Adds value to
reclaimed oils by
improving color
and reducing or
removing odors and
sulphur.
The CPS-series of
clay polishing
systems from
Redragon provides
an economical
alternative to
hydrogen treatment
plants as a means
of adding value to
re-refined lube
oil.
Designed as an
add-on or retrofit
to wipe film
evaporators these
units are equally
applicable to
other types of oil
refineries as a
final polishing
stage.
The CPS is based
upon banks of
active columns
that contain an
absorptive clay.
The physical
charasteristics of
the clay allow it
to be re-activated
once saturated,
and thereby
permitting several
hundred cycles to
be run before
being replaced.
Once exhausted,
typically of
6months to a year
of continuous, the
clay is disposed
off in a
conventional
landfill site. as
a dry
non-hazardous
waste. Average
lifetime costs of
clay per gallon of
oil processed is
US$ 0.02 at 2009
prices.
Processing oil
through the CPS
results in an oil
that is stable
against oxidation
over any measured
timescale - this
increase in shelf
life is an added
benefit of the
clay polishing
system.
Furthermore the
Viscosity Index is
not degraded by
the clay polishing
system.
Virtual
multi-pass
operations can be
achieved by a
single pass
through the CPS as
it is designed to
switch from
parallel to series
mode operation via
the custom SCADA
supplied with
every system. This
allows the plant
owner to easily
switch between
different
processing modes
for each oil
stream reclaimed
through the
front-end system.
Integration with
existing front-end
systems and/or
tank farms is
easily achieved
with the Redragon
CPS
