amount of remaining free fatty acids in the oil is reduced to an absolute
minimum.

Cooling: The deodorized oil flow to the last compartment consisting of

exchanger where the heat of hot oil is transferred to dearated oil entering final
oil heater. The oil from final compartment is discharged by the Product Pump

and further cooled to storage temperature in De-aerating Economizer, Bleaching

Economizer, and Economizer in pretreatment section & Product Cooler. During
shutdown the cooling of the oil is carried out by recirculation of the oil from

product cooler E404 by product pump P 404 to Deaerator. The anti-oxidant is

mixed with oil in the Deodorizer. The finished oil is finally sent to storage via
one of the alternating Product Filters & Final oil cooler.

Distillate Recovery: Fatty acids and other materials, evaporated from the oil,
are condensed by contact with recycled and cooled distillate in the Vapor

Scrubber. The distillate is circulated by the Distillate Pump via the Distillate
Cooler where it is cooled by cooling water. Accumulated distillate is discharged

from the Scrubber to storage.

Trans and Tocopherol: The high efficiency (low amount of stripping steam)
and short retention time of the stripping column, combined with the possibility

to reduce the heat bleaching time or temperature, ensure optimum conditions

for controlling the process. The oil can thereby be properly deodorized without
the creation of trans fatty acids while also controlling the amount of tocopherol

removed from the oil.

Protection against Air Contamination: For optimum quality, especially when

processing unsaturated oils, the oil should be protected from air contamination
during the entire deodorizing process. The packed column type Deareator

ensures maximum removal of dissolved air before high temperature heating.

This also helps minimize polymerization of the oil on the inside of the heat
exchange coils of the heat Economizer.
