Product Description

SEPARATING WITH FIBERS

The aerospace, energy, chemical, and food industries-all of these sectors require nitrogen at different levels of purity. With its newly developed hollow-fiber membrane, Keepwin is offering a needs-oriented, efficient, and energy-saving solution for obtaining the desired gas.

Incombustible, inert , odorless, and tasteless-these properties make nitrogen a highly needed gas for a number of branches of industry. It is obtained from air, which has a nitrogen content of up to 78 percent. Air is also made of up to 21 percent oxygen-an extremely reactive gas that facilitates fires. Gas separation processes are designed to separate oxygen and nitrogen.

Cryogenic air separation, also known as the "Linde process," is particularly good at doing this. It can extract nitrogen at a purity of over 99.99 percent. But this level of quality comes at a price: Cryogenic air separation consumes a lot of energy and is only profitable in large-scale production. For many applications, though, technical nitrogen with a purity of 95 to 98 percent is sufficient.

One of the main applications for the inert gas of such qualities is active fire protection. In server rooms, for example, a supply of N2 ensures that the oxygen content in the indoor air drops below 16 percent. At this level, flames either die immediately or never form in the first place. The chemical industry frequently uses nitrogen for explosion protection in production plants or tank farms. For these purposes, nitrogen can be obtained far more cost-effectively with membrane technology.

Advantages:                                                    Fields of application:
• Very high selectivity                                          • Nitrogen generation
• Low energy consumption                                   • Hydrogen upgrading
• Separation at room temperature                          • Helium recovery
• Low space requirements                                    • Extraction of Methane
• Continuous separation process
• Simple modular setup
• Flexible and easily expanded
• No other auxiliary materials, such
as water and sorbents, required
• No emissions into the environment

How a Nitrogen Generator Membrane Works

Pressurized air is fed to one end of the hollow fiber membranes. Membranes contain a bundle of hollow fibers with holes small enough to allow the smaller oxygen molecules to exit through them under pressure. The permeation rates of water vapor, CO2, and oxygen contained in the air stream are faster than nitrogen and argon and will rapidly diffuse through the fiber walls. The slower diffused nitrogen molecules remain in the fiber bore and are collected as the nitrogen product gas. The air flow rate will determine how much undiffused oxygen remains with the nitrogen gas. The nitrogen product gas is extremely dry, with atmospheric dew points typically below -40°F. The membranes act like a filter with no moving parts and continuously generate nitrogen at selected flow and purity.

Safety Features
1.Equipped with temperature control system: to ensure that the temperature of the compressed air entering the membrane system is constant. When the temperature exceeds the set value, the heater can be automatically cut off to protect the membrane module. Membrane insulation sleeve heating adopts PTC with tropical automatic temperature limiting, protective film group.
2. Equipped with an inlet and outlet pressure interlock switch: When compressed air entering the membrane system is interrupted or the air pressure is lower than a certain set value, the heater can be automatically turned off to protect the membrane group and the heater.
3.Nitrogen purity control system: The oxygen analyzer can ensure the accurate display of the nitrogen content of the product, ensure the system is safe and reliable, and the nitrogen purity of the product can be continuously adjusted between 90% -99%. The nitrogen produced by this equipment can reach the qualified purity within 5 minutes after startup. It is equipped with an automatic vent valve. When the purity of the product gas exceeds the set value, the unqualified nitrogen is automatically discharged to the atmosphere immediately, ensuring the user's requirements. Nitrogen is not contaminated.
4.The safety relief valve can protect the pressure vessel from overpressure.
5.All pressure vessels, high-pressure pipe fittings and valves shall be provided with the certification of pressure vessel management department.
