When mixed gases flow through a polymer membrane, they separate based on their different permeation rates due to variations in solubility and diffusion coefficients. Gases like water, oxygen, and carbon dioxide with faster permeation rates pass through and get enriched on one side, while gases like nitrogen and argon with slower permeation rates gather on the other side. This process achieves gas separation. When using pressurized purified air, it enriches inert gases like nitrogen into high-purity nitrogen-rich gas, removing oxygen-enriched air from the permeate side. Compared to other methods, membrane nitrogen enrichment is advantageous due to its simplicity, continuous operation, and stability.
Advantages of Separation Membrane Technology
1). Advanced technology, the latest technology of normal temperature air separation;
2). No noise, completely static operation, meeting environmental protection requirements;
3). No moving parts, less equipment maintenance;
4). High reliability of continuous operation and long service life of equipment, up to more than 10 years;
5). The capacity expansion is simple, just need to add membrane parts in parallel and increase the compressed air volume of raw materials;
6). Compared with PSA, it is not necessary to set up air and nitrogen buffer tanks. It is small in size and light in weight. It is the best choice for mobile nitrogen and oxygen enrichment equipment;
7). Nitrogen products have low dew point, and can reach -70ºC dew point under long-term continuous operation conditions;
8). The nitrogen product is clean without any dust and particles;
9). The startup and shutdown are convenient and quick, the operation is simple, and qualified nitrogen can be produced in a short time;
10). The equipment form can be designed according to the user's application requirements, which can be box type, skid-mounted type or container type;
11). The equipment does not have any special requirements for civil construction, and the installation cost is low;
12). There are no special requirements for the environment, and it can operate under harsh conditions.
