Manufacturing Process of Oxygen Plants

Compression Of Atmospheric Air By Air Compressor

The free saturated air is sucked from atmosphere through a highly efficient dry-type suction filter into the first stage of the horizontal balanced opposed, lubricated reciprocating air compressor. Compressed air is chilled to 12 degree centigrade in a chilling unit at 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 By Process Skid

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.

Cooling Of Air By Expansion Engine (Expander)

The process air before liquefication in the air separation unit needs to be cooled to temperatures sub-zero (cryogenic). The main portion of the air after the process skid enters the expansion engine through the heat exchanger no. I after pre-cooling. The temperature of the air drops to around -165degC by the Expander which is a very highly efficient advanced design with Teflon piston rings and completely hydraulic mechanism with leakproof ball valves

Separation Liquid Air Into Oxygen And Nitrogen By Air Separation Column

Chilled, Oil free 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 LO Pump

Compression/Withdrawal And Filling Of Oxygen And Nitrogen

The free saturated air is sucked from atmosphere through a highly efficient dry-type suction filter into the first stage of the horizontal balanced opposed, lubricated reciprocating air compressor. Compresssed air is chilled to 12 degree centigrade in a chilling 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
