| 1 | Air Compression System | After the raw air is filtered, it is compressed to ~0.5 MPa by the air compressor. ~0.5 MPa |
| 2 | Circulating booster system | 2.8~3.0MPa,. |
| 3 | Pre-cooling System | Reduce the temperature of compressed air to about 8~10 ° C8~10ºC |
| 4 | Air Purification System | Removing the remained moisture, carbon dioxide and hydrocarbons of compressed air in the molecular sieve adsorber. |
| 5 | Distillation System (Cold Box) | Distillation system is the key to realize air separation. It mainly uses the boiling point difference of different gas components to separate. Under low temperature and appropriate pressure conditions, liquid air is partially vaporized and partially condensed in the distillation column for many times. |
| 6 | Turbo Expander System | The air expands and cools in the turbo expander and provides the cooling capacity required by the device. ,,,. |
| 7 | Storage and vaporization System | Store the separated liquid products, such as liquid oxygen, liquid nitrogen, and liquid argon. When the air separation unit is under maintenance, overhaul, or short-term failure occurs, the stored liquid products can be vaporized and continue to be supplied to ensure that the production process will not be seriously affected by gas supply interruptions. |
| 8 | Instrument Control System | The instrument control system can accurately measure and monitor various process parameters of the air separation unit, and control and adjust the air separation unit according to the measured parameters. When the process parameters exceed the normal range, an alarm signal will be issued and interlocking measures will be taken. Various data in the operation process recorded by the instrument control system can facilitate operators and managers to analyze and diagnose the operation of the device. |
| 9 | Electrical Control System | The electrical control system is responsible for providing power to all electrical appliances of the air separation unit and distributing power reasonably. For various equipment motors of the air separation unit, the electrical control system can realize the control functions of motor start, stop, speed regulation, etc., and protect the motor on the basis of monitoring the running status of the electrical equipment. |
