Output, purity and pressure
| Flow (Nm3/h) | Purity | Pressure MPa(G) | Subcooled (K) |
LA | 2260 | Same as the feed air | 0.5 | 284.15 |
Note: 1. Nm3/h is defined as the volume at 0℃, 101.3kPa(A) (same as below);
2. The liquid output is calculated from data of gas, and the pressure is calculated with 0 meter high at outlet of cold box.
3. All pressures not specially defined below are the gauge pressures.
Description:
The proposed plant employs a process in which air is purified by molecular sieve and refrigerated by refrigeration boosting turbine single expander.
The feed air sucked through air intake is cleaned of dust and other mechanical impurities in air filter AF and compressed to a pressure by air compressor. The compressed air flows into air precooling system for temperature to be reduced.
The air comes from the air precooling system flows into switched molecular sieve adsorber where such impurities as moisture, CO2, C2H2 and other impurities are adsorbed by molecular sieve.
The purified air is divided into 2 streams: one stream to be as instrument air, and another stream enters the boosting end of expander to be boosted, and then enters main heat exchanger to be cooled. When the air is cooled to 252.2K, it enters the chiller to be cooled to 243K, and then it enters the main heat exchanger. The cooled gas is divided into two streams: one stream enters the expander to be expanded, and part of expanded air is as refluxed air goes back to the front of feed air compressor after rewarmed in main heat exchanger; another part of air is continuously cooled to liquefaction in the main heat exchanger, and the liquefaction air out of heat exchanger enters into gas-liquid separator, and then it is sent to the liquid air storage system after being throttled.
Applications:
1. Refrigerant
2. Extract liquid oxygen , liquid nitrogen and rare gas
3. Automotive, Ship, Aerospace & Aeronautics Industries
4. Aerospace
5. Chemical synthesis
6. Welding and metal processing
Competitive Advantage:
1. The air pre-cooling system is equipped with air cooling column which can effectively wash off feed air such acid matters as SO2,NOx,HCl,Cl2 harmful to molecular sieve so as to guarantee the service life of molecular sieve.
2. process with molecular sieve for purification employed by this air separation is an experienced process which is easy to operate. The main equipments in cryogenic cold box are low pressure ones so as to ensure the high reliability and handy maintenance.
3. Such maintainability as convenience dismantlement and mounting of the parts which need repair is considered in design.
4. The low temperature parts can be maintained at the normal temperature end. Such outdoor parts as fasteners for cold box plates are all made of stainless steel or brass.
5. Perfect technology R&D system
6. Low power consumption
