Easy Operate Poly Propylene Vocs Membrane Separator For Automobile Industry
When two or more mixed gases pass through a polymer membrane, the relative permeation rates of different gases in the membrane are different due to the difference in solubility and diffusion coefficient of different gases in the membrane. According to this characteristic, under the action of the pressure difference on both sides of the membrane, gases with relatively fast permeation rates such as water, oxygen, carbon dioxide, etc. permeate through the membrane and are enriched on the permeate side of the membrane, while gases with relatively slow permeation rates Gases such as nitrogen, carbon monoxide, argon, etc. are enriched on the stagnation side, so as to achieve the purpose of mixed gas separation. When the pressurized purified air is used as the gas source, inert gases such as nitrogen are enriched into high-purity nitrogen-rich gas, and oxygen-enriched air is evacuated from the permeation side. Compared with the low temperature method and the pressure swing adsorption method, the membrane nitrogen enrichment technology has the advantages of simple operation and continuous and stable work.
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.
