What is the most common method for air separation?

Air separation is most commonly achieved through refrigeration and distillation. This method is based on the differences in boiling points of different components at different temperatures and uses the principles of condensation and vaporization for gas separation.

Specifically, commonly used air separation methods include the following steps:

1. Compression: Compress air in the atmosphere through a compressor to increase gas density and pressure.

2. Precooling: Pass the compressed air into air coolers (precoolers) to cool it under normal pressure and condense the water vapor in it.

3. Expansion (expander or expansion valve): Pass the cooled gas through the expansion device to reduce both the pressure and temperature.

4. Separation: Pass the expanded gas into a separation device, usually a distillation tower or adsorption column.

    a. Distillation method: Separation using the differences in boiling points of different components in the air. In the distillation column, the temperature is gradually increased, causing the different components to vaporize and condense respectively, thereby separating oxygen, nitrogen and other inert gases.

    b. Adsorption method: Use an adsorbent, such as activated carbon, to selectively adsorb certain components. By changing pressure and temperature, the adsorbent can adsorb and desorb to achieve gas separation.

5. Product collection: After separation, the pure oxygen and pure nitrogen obtained are collected separately for further processing and storage.

This air separation method produces high-purity oxygen and nitrogen for use in many applications such as medical, industrial and scientific research.

What is the difference between cryogenic oxygen and PSA?

 

Low-Temperature Oxygen and PSA (Pressure Swing Adsorption) are two common air separation technologies.

 

Low-temperature oxygen is used to separate oxygen and nitrogen in the air through low-temperature fractionation. The process exploits differences in the boiling points of air to separate gas components by cooling the air to a liquefied state and then gradually raising the temperature. Under low temperature conditions, oxygen in the air liquefies earlier, while nitrogen remains in a gaseous state. The liquid oxygen is then separated by distillation and collected.

 

 PSA uses the selective adsorption properties of adsorbents to separate oxygen and nitrogen. In the PSA oxygen generator process, air passes through a pressure swing adsorption tower composed of adsorbents. Adsorbents have different adsorption capacities for oxygen and nitrogen. During the adsorption stage, the adsorbent selectively adsorbs nitrogen while oxygen passes through. Then, during the pressure shift phase, the pressure is reduced so that the adsorbent releases the adsorbed nitrogen, making it available for adsorption sites again.

 

 Therefore, cryogenic oxygen and PSA are two different air separation processes. Low-temperature oxygen mainly relies on the boiling point difference of the gas, while PSA nitrogen generator uses the selective adsorption of the gas by the adsorbent to achieve separation. The choice of which process to use depends on the needs and technical requirements of the specific application.

Frequently Questions about the Construction of Lightning Protection Projects

Lightning protection projects and facilities must be installed inside and outside the building to prevent lightning intrusion. However, problems of varying degrees will occur during the actual construction process, including the following situations;
1. Construction not according to drawings
According to regulations, during the construction of buildings, construction should be carried out in strict accordance with the construction drawings that have passed technical review. It is not allowed to add or delete items at will, cut corners, etc. However, during the inspection of the lightning protection device  construction site, it was found that some projects were not carried out according to the design drawings. During construction, the distance between the down conductors set exceeds the design range, and the down conductors are not set at the corners of the building.
2. Irregular welding of lightning protection device
Lightning protection grounding welding of buildings always accompanies the whole process of construction. The quality of welding directly determines the quality of lightning protection projects. In building design, basic steel mesh is often used as the grounding body. In actual inspection, problems existing in it are: Welding, the welding between the main steel bars of the down conductor and the grounding body, and the welding between the main bars of the ground beam, the overlap length often does not meet the specified standards; the specifications of the lap steel bars do not meet the requirements.
3. No reserved points for equipotential connection
The lightning protection effect of a building mainly depends on whether the equipotential connections formed between the non-charged metal objects and the charged metal objects in the building can become a unified whole. Therefore, during the construction process of the building, the equipotential reserve end should be set with enough points at necessary locations as reserves.
4. Failure to install surge protector as required

The settings of surge protectors, low-voltage power distribution grounding forms, shielding measures, installation techniques, and pipeline laying are inconsistent with the standard requirements for lightning protection design. The low-voltage power distribution system introduced into the building should be installed with corresponding surge protectors and floor lighting systems (electrical equipment). Surge protectors should be installed in the power control cabinet. Cable TV, broadband network, and telephone lines in buildings should be equipped with signal arresters when entering the building.

