, special mid fractions and hardstocks, we will provide the total process solution.

With the one Oiltek Dry Fractionation Plant the choice is yours - we provide the total, customised system that lets you selectively and efficiently fractionate your feed into products with the utility you and your customers demand.

OILTEK DRY FRACTIONATION PROCESS

By cooling the feedstock under carefully controlled conditions in our crystallisers we create a slurry of high melting stearin crystals in low melting olein liquid. Our technical objective is to grow large, hard stearin crystals of high purity. These pure stearin crystals can later be separated most effectively from the free olein liquid. In this way your olein yield is maximised.

The slurry is passed through a filtration section to separate the stearin crystals from the olein. The stearin is melted and both oils are sent to storage.

Four precisely controlled steps lead to consistent quality of output :

• Automatic heating of the feed oil while filling the crystallisers melts any pre-existing crystals that would interfere with later process steps.

• Computer programmed cooling creates a saturated stearin solution and nucleates stearin crystals.

• Extended holding at the crystallisation temperature allows crystals to grow into the desired composition and form and creates a slurry that is efficiently separated.

• Filtration by membrane filter press separates the olein from the stearin and allows you to recover a higher olein yield, with the extra olein being of the same quality as the original yield.

Fractionation is a physical modification process - so there is no chemical change to the products. And of course in the dry fractionation process, there is no use of costly of hazardous chemical additives, no yield loss and no contamination of the oils. Because it produces no effluent, the dry fractionation process is also environmentally friendly.
