Store liquid in buckets or other open storage vessels. 

A platform was being constructed from one storage tank to another, without the workers knowing that mixture of benzoic acid and air in the open storage tank could explode. DSM is the largest European producer of benzoic acid which is used in a range of applications from a pla.sttcizcf to food preservative. DSM s capacity here is 440 million lb per year. 

A closed sorption system is shown in Figure 8. It is based on the same physical effect as the open storage. However the engineering is quiet different from open sorption systems. Closed system could be more precisely described as evacuated or air-free systems. The operation pressure of the fluid to be sorbed can be adjusted in theses systems. In closed systems components, which are not existing in the atmosphere, can be used, because there is no connection to the ambience. 

Evaporation of a solution of the picrate in the diether (b.p. 230°C) caused a violent explosion. The solvent had probably peroxidised dining open storage and the residual mixture of peroxide and picrate had exploded as evaporation proceeded. Use of peroxide-free solvent and lower (vacuum) evaporation temperature appeared to be safe. 

A slurry pump operating at 1 atm must be selected to transport a coal slurry from an open storage tank to a rotary drum filter, at a rate of 250 gpm. The slurry is 40% solids by volume and has an SG of 1.2. The level in the filter is 10 ft above that in the tank, and the line contains 400 ft of 3 in. sch 40 pipe, two gate valves, and six 90° elbows. A lab test shows that the slurry can be described as a Bingham plastic with v = 50 cP and t0 = 80dyn/cm2. 

Much unnecessary exposure to harmful materials arises from the accumulation of dust, other solids, and liquids around a workstation, as well as open containers of solvents and other chemicals stacked in open storage areas. Enforcement of cleanliness and tidiness can do much to reduce this unnecessary exposure. A regular cleanup schedule should be instituted along with immediate cleanup of spills, covering of open containers, and general tidy practices. Toxic wastes should not be allowed to accumulate. Arrangements should be made for their proper disposal. 

A liquid release offers the potential for the formation of an aerosol (mist). Aerosol formation is influenced by mechanical force (acceleration) and fluid properties, such as the material s surface tension. Additionally, in some systems the pressure, because of static head, may be adequate to cause some aerosol formation and must be considered. Examples of liquid releases include an accidentally opened storage tank drain valve, a pipeline failure downstream of a pump, a damaged nozzle at the base of a liquid knockout drum, or the failure of a loading hose. 

Oil-wet materials, sand, and clay, separated from either oil or water layers, are washed with the solvent or diluent until they are free of bitumen and the residual solvent is stripped from the mineral matter with steam. The mineral matter is clean and is sent to waste or used as fill without danger of spontaneous combustion, or it is used in cement manufacture. The aqueous phases condensed from such stripping and from the decanter of the azeotropic system has so little solvent, in hundredths of a percent, that it is neglected. It evaporates readily in open storage. This distilled water is used for any suitable purpose. 

Air is needed by the bacteria for their work . For acetic fermentation to start, the must has to be adequately aerated. Open storage alone is often not enough. 

Weigh 30 pmol (22.32 mg) DOPE, 20 pmol (9.47 mg) CHEMs and 2.5 pmol steric stabilizing polymer (17.02 mg (DDGG) (EO)jj or 7 mg PEG(2000)-DSPE). Always allow lipids to acquire room temperature before opening storage containers. 

On the other end of the scale of sophistication are agglomeration methods needed for low cost applications in the field of recovery of small amounts of valuable materials by leaching and waste processing for disposal. Many finely divided particulate wastes cannot be deposited in landfills or similar open storage facilities because of the danger of recontamination by wind and water. Because, in this case, agglomeration is only an additional cost, the cheapest possible method must be selected.

Solids such as bulk materials (open storage, covered storage, silos, bunkers) and piece goods (sack and drum storage, etc.). 

Epezite typically forms tiny popcornlike crystals. Portlandite crystallizes in pore spaces as tablets and platelets. The growth of epezite was thought to be responsible for clinker disintegration in open storage (even in supposedly tightly sealed containers on the... 

The rule does not establish opacity or limits for particulate matter from open storage piles (which include the equipment used in the loading, nnloading, and conveying operations at the facility) or roadways. However, the rule requires owners or operators of these facilities to develop and comply with a fugitive coal dust emissions control plan. This plan mnst require implanentation of one or more control measures to minimize fugitive emissions of coal dnst that are appropriate for the particular site. 

In fact, in some areas, local environmental regulations may rule out open storage, but it should be considered at least initially, because it can be less expensive from a total cost standpoint, even with environmental controls.
