1. Cryogenic Air Separation Series Working principle

The basic principle of air separation is to use low temperature distillation to condense the air into a liquid and separate the air according to the evaporation temperature of each component. Two-stage distillation tower at the top and bottom of the upper tower to obtain pure nitrogen and pure oxygen at the same time; can also be in the main cold evaporation side and condensation side respectively out of liquid oxygen and liquid nitrogen. The air separation in the distillation tower is divided into two stages, the air is separated for the first time in the lower tower to obtain liquid nitrogen and at the same time to obtain oxygen-rich liquid air; oxygen-rich liquid air is sent to the upper tower for distillation to obtain pure oxygen and pure nitrogen. The upper tower is divided into two sections: the liquid air inlet as the boundary, the upper part of the distillation section, distillation of rising gas, recovery of oxygen components, purification of nitrogen purity, the lower part of the distillation section, the liquid nitrogen components to separate out, to improve the oxygen purity of the liquid.

2. Cryogenic Air Separation Series Workflow

1.Air compression: The air is compressed by the compressor to 0.8-1.OMpa;

2.Pre-cooling: The air is pre-cooled to 5-10°C in the pre-cooling unit and the moisture is separated;

3.Purification: air is removed from the molecular sieve purifier to remove residual moisture, carbon dioxide 4.and hydrocarbons; air expansion: air is expanded in an expander to cool the unit and provide the required cooling capacity;

5.Heat transfer: The air is heat exchanged with the refluxed oxygen, nitrogen and dirty nitrogen in the fractionator heat exchanger and is cooled close to the liquefaction temperature and the refluxed oxygen, nitrogen and dirty nitrogen is repeatedly heat exchanged to ambient temperature;

6.Subcooling: liquid air and liquid nitrogen before subcooling throttling in a subcooler;

7.Distillation:The air is separated by distillation in the distillation column to obtain the product nitrogen at the top of the upper column and the product oxygen at the bottom of the upper column.

Systems can be customised to meet customer production requirements

1.Air Compression Systems

Centrifugal air compressor, high efficiency, low consumption, stable and reliable operation.

2.Pre-cooled unit systems

The original imported screw refrigeration compressor and all imported refrigeration components are used in the air conditioning unit, and the water separator, manual and imported automatic drainage, is set to remove the accumulated water at regular intervals.

3. Automatic Air purification systems

The purifier is a vertical single bed with simple and reliable structure and low resistance loss; built-in filter, blowing out and purifier regeneration at the same time. High efficiency electric heater to ensure thorough regeneration of the molecular sieve.

4. Pressurised turbine expansion systems

Turbine expander with gas bearing, simple and reliable, easy to operate, high efficiency when waiting for time. The expander's cold box is set up separately for easy maintenance.

5. Fractionating tower system (cold box)

Fractionation tower heating, cooling, liquid accumulation and purification in one go, simple and fast operation. Using aluminium plate fin heat exchanger, aluminium convection sieve tower, the whole fractionation tower equipment pipeline using argon arc welding, cold box tower and the main pipeline, using high-strength aluminium alloy material or stainless steel material, in order to increase the strength, reduce the torsional damage of the pipeline. Cold box equipment bracket, pipeline and valve bracket should be used stainless steel or aluminium alloy material. The cold box is insulated with pearlescent sand and slag wool to ensure minimum cold loss. The structure of the cold box ensures the overall strength and requirements of earthquake and wind resistance to ensure the load-bearing capacity of the cold box; the cold box is equipped with sealed gas protection and safety devices during operation; the main equipment in the cold box is set up with electrostatic grounding; the cold valve and pipe connections in the cold box are all welded, avoiding the use of flange connections.

6.O2, N2, Ar pressurised charging system

Single gas production: internal compression process (cryogenic liquid pump, high pressure gasifier, filling row) Multi-gas production: external compression process (oxygen & nitrogen & argon booster, filling row)

7.Instrumentation and control systems

Siemens imported brand, fully automatic production system, digital control system

Equipment layout drawings (according to civil design), process piping design drawings, instrumentation electrical design drawings, etc.

FAQ Whatsapp:008618936889762

1. Q: Can you provide the drawings of your plant/tanks?

Normally, our drawings will be provided to our customer only after the order is confirmed. However, we can provide you some drawings which belong to our old customers for reference. By the way, here, I need to remind you that our company only provides the engineering design drawings and the civil design drawings will be out of our range. Because every place has different situation, your side needs to find civil design company in your local market to do the drawings according to your specified environment.

2. Q: How’s the producing time and delivery time??

Normally, our production time is 6 months for air separation plants but it also depends on the capacity you require. The
bigger the plant, the longer time for production. Please also note that when the plant is finished, we need to wait for bulk vessel. It’s very common to wait for one or two months to find the right vessel.
The delivery date is 3-5 months.

3. Q: What about warranty?

Equipment warranty is 12 months from the date on which the equipment is applied successfully into operation, or 14 months from the date on which the equipment has been delivered, whichever comes first.
Generally speaking, our air separation unit can work normally for 15-20 years if it is maintained properly. As a leading brand in China with over 40 years history, reliability and stability of our ASU is much better than small young companies.
