Percolation Process
Activated Fuller’s Earth used in the
percolation filter process is in the granular form, this process
is usually used for light colour oils like base oil distillates,
mainly to improve it UV and PNC values.
PERCOLATION: The term ‘percolation’ is
given to that method of filtering in which the oil to be decolorized
is passed through a bed of granular adsorbent aided via the help
of gravity.
FILTRATION: Filtration is the general term
applied to the process of removing colour and suspended matter
from base stocks for specialty products.
The percolation method is a modern yet a very
simple process. At times you would be surprised that even simple
adsorption using this method can do wonders to improve the quality
of oil. It consists of a vertical steel cylinder closed at both
ends and provided with suitable man-heads and pipe connections
at the top and bottom to permit the introduction and discharge
of clay and oil. A perforated plate or a wire screen at a slight
distance above the bottom is provided over which a heavy canvas
blanket is placed and clamped to hold the clay in filter yet
allow oil to pass through and out of the filter. Size of these
filters varies considerably from capacities starting at 3 MT
to several hundred.
