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
