The distillers are towers with structured packing to fractionate heavy and light
boiling impurities and to ensure that the methylesters are distilled at the
lowest possible temperature。
Squeezing of the residue is carried out in a separate distiller。
Condensation can be carried out inside the tower over packing with cooling of an
external pump around or outside the tower in shell and tubes condensers。
In both cases heat is recovered generating low pressure steam。
Canned pumps with falling film reboilers or centrifugal pumps with suppressed
vaporisation reboilers are proposed according to the case。
Methylester fractional distillation
The single or multi towers plants are based on towers with structured packing.
Typical design of the towers foresees three products outlets ( top, sidedraw and
Of course all features of the distillation apply to the fractionation.
Controlled cooling/crystallising followed by pressure membrane filtration is
used for the production of oleic Fame。
Dry fractionation process leading to clean and simple operation guaranteeing a
lower operating and investment cost.
