Packing, storage and transportation

After passivation, the surface of the prereduced catalyst is covered with a layer of oxide film, which cuts off the internal active a-Fe from the air. The prereduced catalyst after passivation will still slowly react with oxygen in the air at room temperature. During transportation, the oxide film will flake off locally as the result of particle collisions and friction, while they can be reoxidized in air to form a new oxide film. 

The catalyst should be stored in the dry storeroom. Prereduced catalyst cannot be contacted with water, because water molecules will go through the oxide film and react with the active a-Fe, and release H2 as in the reaction, Fe + H20 = Fe0 + H2.

Thermal explosions have been discussed in various books and review articles (for example, [7], [28] [31]). The presentations in [28] and [30] are especially extensive. These explosions have been studied for both gaseous and condensed-phase reactants. In addition to being of fundamental interest to chemical kinetics, they are of practical concern in wide-ranging problems of fire and explosion safety for example, a hazard in storage and transportation of crystalline NH4NO3, used in fertilizers, is the possible occurrence of a thermal explosion if suitable packing precautions are not applied. 

The boiling point is an important characteristic of a war gas, not only because of its connection with vapour tension and therefore with the tactical aims attainable in warfare, but also because of its influence on the ease of storage and transport of the substance. A war gas whose boiling point is lower than ordinary temperatures, as, for example, phosgene, is difficult to pack and necessitates the use of refrigerating apparatus during transport in order to keep it below its boiling point. 

Products packed into PIF should be stored in ventilated storage facilities at temperatures of 10—40°C. Direct sunlight is inadmissible. Continuitj of the package should be observed during storage and transportation. 

Storage and Transportation. Amino resins should be stored in stainless steel or in lined carbon steel containers. The lining should be resistant to degradation or swelling by alcohols. Unlined steel vessels can be used under certain circumstances. The unlined vessel should have a desiccator on the gas-inlet line to remove water vapor from the gas that is used to replace the resin as it is pumped out of the tank. Methylated amino resins are preferably stored in lined drums or in fiber pack containers. 

Dangerous Goods refers to dangerous substances that are properly packed and labeled for storage and transport by road, rail, sea, or air (Eigure 24.1).

Production and Shipment. Estimated adiponitrile production capacities in the U.S. in 1992 were about 625 thousand metric tons and worldwide capacity was in excess of lO metric tons. The DOT/IMO classification for adiponitrile is class 6.1 hazard, UN No. 2205. It requires a POISON label on all containers and is in packing group III. Approved materials of constmction for shipping, storage, and associated transportation equipment are carbon steel and type 316 stainless steel. Either centrifugal or positive displacement pumps may be used. Carbon dioxide or chemical-foam fire extinguishers should be used. There are no specifications for commercial adiponitrile. The typical composition is 99.5 wt % adiponitrile. Impurities that may be present depend on the method of manufacture, and thus, vary depending on the source. 

Adsorption of supercritical gases takes place predominantly in pores which are less than four or five molecular diameters in width. As the pore width increases, the forces responsible for the adsorption process decrease rapidly such that the equilibrium adsorption diminishes to that of a plane surface. Thus, any pores with widths greater than 2 nm (meso- and macropores) are not useful for enhancement of methane storage, but may be necessary for transport into and out of the adsorbent micropores. To maximize adsorption storage of methane, it is necessary to maximize the fractional volume of the micropores (<2 nm pore wall separation) per unit volume of adsorbent. Macropore volume and void volume in a storage system (adsorbent packed storage vessel) should be minimized [18, 19].
