A fluid storage and dispensing apparatus including a fluid storage and dispensing vessel having a rectangular parallelepiped shape, and an integrated gas cabinet assembly including such fluid storage and dispensing apparatus and/or a point-of-use ventilation gas scrubber in the vented gas cabinet. By the use of physical adsorbent and chemical sorbent media, the gas cabinet can be enhanced in safety of operation, e.g., where the process gas supplied from the gas cabinet is of a toxic or otherwise hazardous character.

Rectangular parallelepiped fluid storage and dispensing vessel

A carbon adsorbent adapted for adsorptive storage and subsequent desorptive release of a decomposition-susceptible gas is described. Such carbon adsorbent comprises porosity in which mesopore volume is less than 0.25 cm/gm of carbon adsorbent, in which the porosity comprises at least 80% by volume micropores, and at least 65% by volume of the micropores have pore diameter in a range of from 0.3 to 0.72 nm. The carbon adsorbent has a nitrogen adsorption BET surface area greater than 800 m/g of carbon adsorbent, measured at 77&#xb0; K, and a bulk density that is greater than 0.55 g/cc of carbon adsorbent. The carbon adsorbent can be utilized in gas storage and dispensing packages of varying type, to provide a safe and reliable source of decomposition-susceptible gas, e.g., acetylene for applications such as gas welding/cutting applications, atomic absorption spectroscopy applications, chemical synthesis and microelectronic products manufacturing.

Gas storage and dispensing system with monolithic carbon adsorbent

A system and method for recovering high value gas from a process stream, material or environment containing same, e.g., xenon by contacting gas from the process stream, material or environment with a carbon adsorbent effective to sorptively capture same, free of or with reduced concentration of fluid species present with the high value gas in the high value gas-containing gas in the process stream, material or environment. Other aspects of the disclosure include a radon detection method and product.

A particulate form carbon pyrolyzate adsorbent, having the following characteristics: (a) COcapacity greater than 105 cc/gram at one bar pressure and temperature of 273&#xb0; Kelvin; (b) COWorking Capacity greater than 7.0 weight percent; (c) COheats of adsorption and desorption each of which is in a range of from 10 to 50 kJ/mole; and (d) a CO/NHenry's Law Separation Factor greater than 5. The carbon pyrolyzate material can be formed from a polyvinylidene chloride-based polymer or copolymer, or other suitable resin material, to provide an adsorbent that is useful for carbon dioxide capture applications, e.g., in treatment of flue gases from coal-fired power generation plants.
