Advantages of PSA nitrogen generators
Advantages of PSA nitrogen generators
High nitrogen purity
Adsorption PSA nitrogen generator plants allow production of high-purity nitrogen from air, which membrane systems are unable to provide – up to 99.9995% nitrogen. This nitrogen generator for coal mine purity may also be ensured by cryogen systems, but they are considerably more complex and justified only by large consumption volumes. Peak Scientific Inc. has a system which produces 99.9995% purity in a compact generator. The Nitrogen generator use CMS (Carbon Molecular Sieve) technology to produce a continuous supply of ultra high purity nitrogen and are available with internal compressors or without.
Low operating costs
By substitution of out-of-date air separation plants nitrogen production savings largely exceed 50%.
The net cost of nitrogen produced by VPSA oxygen generator is 20 to 30 times less than the cost of bottled or liquefied nitrogen.
Membrane Technology
Membrane PSA nitrogen generator
Gas separation concept
The operation of membrane systems is based on the principle of differential velocity with which various gas mixture components permeate membrane substance. The driving force in the gas separation process is the difference in partial pressures on different membrane sides.
Membrane cartridge
Flux distribution inside the fiber
Structurally, a hollow-fiber membrane represents a cylindrical cartridge functioning as a spool with specifically reeled polymer fibers. Gas flow is supplied under pressure into a bundle of membrane fibers. Due to the difference in partial pressures on the external and internal membrane surface gas flow separation is accomplished.
Advantages
Economic benefits
By substitution of out-of-date cryogenic or adsorption systems nitrogen production savings generally exceed 50%.
The net cost of nitrogen produced by nitrogen complexes is 20 to 30 times less than the cost of cylinder or liquefied nitrogen.
Module design
The advantage of modularity makes nitrogen generators especially beneficial for Company customers. Where necessary, the output capacity of a plant may be increased at the minimum cost. This option appears all the more useful where a project envisages a subsequent increase in enterprise capacity.
Dependability
Gas separation units have no moving component parts, thus ensuring the exceptional reliability of Company plants. Membranes are highly resistant to vibration and shocks, chemically inert to greases, moisture-insensitive, and capable of operating over a wide temperature range of –40°С to +60°С. With appropriate maintenance, membrane unit useful life ranges between 130,000 and 180,000 hours (15 to 20 years of continuous operation).
