PSA Nitrogen Generator

BROTIE PSA Nitrogen Generator

(BR-A, B, C, D, E, F series with purity 95%, 99%, 99.5%, 99.9%, 99.99%, 99.999%)

Principles:
PSA nitrogen generator uses carbon molecular sieve as sorbent, produces nitrogen by making use of the PSA principle. Under certain pressure, carbon molecular sieve has different oxygen/nitrogen adsorption capacity, i.e. much more oxygen adsorption capacity than nitrogen adsorption capacity. PLC controls pneumatic valve on/off to realize two towers alternate adsorption and desorption as per pressure change, carries out oxygen/nitrogen separation and produces nitrogen with desired purity.
BROTIE nitrogen generation system incorporates one air compressor, one refrigerant air dryer and filters, main nitrogen generator, air buffer tank and nitrogen buffer tank. With higher nitrogen pressure required, one BROTIE totally oil-free nitrogen compressor will be equipped after the nitrogen generator to increase the nitrogen pressure to required pressure.
Compressed air is purified through the air dryer and filters to a certain level for main generator to work with. Air buffer is incorporated for smooth supply of compressed air thus to reduce fluctuation of work demand for air compressor. The generator produces nitrogen with PSA (pressure swing adsorption) technology, which is a time proven nitrogen generation method. Nitrogen with a desired purity is delivered to nitrogen buffer tank for smooth supply of product gas. Nitrogen in buffer tank is maintained at 6barg pressure. After BROTIE totally oil-free nitrogen compressor, the pressure will be compressed to required pressure. It is adjustable for you to adjust the outlet pressure by a pressure regulator valve, so that it can be used for your specific use.

Applications:
1. Metallurgy: For anneal protection, agglomeration protection, nitrogen furnace washing and blowing ,etc. Used in fields such as metal heating treatment, powder metallurgy, magnetic material, copper process, metallic mesh, galvanized wire, semiconductor, etc.
2. Chemical and new material industries: For chemical material gas, pipeline blowing, gas replacement, gas protection, product transport, etc. Used in fields such as chemical ,urethane elastic fiber, rubber, plastic, tire, polyurethane, biological technology, intermediate, etc.
3. Electronic industry: For encapsulation, agglomeration, anneal, deoxidization, storage of electronic products. Used in fields such as peak welding, circumfluence welding, crystal, piezoelectricity, electronic porcelain, electronic copper tape, battery, electronic alloy material, etc.
4. Food and Pharmacy: nitrogen generator provides a clean nitrogen blanket to food products such as edible oil, wine, juice, milk powder and so on. It prevents the growth of bacteria and preserves better freshness with fermentation control and odor suppress. Now nitrogen packaging is a trend for food industry to prevent food products spoilage, preserve freshness, maintain flavor and extends shelf life.
5, Heat Treatment: nitrogen inert and protection for the parts under high temperature is very important to prevent them from oxidization and to improve surface quality. BROTIE nitrogen generation systems have been applied as inert atmospheres to various processed in heat treatment such as converting process sealing, blast furnace top sealing, coal powder blowing, continuous casting, continuous rolling, stress remove, aging, annealing, carburizing,, quenching etc. They are also used as protecting gas for welding and powder metallurgy, purge gas and diluting gas also.
One-step PSA technology for high purity nitrogen generation or hydrogen purification using ammonia cracker or other hydrogen source as a low-cost alternative.

Optional:
1, BRO-CONTROL system, SMC online digital flow meter and a SMC pressure sensor and a Siemens touch-screen are added. Touch-screen BRO-CONTROL control, display and alarm system makes all the generation system to be operated by one touch. BRO-CONTROL displays working parameters, reminds filter elements replacing and instructs trouble shooting. It enables remote control. BRO-CONTROL system can show three optional languages as Chinese, English and Russian.
