Column
Internals
Column internals are selected as per system requirements.
Column internals may be tray type or packings. We
can identify the most appropriate internal and design
the column for the given duty. |
|
| |
|
|
| |
 |
|
We
supply high quality structured packings with
appropriate internals through our associates.
The internals are designed to achieve high
degree of liquid distribution uniformity comparable
with the international standards. Packing
& internals are available in wide range
of materials. |
|
|
| |
|
|
| |
For several duties
trayed columns are the better choice. Synergy can
supply various Tray types like bubble cap, sieve,
and special designs for liquids containing solids. |

- Large diameter Columns
- Liquids containing solids/ fouling

- Complex columns
- Reactive distillation

- Corrosive systems (ceramic/plastic)
- Small diameter columns- low cost
situations

- High theoretical plates situations
- Low DP situations
- Revamps
- Small column diameters

Skid
Mounted Modular Units : for Distillation/Absorption/Evaporation
|
|
| |
|
|
| |
| For moderate
Distillation, Absorption or Evaporation
duties it is often Economical to supply
the process equipments like column,
heat exchangers, tanks, pumps and other
system components as a preassembled
skid mounted units. This ensures faster
project completion, minimum site work
and is most often economical for smaller
sizes.
Special Duty
Heat Exchangers as Distillation Column
Accessories or Otherwise |
| |
- Tubular exchangers
with twisted tape inserts for highly
viscous fluids.
- Heat exchangers
with Corrugated tubes for steam
condensing outside tube and turbulent
flow inside tube.
- Recirculating
bed heat exchangers for liquids
with severe fouling tendencies.
- Falling film
product cooler cum condenser (patent
applied for).
- Internal condensers
mounted on column top.
- Low hold-up
phase splitter (patent applied for).

Instrumentation
and Control Systems |
|
| |
|
|
| |
- We can offer total system integration of Instrumentation
and Control for plants engineered by us. Control
strategy and schemes will be designed for the
specific requirements of the project. Instrumentation
package based on International guidelines can
be devised and implemented using reliable instruments
and control elements. Different types of control
systems, from conventional control panel to
PLC based system with SCADA/ HMI or Distributed
Control System can be engineered and implemented.

Trouble shooting
/ Revamping/ modernization and other Services: |
|
| |
|
|
| |
- Some times distillation systems do not function
satisfactorily. The problems may be with column
or the associated system. This most often results
in to lower capacity, higher energy requirements,
purity problems or any other operational troubles.
Synergy when called for troubleshooting approaches
the problem is a systematic way to come out
with the most economical solution.
- Modernization or automation works.
