Liquified gases are sometimes stored in well-insulated spherical containers that are vented to the atmosphere. Examples in the industry are the storage of liquid oxygen and liquid ammonia in spheres. If the radii of the inner and outer walls are r, and r, and the temperatures at these sections are T, and T, an expression for the steady-state heat loss from the walls of the container may be obtained. A key assumption is that the thermal conductivity of the insulation varies linearly with the temperature according to the relation ...

Vertical cylindrical tanks, with flat bases and conical roofs, are universally used for the bulk storage of liquids at atmospheric pressure. Tank sizes vary from a few hundred gallons (tens of cubic metres) to several thousand gallons (several hundred cubic metres). 

Storage of liquid hydrogen is achieved in large well-insulated tanks from which it is dispensed to liquid tankers for transport over the road. The use of hydrogen sensors (mostly flammable sensors) in and around such facilities is a common safety practice today. As hydrogen-specific sensors and solid-state sensors become more reliable, and if their cost is reduced they will replace the more common flammable gas sensors.

A number of reasons have been outlined, both environmental and economic, of why the transport and storage of liquid chlorine are not desirable. Combining the chlor-alkali plant with the EDC unit, as suggested, makes EDC the intermediate material in the vinyl chain. By looking at the physical properties of the two materials, shown in Table 21.4, additional reasons become apparent favouring EDC as the much preferred material for storage and transport. (As an additional comparison, the properties of VCM are provided as well.)...

The long lifetimes of geotextiles are shared with a parallel application of plastics underground as impermeable linings to seal canals, reservoirs, tunnels, and, most critical of all, the storage of liquid waste. Generally made from HDPE or PVC, these polymer... 

One major advantage of DME use is that it can be stored as a high-density liquid phase at modest pressures (around 5 atm) and delivered as a gas-phase fuel in a pumpless operation. Therefore, the use of DME can potentially combine the advantages of easy fuel delivery of pressurized hydrogen and the high energy density storage of liquid fuel. In addition, DME is less toxic than methanol. 

Commercial surfactants are, in general, chemically impure and may contain varying amounts of water and additives. After prolonged storage of liquid nonionic surfactants the composition tend to change. It should be observed that even trace impurities might sometimes produce a bottleneck in carrying out spectroscopic studies of proteins/nucleic acids in RMs. In addition, the impurities may interfere with the behavior of biomolecules and also cause problems of reproducibility. To achieve reproducible results, it is advisable to purify the surfactants to be used whenever possible [121.

The long-term storage of liquids and gases is best accomplished in an ampule or bulb fitted with a break-seal. Once the sample is sealed off in such a container, leakage is no problem as it would be if a stopcock or valve were used. Furthermore, this practice is economically sound, since a break-seal is much less expensive than a stopcock or valve.
