Against the backdrop of increasing global emphasis on environmental protection, oxygen enrichment membrane technology, as a green and clean oxygen production method, aligns with the concept of sustainable development. It provides various industries with a more environmentally friendly oxygen solution and helps promote the green upgrading of industries.
Oxygen enrichment membrane technology is an advanced gas separation method. Its core lies in using specially manufactured membranes that exploit differences in permeation rates of different gas molecules to enrich oxygen. The permeation process of gas molecules through a membrane can be broken down into several steps: adsorption, dissolution, diffusion, desorption, and release. Different gas molecules, due to differences in size, shape, polarity, and other properties, exhibit varying solubility and diffusion rates in the membrane material. Driven by pressure, when air passes through the membrane, oxygen molecules, having a faster permeation rate, quickly penetrate the membrane wall and become enriched on the other side, achieving an oxygen content of 27–45%.
Advantages of membrane-based oxygen enrichment technology:
Simple operation: The technology does not require complex equipment or process flows. Oxygen enrichment is achieved simply by passing air through a device equipped with oxygen enrichment membranes.
Low energy consumption: Compared with traditional oxygen production methods such as cryogenic separation, oxygen enrichment membrane technology does not consume large amounts of energy to liquefy and separate air, thus offering lower energy consumption.
Low maintenance cost: Due to the relatively simple equipment, the absence of complex moving parts, and the lack of extreme conditions such as high temperature and high pressure, maintenance costs are low and operational reliability is high.
Application fields
Oxygen enrichment membrane technology is currently used in small oxygen concentrators, environmental oxygen enrichment, oxygen enriched air conditioning, oxygen enriched combustion in kilns and boilers, and oxygen enriched combustion in engines.
Medical and healthcare: In hospitals, oxygen enriched by gas separation membrane technology can be used for oxygen therapy in patients, providing high concentration oxygen for those with respiratory diseases, cardiovascular diseases, etc., thereby improving their breathing condition and physical function.
Industrial production: Industries such as steel, chemicals, and glass require high purity oxygen for combustion, oxidation, and other processes. Gas separation membrane technology can provide cost effective oxygen enrichment solutions for these industrial productions, improving production efficiency, reducing energy consumption, and lowering environmental pollution.
Aerospace: In aircraft cabin environmental control systems, gas separation membrane technology can enrich oxygen from air to provide a safe and comfortable breathing environment for pilots and passengers. Additionally, in spacecraft life support systems, membrane separation technology can also be used for oxygen regeneration and enrichment.
