Product information
Nitrogen production through membrane separation benefits from the development of the chemical industry and the continuous emergence of new materials. It began to be commercialized in the 1880s. XINRAN membrane in the United States is the first nitrogen membrane product put into commercial operation in the world. The core of membrane separation is the physical process of achieving gas separation by utilizing the different diffusion coefficients of different components in air in the membrane fiber wall (polymer material). Polymer materials are made into hollow fiber membrane filaments as thick as human hair. When gas passes through the hollow interior of the membrane fiber filaments, the permeation rates of different components of gases on the fiber wall are different, resulting in different permeation amounts. Through a certain length of membrane fibers, nitrogen with the required purity is obtained (90 - 99.99%). The discharged oxygen-rich gas seeps out from the side walls of the membrane fibers, and the oxygen-rich concentration can reach about 40%.
Scope of application The large-scale membrane separation nitrogen production equipment provided by Xinran is mainly aimed at the use of large-flow nitrogen in petroleum, chemical, refining, steelmaking, * and other industries. According to customers 'actual needs (different flow rates, nitrogen purity, nitrogen pressure, nitrogen pressure dew point, etc.), it uses American XINRAN membrane separation technology and decades of complete set experience to provide customers with professionally customized equipment. Xinran membrane nitrogen production equipment is characterized by the new technology of air separation at room temperature, low noise, meeting environmental protection requirements, no moving parts, less equipment maintenance, high reliability in continuous operation, long equipment service life, and simple capacity expansion for more than 15 years. It only needs to be added in parallel. Adding membrane parts and increasing the amount of raw material compressed air can be compared with PSA nitrogen production. It does not require large air and nitrogen buffer tanks, is small in size and light in weight. It is the best choice for mobile nitrogen production equipment. Nitrogen products have low dew point and can reach-60 ° C. Nitrogen products are clean. Low dust and low particle pollution are convenient and quick to start and stop. The operation is simple. It can produce qualified nitrogen internally in a short time. Equipment forms can be based on user application conditions. There are box, skid-mounted, and container types that have no special requirements for civil engineering. The installation cost is low and no special requirements for the environment. They can operate under harsh working conditions.
