PROCESS
Air Compressor
and Chilling Unit
The
free saturated air is sucked from atmosphere through a highly efficient dry-type
suctionfilter into the first stage of the horizontal balanced opposed, lubricated
reciprocating air compressor. Compresssed air is chilled to 12 degree centigrade
in achilling unit ata temperature of 12 degree centigrade to a moisture separator
where the condensed moisture gets removed before entering into Molecular Sieve
Battery. Before sending the air to MOLECULAR SIEVE BATTERY, air is passed through
an OIL ABSORBER where air becomes oil free.
Purification of Air
Chilled air passes through the Molecular Sieve Battery consisting of Twin
Tower packed with Molecular Sieves to remove moisture and Carbon dioxide present
in the air.
Molecular Sieve Battery operates on Twin Tower System, when one
tower is under production the other tower is regenerated by passing waste Nitrogen
gas at 200 degC through a reactivation heater. After interval of 8 to 10 hours,
the tower under production gets exhausted and regenerated by similar process before
use and thus the cycle continues. Any dust particles gets filtered in the DUST
FILTER before air enters the AIR SEPARATION COLUMN.
Air Separation
Chilled, Oilfree and moisture free air
enters into multi-pass HEAT EXCHANGER NO.I where it gets cooled to (-80) degC
by cold gained from outgoing waste Nitrogen and Oxygen.
A
part of air this enters a multi-pass HEAT EXCHANGER NO. II or LIQUIFIER made of
special Alloy tubes. This air cools to (-170) degC before passing through an expansion
valve. Due to joule Thompson Effect, after the expansion valve. Due to joule Thompson
Effect, after the expansion valve, air gets further cooled down and gets liquified
before entering into bottom column is known as RICH LIQUID.
THE RICH LIQUID
in the BOTTOM COLUMN enters into feed tray of top column enters into feed tray
of top column. Similarly the liquid nitrogen called POOR LIQUID enters into top
column as a reflux & it takes away the latest heat of condensing Oxygen and
gets vapourised whereas the liquid Oxygen flows down the trays of the TOP COLUMN
into the Condenser passes through a SUB-COOLER to a LIQUID OXYGEN PUMP.
Cylinder Filling Liquid oxygen pump pumps Liquid Oxygen through
heat exchanger no. II and I, where liquid Oxygen gets gasified before filling
in Cylinders in the FILLING MANIFOLD.
The pure bone dry Oxygen gas at ambient
temperature and high pressure is filled into OXYGEN CYLINDERS through manifold
valves by means of the highly efficient reciprocating LIQUID OXYGEN PUMP.
Nitrogen Production Nitrogen can be produced with
in gaseous as well as liquid form simultaneously without additional cost. Both
commercial as well as technical grade can be produced.

RANGE OF PRODUCTS Oxygen/Nitrogen & Acetylene
Plants Oxygen/Nitrogen Plant: Oxygen plants are available
in capacities from 20 to 500m3/Hr suitable for producing industrial and medical
oxygen upto 99.9% purity. Nitrogen is available as a second product from the oxygen
plant in approximately four times the quantity of oxygen produced. Standard purity
of nitrogen is 96% to 99.5% but are available upto 99.999% also.
Oxygen
gas filling in Cylinders: 
The oxygen plant has a built in gas vaporizer and an integral liquid oxygen filling
pump to fill oxygen gas from liquid oxygen in the air seperation unit directly
into cylinders upto pressure of 155 Bar (200 Bar optional)
Nitrogen
gas filling in Cylinders: Nitrogen gas can be filled in cylinders
directly up to 155 Bar (200 bar optional) simultaneously with the oxygen production
by an additional LIQUID NITROGEN PUMP provided with a Nitrogen exchanger in the
air seperation unit. The nitrogen gas can also be filled from the outlet of the
cold box by installing a nitrogen compressor up to 155 Bar.
Liquid
Nitrogen Output: All our Oxygen and Nitrogen plants can give Liquid
Nitrogen output.
