Hazardous Wastes Hazardous Wastes for deliveiy to a treatment or disposal facility normally are collected by the waste producer or a licensed, speciahzed hauler. Typically, the loading of collection vehicles is completed in one of two ways (1) wastes stored in large-capacity tanks are either drained or pumped into collection vehicles, and (2) wastes stored in sealed drums or other sealed containers are loaded by hand or by mechanical equipment onto flatbed trucks. To avoid accidents and possible loss of life, two collectors shoiild always be assigned when hazardous wastes are to be collected.

A credible spill for Catastrophic Loss Potential. For a catastrophic loss potential, the spill size should be based on the contents of vessels or connected vessel train. The existence of shutoff valves between vessels should not be considered. In addition, the catastrophic failure of major storage tanks should be considered. Leaks in pipelines carrying materials of concern from large-capacity, off-site, remote storage facilities must be considered. For this purpose, it must be assumed that the pipeline is completely severed and that the spill will run for 30 minutes. 

Although the first industrial application of anodic protection was as recent as 1954, it is now widely used, particularly in the USA and USSR. This has been made possible by the recent development of equipment capable of the control of precise potentials at high current outputs. It has been applied to protect mild-steel vessels containing sulphuric acid as large as 49 m in diameter and 15 m high, and commercial equipment is available for use with tanks of capacities from 38 000 to 7 600000 litre . A properly designed anodic-protection system has been shown to be both effective and economically viable, but care must be taken to avoid power failure or the formation of local active-passive cells which lead to the breakdown of passivity and intense corrosion. 

In this process, the soil is mixed with water to obtain a pumpable slurry that is fed to a large-capacity continuously stirred tank reactor. The reactor is then supplemented with oxygen, nutrients, and, when necessary, a specific inocula of microorganisms to enhance the biodegradation process. 

Table XVI shows two experiments which compared the same wine stored under different conditions (46). In both cases, the wine richer in anthocyanins is also that which is less colored. The mediation of tannins is not enough to explain the differences in color these can only be explained by a different structuring of the anthocyanin molecules. More specifically, the anthocyanin molecules will be reduced to colorless flavenes (14) during fermentation, which is a reductive process. The reoxidation occurs more rapidly in wooden casks which allow better oxygen penetration than metal storage tanks or large capacity casks. However, the flavenes themselves are relatively instable and can be irreversibly hydrolyzed into dihydrochalcones (16). This explains the lack of relationship between anthocyanin concentration and color, independent, of course, of the eventual appearance of free sulfur dioxide.

The range of culture flasks and reactor types employed is quite wide, both for suspension and adherent cultures, from small Carrel s or Roux s flasks to roller bottles. Fixed- and fluidized-bed bioreactors, air-lift reactors and even stirred and aerated tanks with capacities up to 15 m3 are common in large plants producing monoclonal antibodies (mAbs) for anticancer therapies (Adams and Weiner, 2005 Griffiths, 1988). 

Treatment can also be carried out using a continuous or semicontinuous operation. In each case, accurate, in-line pH measurement is needed to control the addition of the treatment chemicals. Filtration can be accomplished on a semicontinuous basis using plate and frame hlters by sizing the treatment tanks to allow surge capacity for hlter cleanout intervals, or a continuous vacuum drum hlter can be used. These processes lend themselves to the large capacity plants. 

Crude oil is generally stored in large tanks with capacities up to a few thousand tonnes depending upon the size of the refinery. These tanks have optional heating coils but most of them do not have mechanical agitation. Agitation is beneficial because wax, phospholipids, and moisture tend to settle to the bottom of the tank and this may cause increased refining losses. Crude sunflower oil specifications... 

The spectrum of hydrogen quantities that might be released into the atmosphere varies from small amounts in a vehicle tank to the large capacity of a stationary storage tank. Table 8-7 lists typical LH2 quantities together with the corresponding volumes of a (stoichiometric) mixture gas cloud and the (theoretical) TNT equivalent. 

Cargo tanks are large-capacity cryogenic storage tanks either mounted on a truck body or forming a semitrailer body. The maximum capacity of these units is 11,300 U.S. gal although the most common size used to ship liquefied industrial gas products over the road is 7000 U.S. gal [2]. The truck has a high pressure liquid transfer pump on board which can fill a... 

The low-temperature storage tanks are best suited for the storage of ammonia from the synthesis loop at a low temperature and for the shipping terminals handling a large capacity. The tanks operate at atmospheric pressure, and they are well insulated to minimize the... 

The containment basin and walls should be constructed of concrete and be large enough to contain the tank s entire contents. If a basin serves more than one tank, its capacity must be sufficient to contain 110% of the largest tank plus the maximum rainfall in a 24-h period. Most plasticizers do not require heated... 

The 4th and 5 th Marine Divisions emphasized the greater eflfective-ness of the main armament type as opposed to the auxiliary flame thrower, of which the 4th Division had twenty-four. These divisions recommended more large capacity flame throwers and their incorporation as organic equipment in ail tank battalions. Although the 3d Marine Division entered the Iwo Jima operation without main armament flame throwers, it was later on able to borrow some from the other divisions. In its opinion this type was better against enemy defenses than the auxiliary bow gun flame throwers with their shorter range and limited traverse. ... 

The XXIV Corps reported that the main armament flame tank was one of the most effective weapons used on Okinawa and that the Japanese fear of flame was greatly exploited by the flame tanks. The 7th Infantry Division spoke of the outstanding success of the flame tanks. The periscope mounted flame thrower found little use in the fighting on Okinawa as the large-capacity flame tanks were available. 

A fire bomb was simply a large capacity container filled in the field with napalm gel. It began as a field improvisation. Fighter planes carried jettisonable fuel tanks for long missions, and it became customary for the pilots, on the trip homeward, to drop these tanks on targets... 

Cargo tank capacities range up to 17 000 gal (64 m ). Although no minimum capacity is given for them in the specifications, cargo tanks are normally large capacity tanks permanently mounted on truck bodies, or they form a semitrailer body. In some instances, truck tractors draw double tank trailers containing compressed gas.
