Crude Distillation
Unit (CDU): |
| |
This
is a mother unit in which crude oil is fractionated
into different products like light naphtha,
heavy naphtha, Lkero, Hkero, LGO and HGO by
distillation process.
The unit has major equipments like world's
tallest crude distillation column, fired heater,
network of heat exchangers, coolers and air
coolers, pumps, compressors and vessels.
The unit operation is fully automatic with
the most advanced instrumentation and control
system to ensure safe and the most energy
efficient operation. |
 |
| 2. |
Vacuum
Distillation Unit (VDU): |
| |
This is a
basic unit to upgrade the atmospheric residual
oil received from CDU through distillation
process carried out under vacuum and to derive
the products like vacuum distillate, LVGO,
HVGO and HHVGO.
The unit has major equipments like vacuum
distillation column, ejector system, fired
heater, pumps, vessels and the integrated
network of heat exchangers, coolers and air
coolers with CDU.

| 3. |
Visbreaker
Unit (VBU): |
| |
The vacuum
residue received from VDU is further upgraded
to derive more distillates by thermal cracking
process in this unit.
The thermal cracking takes place in the furnace
and distillates are obtained through two stage
distillation in atmospheric and vacuum distillation
columns.
|
 |
| 4. |
Fluid Catalytic
Cracking Unit (FCCU): |
| |
The LVGO and
HVGO (received from VDU) as well as gas oils
obtained from VBU are further upgraded into
useful products like LPG, gasoline, diesel
components, etc. through catalytic cracking
process carried out in the specially deigned
reactor in this unit.
The catalyst is also continuously regenerated
and reused in the unit to reduce production
cost drastically.
|
 |
| 5. |
Saturated
Gas Unit (SGU): |
| |
Refinery gases
and light naphtha steams are processed in
this unit to recover LPG components and reduce
gaseous losses such as to maximize LPG production. |
|
| 6. |
Naphtha
Hydrotreater and Catalytic Reformer Unit (NHT-CCR): |
| |
Naphtha produced
in the refinery is processed in this unit
to produce high octane blending component
to boost octane of the gasoline pool.
|
 |
| 7. |
Treating
Units: |
| |
The products
like LPG, gasoline, kerosene, ATF, diesel,
etc. obtained from various units in the refinery
undergo finishing treatments to meet the highest
quality standards for these products mainly
w.r.t. sulfur and olefins contents.
The refinery has following treating units:
a) Diesel Hydro Desulfurization Unit( Under
construction)
b) Kerosene Treating Unit
c) Gasoline Treating Unit
d) LPG Treating Unit
|
|
| 8. |
Environmental
Units: |
| |
The refinery
concerns for healthy environment are reflected
into incorporating the following units to
eliminate pollutants:
a) Sulfur Recovery Unit
b) Amine Wash and Regeneration Unit
c) Sour Water Stripping Unit
d) Spent Caustic Treatment System
e) Waste Water Treatment System
|
|
| 9. |
Support
Services Units: |
| |
The refinery
operation can be safe and sustained efficiently
mainly through following units:
a) Desalination and Demineralization Water
Unit
b) Cooling Towers
c) Nitrogen Generation Unit
d) Air Generation Unit (for plant and Instrument
air)
e) Fire Water System
f) Tempered Water System
g) Steam Generation Unit
h) Captive Power Plant
i) Crude Oil Storage
j) Products Storage
K)Products Loading, Unloading and Dispatch
Facilities
(see port and other infrastructure)

Automation
of Refinery Operation: |
| |
The operation
of the entire refinery involving all the process
units and all the facilities is made fully
automatic with the most advanced instrumentation
and control system to ensure safe and the
most energy efficient operation. |
