DESCRIPTION
OF THE PROCESS
Each
of the processes works in the following way:
|
|
|
|
UNLOADING
AND RECEPTION |
|
| All
used oil is received in cistern lorries, analyzed
and classified. According to the results, it is
passed on to the conditioning
unit or to rejection |
|
 |
 |
|
|
|
|
REJECTION |
|
All
used oil that is NOT SUITABLE for re-refining
is rejected, this may be due to: |
|
 |
presence
of PCB’s |
|
other
pollutants |
|
 |
|
Rejected
oil is referred to an authorized waste manager. |
|
|
|
|
|
CONDITIONING |
|
Storage
of used oil SUITABLE for the re-refining
process. |
|
This
oil is treated in the following way: |
|
|
water
settling |
|
centrifuging |
|
preheating
for feeding to plant |
|
|
|
|
|
|
DISTILLATION
|
|
The
used oil is passed on to distillation and fractionating
through a series of modules. From this part the following
are obtained: |
|
 |
|
water
is treated in a WWTP
|
|
spindle
|
|
distilled
oils |
|
asphalt
bitumen, that is used for manufacturing
waterproofing materials or asphalt for roads.
|
 |
|
|
|
|
|
|
|
|
FINAL
TREATMENT |
|
The
distilled oils and spindle are received and conditioned,
thus producing: |
|
|
distilled
oils : top quality base oils, that are
commercialized to manufacturers of lubricants,
to generate new motor and industrial lubricants. |
 |
 |
|
|
|
spindle,
that is used to generate
plant energy – self-consumption |
|
|
|
|
|
|
SALTS |
|
Receives
the reaction water from the final
treatment from which salts suitable for
use as fertilizers are produced, which are commercialized
to fertilizer manufacturers. |
|
|
|
|
|
WWTP |
|
Wastewater
treatment plant, the wastewater comes from: |
|
|
|
Once
this water has been treated, it is used in the plant's
refrigeration systems (self-consumption) |
|
|
|
|
|
HEAT
GENERATION |
|
Produces
the necessary energy (heat) for all processes. It uses
the spindle produced in the plant as fuel once it has
been conditioned. |
