Liquid Oxygen Plants

PROCESS DESCRIPTION:

STEP I: Air is sucked by a multi stage air compressor and passed through the following stages.

STEP II: COMPRESSION OF AIR

This is performed by the multistage highly efficient air compressor.

STEP III: PURIFICATION OF AIR

This is performed by the Process Skid.

STEP IV: COOLING & LIQUIFICATION OF AIR

This is performed by a highly efficient expansion engine and also by a refrigeration unit (for 100% liquid output).

STEP V: AIR SEPARATION (RECTIFICATION)

This is performed by the special AIR SEPARATION UNIT consisting of upper column, lower column and special exchangers. The separation air is by the CRYOGENIC PROCESS. The final product from a liquid Oxygen/Nitrogen goes to the storage tank.

STEP VI: CRYOGENIC STORAGE TANKS

Cryogenic Vessels are designed for storage and transport of liquid gases at sub-zero temperatures. Manufacturing of such cryogenic tanks requires special technical know how and sophisticated fabrication techniques. We have developed the necessary technology and has been manufacturing cryogenic vessels.

Air Compressor

This is a multi stage, heavy duty water-cooled air compressor for 24 hours operation, horizontal type complete with fly wheel inter cooler, foundation bolts, motor pulley, motor, v belt, guard and slide rails. This is used to compress atmospheric air.

Air Purifier / Process Skid

This consists of the following Parts:

1) After cooler with tank
2) Nitrogen cooler with tank
3) Moisture separators
4) Chilling units with Freon unit
5) Oil absorber filled with alumina
6) Molecular sieve batteries on skid
7) Defrost heaters
8) Gas/Air/water line as per standard layout on skid /platform prefabricated and ready for installation
9) Water pump
10) Inlet & outlet water lines
11) Drain manifold complete with ball valves for draining moisture. All the above equipments are properly mounted on skid /platform complete with interconnecting piping and ready for installation

Expansion Engine

Complete with branded motor/starter of Siemens / ABB world class quality. Expansion Engine is complete with hydraulic valve control, bursting disc for safety, complete with fly wheel pressure gauge, motor pulley V belt, Belt guard, slide rails inter connected pipes (inlet and outlet)

Air Separation Column - Cold Box

This consist of the complete cold box (outer steel casing) complete with top column, bottom column, condenser, sub-cooler, re-boiler, exchanger 1, exchanger 2, control panel, instruments, pressure gauges, digital automatic temperature scanner with pt-100 sensors, expansion valves, analysis valves, inlet & outlet, air oxygen and nitrogen, gas lines with control valves neatly mounted and firmly fixed on the cold box.

STAINLESS STEEL IS REQUIRED FOR HOSPITAL OXYGEN, FOOD GRADE QUALITY AND ALSO TO MAKE EXPLOSION PROOF.

NOTE: OLD TYPE OF COPPER VESSELS/COLUMNS/TRAYS LIKE CHINESE AND LOCAL TYPE DISCONTINUED 10 YEARS BACK.
Liquid Oxygen Pump

Horizontal single acting pump with Piston, Piston Rings - oil free - Teflon with guide ring, Safety Devices, Non-Return Valves, Motor with Pulley, V-Belts, Belt Guard, Inter Connecting Pipes with ducting to cold box suitable for filling Oxygen

High Pressure Filling Manifold

For filling high-pressure Oxygen to Cylinders. It consists of main High Pressure Isolation Valve and Pigtail filling connection with individual regulation Valve with Pressure Gauge and Safety Relief Valve.
