Product Introduction
Products Description:
What is ASU
Liquid air separation equipment requires more cooling capacity than gas air separation equipment. The Whole device can be controlled bt DCS or PLC system. Following your specific require to design the machine, liquid phase or gaseous phase, the production of each product. Full set production line which is automatic.
| NO. | MAIN PART | FUNCTION |
| 1 | Air Compression System |
Air be compressed to 0.5-0.7 Mpa by air compressor, Imported centrifugal air compressor, high efficiency, low consumption, stable
and reliable operation
|
| 2 | Pre-cooling System |
The air is pre-cooled to 5-10℃ in the pre-cooling unit, and the moisture is separated. The original imported screw refrigeration
compressor and the air-conditioning unit combined with all imported refrigeration components are equipped with a water separator,
manual and imported automatic drains to drain water regularly.
|
| 3 | Air Purification System |
Removing the remained moisture, carbon dioxide and hydrocarbons of compressed air in the molecular sieve purifier. The purifier
adopts a vertical single-layer bed with simple and reliable structure and low resistance loss; built-in filter, blowing off and
purifier regeneration at the same time; high-efficiency electric heater ensures complete regeneration of molecular sieve
|
| 4 | Fractionating Column System (Cold Box) |
The heating, cooling, liquid accumulation and purification of the fractionating tower can be completed in one way, and the
operation is simple, quick and easy. Adopt aluminum plate-fin heat exchanger, aluminum convection sieve plate tower, the entire
fractionating tower equipment pipeline adopts argon arc welding, the tower body and main pipeline in the cold box are made of
high-strength aluminum alloy or stainless steel to increase the strength , Reduce the torsion damage of the pipeline. The
equipment brackets, pipes and valve brackets in the cold box shall be made of stainless steel or aluminum alloy. The cold box is
insulated with pearl sand and slag wool to ensure that the loss of cold capacity is minimized. The cold box structure guarantees
the overall strength and the requirements of anti-seismic and wind resistance, and guarantees the load-bearing capacity of the
cold box. When the cold box is running, it is equipped with airtight protection and safety devices. The main equipment in the cold
box is equipped with electrostatic grounding. The cold valve and pipeline in the cold box all connections are welded, and flange
connections are avoided.
|
| 5 | Turbo Expander System |
The air expands and cools in the turbo expander and provides the cooling capacity required by the device.The turbo expander adopts
gas bearing, which is simple and reliable, easy to operate, and high efficiency. The cold box of the expander is set separately
for easy maintenance.
|
| 6 | Turbo Expander System |
The air exchanges heat with the refluxing oxygen, nitrogen, and dirty nitrogen in the heat exchanger of the fractionation tower,
and is cooled close to the liquefaction temperature, and the refluxed oxygen, nitrogen, and dirty nitrogen are repeatedly heat
exchanged to the ambient temperature;

| 7 | Filling System |
Single gas production: Internal compression process ( Cryogenic liquid pump, High pressure vaporizer, Filling manifold).Multi-gas
production: External compression process (Oxygen & nitrogen & argon booster, Filling manifold).
|
| 8 | Instrument and Electric Control System | Siemens imported brand, Fully automatic production system, Digital control system |
| 9 | Others |
Equipment layout drawing (according to civil engineering design), Process pipe design drawings, Instrument electrical design
drawings, etc.
