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.

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. |

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. |

| 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 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.