Lightning protection construction pictures

 

Jinli  is a company integrating R&D, production, and sales. Since its establishment in 2006, it has 18 years of experience in producing surge protectors. The lightning protection department consists of a technical department and a construction department.

Why are large and medium-sized air separation equipment suitable for using full low-pressure processes?

Reducing the working pressure of the air separation equipment can reduce the unit energy consumption of the product. The working pressure of the full low-pressure air separation equipment is close to the working pressure of the lower tower, while the working pressure of the small air separation equipment is much higher than the pressure of the lower tower. The working pressure is low, and the unit cooling capacity generated by expansion is also small. In order to maintain the balance of cooling capacity, it is first required that the unit cooling loss is also small. For large-scale air separation equipment, the unit cooling loss decreases as the unit capacity increases. At the same time, a smaller hot end temperature difference is also selected during design. The unit cooling loss due to incomplete heat exchange is relatively small, which is a good way to reduce the working pressure. Favorable conditions were created.

 

In addition, the low working pressure requires the expander to have high efficiency so that it can produce a larger cooling capacity under the same pressure difference. As the capacity of the turboexpander increases, the optimal rotation speed decreases and the efficiency increases. Therefore, it is most suitable for large-scale air separation equipment, making it possible to reduce working pressure.

 

For small air separation equipment, the cooling loss is relatively large. Even if a turbine expander is used, the speed is as high as 105r/min or more, the efficiency is low, and the maintenance and management requirements are very high. In addition, for large-scale air separation equipment, the amount of expansion is small relative to the amount of process air. The expanded and refrigerated air can still participate in distillation and extract oxygen from it. If a small air separation equipment adopts a low-pressure process, because the amount of expansion gas required to generate refrigeration capacity is large and cannot be fully involved in the distillation, the oxygen extraction rate will be very low, and the energy consumption per unit product will still be high. Therefore, the full low-pressure process is most suitable for large and medium-sized air separation plants.

 

At present, with the adoption of molecular sieve adsorption purification and booster turbine processes, as well as the advancement of plate-fin heat exchanger technology, the minimum capacity of low-pressure air separation equipment has been designed to 340m3/h oxygen production and 800m3/h nitrogen production (KDON -340/800), the exhaust pressure of the air compressor is 0.59MPa.

What is the pressure swing adsorption molecular sieve purification process?

What is the pressure swing adsorption molecular sieve purification process, and what are its characteristics compared with the temperature swing adsorption purification process?

Molecular sieves have the function of selective adsorption of mixed gases, and their adsorption capacity changes with changes in temperature and pressure. Its adsorption capacity increases at low temperature and high pressure, and decreases at high temperature and low pressure. Temperature swing adsorption (TSA) is based on the principle that molecular sieves adsorb at room temperature and desorb at high temperatures, while pressure swing adsorption (PSA) is based on the principle that molecular sieves adsorb at high pressure and desorb at low pressure.

The so-called pressure swing adsorption molecular sieve purification process is to use the molecular sieve pressure swing adsorption process to remove water, carbon dioxide, and hydrocarbons in the air, eliminating the need for air pre-cooling systems and regeneration heaters, as shown in Figure 15.

Use 1% to 1.5% purified air to regenerate molecular sieves. The general switching cycle is 9 to 14 minutes. There are 2 to 6 adsorbers according to the specifications of the air separation unit. The adsorbent capacity is 4 times that of the TSA adsorbent of similar air separation units. Each adsorbent is The container is equipped with 6 switching valves.

Compared with TSA, the advantages of PSA are:

     1) Simplify the process and eliminate the need for equipment such as air cooling towers, evaporative cooling towers, low-temperature water pumps, and regenerative heaters;

     2) There is no steam consumption required for TSA heating regeneration. For a 60,000m3/h air separation unit, 1,800kg/h of steam (approximately 1,000kW·h/h) can be saved.

Its disadvantages are:

     1) Air switching loss is 1% to 1.5% and consumes 400kW more power;

     2) The switching cycle is short and the switching valve is prone to failure;

     3) It is difficult to completely desorb the regenerated molecular sieve at room temperature, which will affect the adsorption performance of the molecular sieve and bring some harmful gases into the air separation unit, which will have a certain impact on the safety of large-scale air separation units;

     4) The investment is slightly larger.
