FlexiFrac Dry Fractionation
When oil is gently cooled, crystals will form spontaneously in the melt. After
sufficient maturation time, these crystals can be filtered from the remaining
liquid fraction, and this process thus results in 2 products: a solid fraction
enriched in high melting crystals, and a clear liquid fraction depleted from
high melting crystals. Typically this process is applied on oils that have an
appreciable content of high melting components. The prime example is palm oil:
this semisolid fat is not only the most produced oil in the world, it is also
the most fractionated oil in the world since it serves as natural source for
interesting solid fats as well as excellent liquid fractions. FlexiFrac
technology successfully combines the two aspects of the process, a controlled,
selective crystallization and high-pressure filtration of the crystal
suspension, into a smooth and flexible plant operation for a wide spectrum of
fats and oils. FlexiFrac features optimized cooling geometries in combination
with fully automated process temperature controls (see insert). This way, the
hold-up times can be minimized, and consistent high-quality output can be
guaranteed, for all kinds of feedstock
TX Cristallyzer
Being such a costeffective design, it is typically used for large palm oil
fractionation plants, where the long cooling cycle times guarantee steady
crystal growth and a smooth filtration.
Mobulizer TM
Our state of the art crystallizer, with an innovative cooling-integrated
agitation system, offers a true synergy of economics and performance. Its succes
lies in the combination of low shear mixing with superior heat exchange
properties. Therefore it can perform on those sensitive feedstocks where other
designs would simply fail. It is also the only crystallizer design that can be
used for FlexiFrac and iConFrac.
Tubular Crystallizers
Profiting from its high cooling surface to oil ratio, this crystallizer is often
selected for plants that require forceful cooling and robust mixing of viscous
oil slurries (e.g. fatty acid fractionation). The oil can be cooled rapidly and
homogeneously, which makes this crystallizer also very suitable for a wide range
of applications. The trademark short cycle times of these designs allow to
combine great flexibility with high capacity.
