Main functions and working principles

Oxygen production equipment separates and extracts oxygen from the air through different technologies. The main technology used is pressure swing adsorption (PSA) technology.

The principle of oxygen production by pressure swing adsorption is to separate nitrogen and oxygen in the air based on the different adsorption capacities of molecular sieves for nitrogen and oxygen and the characteristics that the adsorption capacity changes with pressure. Zeolite molecular sieves (ZMS) preferentially adsorb nitrogen at room temperature and pressure. As the pressure increases, the adsorption capacity of nitrogen increases. Nitrogen is adsorbed under pressure. When the molecular sieve is saturated with adsorption, the pressure is reduced and the nitrogen is desorbed. By controlling the pressure change, the adsorption, desorption and adsorption cycle is carried out, thereby continuously separating oxygen and nitrogen to prepare oxygen-rich gas. The separation mechanism of oxygen production by pressure swing adsorption is equilibrium separation type, and its basic working steps are:

Pressure adsorption

Under the adsorption pressure state, the air mixture to be separated is introduced into one end of the adsorption bed, and the molecular sieve selectively absorbs the nitrogen component in the mixed gas, and the remaining components flow out at the other end of the adsorption bed.

Decompression desorption

According to the performance of the nitrogen component, one or more of the pressure reduction, flushing, and vacuuming methods are selected to desorb the nitrogen component in the molecular sieve, thereby regenerating the molecular sieve. Generally, the desorption process is to first reduce the pressure to normal pressure, and then regenerate the molecular sieve by flushing, vacuuming, or replacement.

Increase the pressure

After the molecular sieve completes the regeneration process, the oxygen component is introduced into one end of the adsorption bed for pressurization until the pressure in the adsorption bed reaches the adsorption pressure state. Then enter the pressure adsorption state (step 1), and the cycle process is completed. The specific process of the pressure swing adsorption oxygen production cycle is shown in Figure 2-1.

The pressure is increased at room temperature and pressure. At the adsorption pressure, the molecular sieve adsorbs nitrogen and flows out oxygen. Then, the pressure is equalized to reduce the pressure and release some of the unflowing oxygen. Then, the pressure is reduced in the adsorption direction and the oxygen is used as the flushing gas for other adsorption towers. The pressure is reduced against the adsorption direction to release the desorbed nitrogen so that the molecular sieve is partially regenerated. The flushing gas released from other adsorption towers is used to flush the adsorption bed so that the molecular sieve is fully regenerated. The pressure in the adsorption tower is increased until the adsorption pressure is reached, completing the cycle.

Features and advantages of oxygen generation plant

Energy-saving

he oxygen production unit focuses on energy-saving in design and engineering, aiming to maximize the use of energy resources, thereby reducing operating costs and improving economic benefits. The key lies in the use of advanced compression and separation technologies, which effectively reduce energy consumption by optimizing the operating process and equipment design. For example, precise control of the operating parameters of the compressor and optimization of the adsorption process can significantly reduce power consumption and heat energy loss, and improve overall energy utilization efficiency.

Compliance with strict safety standards

In addition, the design of the oxygen production unit meets strict safety standards, providing reliable protection for the operation of the equipment. The device is equipped with multiple safety protection measures, such as pressure sensor monitoring and automatic pressure relief devices, to ensure timely decompression under abnormal conditions and keep the system safe and stable. At the same time, the equipment is also equipped with an automatic alarm system that can detect and respond to abnormal oxygen purity, ensure that the oxygen supply meets medical and industrial standards, and ensure the safety of users.

Modular design

Modular design is another important feature of the oxygen production unit, which enables the equipment to be flexibly expanded or reduced according to demand. Through the modular structure, users can customize the configuration according to specific production needs and space constraints, whether in medical institutions, industrial production lines or temporary emergency sites, and can effectively adapt. In addition, the modular design simplifies the installation and maintenance process of the equipment, reduces downtime and maintenance costs, and improves the overall reliability and maintainability of the equipment.
