Glycerine Distillation
The C.M. BERNARDINI glycerine distillation process is based on a very compact design composed of a single tower distiller, which incorporates the washing, rectification, main condensation and final condensation stages, with the vacuum system installed directly on top of the tower. High flexibility and possibility of coping with different grade raw materials are achieved by means of comprehensive automatic control system of all process variables.
High quality glycerine is obtained thanks to the washing stage which, due to the scrubbing effect, allows to produce very high quality glycerine even with lower grade raw materials.
Glycerine concentration of up to 99.8% is guaranteed by
means of the rectification stage.
The operating temperature is kept to a minimum thanks to
the very low pressure drop, and consequently operating
pressure, achieved by means of structured packing and
specially designed draw-off plates.
A fully continuous in-line bleaching unit is contemplated.
A wiped film evaporator is provided for as a secondary
distiller on glycerine from spent lyes or from
transesterification .
Miscellanea
In addition to the units detailed previously , C.M. BERNARDINI offers the following plants:
Fat Oil purification:
By acid treatment or by bleaching according to the product.
Hydrogenation:
Loop reactor for both total and selective hydrogenation of neutral oil and fatty acids. Total heat recovery
generating low pressure steam and pre-heating the next batch.
Sweet water purification:
Single or double step, semi-continuous or continuous.
Sweet water evaporation:
One to four effects according to the capacity.
Spent lyes evaporation:
Up to three effects with centrifuge or salt box for maximum glycerine recovery. Manufactured according to
client's requirements, in CS, or SS 2205 or copper nickel.
