Commercially pure (< 99.997%) helium is shipped directiy from helium-purification plants located near the natural-gas supply to bulk users and secondary distribution points throughout the world. Commercially pure argon is produced at many large air-separation plants and is transported to bulk users up to several hundred kilometers away by tmck, by railcar, and occasionally by dedicated gas pipeline (see Pipelines). Normally, only cmde grades of neon, krypton, and xenon are produced at air-separation plants. These are shipped to a central purification faciUty from which the pure materials, as well as smaller quantities and special grades of helium and argon, are then distributed. Radon is not distributed commercially. 

Alkoxides should be stored under cool, dry conditions. The soHds are packed in polyethylene bags under nitrogen or argon that are shipped in dmms with foam mbber gaskets. For the Hquid alkoxides steel dmms are used, usually with a polyethylene liner.

Figure 4.2 For storage and shipping, SPMDs (shown on a deployment apparatus rack) are placed in a clean metal can, flushed with argon, and sealed with a gas tight lid. This figure reproduced courtesy of the American Petroleum Institute (Huckins et al., 2002).

The synthetic route followed in the encapsulation of [Ru(bpy)3] + in ZeoliteY is referred as ship-in-a-bottle synthesis due to non-extractability of the [Ru(bpy)3] complex, once encapsulation has taken place within the cages of the zeolite Y. Nanoparticles of TiO was then introduced through TiClj in ethylene glycol mixture under argon, with sintering at 200°C. A schematic diagram of the synthesis is shown in Fig. 16.1 [1].

Argon is most economically shipped as a liquid. Liquid argon commonly is transported in liquid cylinders, cryogenic trailers, and portable tanks. Argon can be shipped in high-pressure gas cylinders and high-pressure cylinder trailers. 

DISPOSAL AND STORAGE METHODS absorb in dry earth, sand or vermiculite and place in a secured sanitary landfill store in a cool, dry location with adequate ventilation isolate from air, moisture, halogens, alkali metals, aluminum and rust outside storage is preferred normally refrigerated usually shipped in pressurized cylinders diluted with hydrogen, argon, nitrogen, or helium.

Argon is an inert, nontoxic, colorless, odorless gas that can act as a simple asphyxiant if it displaces the air needed to support life. It is normally shipped as a gas but is also available commercially as a liquid. The gas is heavier than air (sp. gr. = 1.38) and tends to flow into low-lying areas.

Argon gas is authorized for shipment in cylinders, tube tank cars, and tube trailers. Liquid argon is shipped as a cryogenic fluid in vacuum-insulated cylinders, insulated portable tanks, insulated tank trucks, and tank cars. 

Cylinders that comply with TC/DOT specifications 3 A and 3AA are the types usually used to ship gaseous argon, but it is authorized for shipment in any cylinders approved for nonliq-uefied compressed gas. These include cylinders meeting specifications 3A, 3AA, 3AX, 3AAX, 3B, 3E, 3T, 3AL, 39, 4B, 4BA, and 4BW in addition, continued use of cylinders complying with specifications 3C, 3D, 4, 4A, 4C, 3, 25, 26,... 

Gaseous argon is shipped in tube trailers with capacities ranging to more than 40 000 ft (l 130 m ). These trailers are built to comply with DOT cylinder specifications 3A, 3AA, 3AX, 3AAX, or 3T. 

Liquid argon is shipped in bulk at pressures below 25.3 psig (174 kPa) in special insulated tank trailers with capacities in excess of 400 000ft (ll 300 m ). 

Liquid argon is shipped and stored in small portable containers (dewar flasks), which hold quantities ranging from 1 gal to 25 gal (4 L to 95 L) or more. These containers are encased in shells and are heavily insulated they maintain the liquid at atmospheric pressure.
