A relatively small pressure can result in a very large force if it is applied over a large area. Inadequately vented atmospheric storage tanks may therefore rupture if, for some reason, e.g. a high inflow, they are subjected to a relatively low internal pressure. Large side-on structures, windows, etc. are particularly prone to damage from an explosion even at a significant distance from the epicentre. [Pg.56]

The design and construction of atmospheric storage tanks for the petroleum industry are covered by British Standard BS 2654, and the American Petroleum Industry standards API 650 (2003) and 620 (2002). The design of storage tanks is covered in the books by Myers (1997), and Jawad and Farr (1989). See also the papers by Debham et al. (1968) and Zick and McGarth (1968). [Pg.879]

Once VOC emissions have been eliminated or reduced at source, then recovery of the VOC for reuse should be considered. Figure 25.6 shows a vapor recovery system associated with an atmospheric storage tank. The storage tank is fitted with a vacuum-pressure relief valve, which... [Pg.556]

The order of process items in the layout spacing recommendations (Table 19) is quite similar. The flares are on the top of the list. The next unsafe are cooling towers, boilers and compressors. Storage tanks under pressure appear next. After that come low pressure and atmospheric storage tanks and pumps of flammable liquids. The last and safest group is formed of equipment handling nonflammable and nontoxic materials. [Pg.85]

Atmospheric storage tanks of flammable liquids and pumps of flammable or toxic liquids are located in the equipment safety group 1, since they are sources of flammable liquid which do not produce a vapour cloud directly. [Pg.86]

Lightning is generally considered a form of static electricity that is being discharged from particles in the atmosphere. Many instances of lightning induced hydrocarbon fires have been recorded, especially at atmospheric storage tanks. [Pg.150]

Atmospheric storage tanks are normally fitted with pressure-vacuum relief valves to reduce vapor emission and evaporation losses to atmosphere. [Pg.155]

In general, atmospheric storage tanks are limited to a maximum operating pressure of 0.5 psig (3.5 kPa) with the exception that those designed and constructed according to API Standard 650, Appendix F are permitted to operate up to 1.0 psig (6.9 kPa) (NFPA 30, 2000). [Pg.285]

Propane can be stored as liquid in pressurized (approximately 15 atmospheres) storage tanks and/or at cold temperatures and vaporizes to a gas at atmospheric pressure and normal temperatures. This makes it possible to store a large volume of propane as a liquid in a relatively small volume propane as a vapor occupies 270 times the volume of propane in liquid form. This makes liquid propane an ideal fuel for transport and storage until needed. [Pg.231]

Corrosion in atmospheric storage tanks can be divided into three zones the tank roof, the walls, and the bottom. Corrosion on the underside of the tank roof is controlled by the relative amount of air and... [Pg.107]
