PRESSURE-SWING ADSORPTION SYSTEM AND METHOD FOR NBC COLLECTIVE PROTECTION

Abstract

A pressure-swing adsorber using type 13X (10 Angstrom) molecular sieve is used in lieu of or ahead of an activated or impregnated carbon filter in an NBC collective protection system. The pressure-swing adsorber removes a much wider range of toxic vapors from air than an impregnated carbon bed, is fully regenerable, and has a long service life. In one system for supplying purified air to a shelter, air is compressed by a gas turbine-driven compressor, fed through an aerosol removal system, purified by an industrial-type pressure-swing adsorber using type 13X molecular sieve, filtered by a Super HEPA filter, and expanded to atmospheric pressure in a turbo-generator. In another system for field medical oxygen generation, a compressor is driven by an electrical motor and the purified air is fed to a pressure-swing oxygen concentrator using type 5A molecular sieve.
