A practical example for capacity utilization of a production train in a MP plant over a 12-month period is shown in Figure 5.6. For the sake of simplicity, only time-based and asset utilization, but not the product concentration, are considered. As shown in the graph, the plant runs flat-out for the first 10 months. Because an order has been canceled, there is no production at all during November and December. At first glance, this would result in a capacity utilization of n or 83% for the full year. However, the reality is quite different, and the actual record of plant performance during the year under review is as follows ... 

The situation where the excess electric charge in the bulk of the semiconductor is zero has a particular importance because this can often be obtained experimentally. This state is called flat band situation and the respective electrode potential, flat band potential because in the absence of electric fields inside the semiconductor the position of the band edge energies runs flat from the interior to the surface 20>. This energy pattern at the semiconductor-electrolyte contact is shown in Fig. 10 for the flat band situation, i. e. an anodic and a cathodic...

Some safe limits may have no meaningful value. For example, if a pressure vessel is designed for full vacuum operation, then that vessel has no safe lower limit for pressure. Similarly, in Table 1.5, no value for a safe upper limit for high flow is provided because the system is safe even when the pumps are running flat-out with all control valves wide open. 

Some process designers start out saying they do not require any turndown because the process is so designed that it can always run flat out at 100% of design rate. As they start to get the kinks out of their system, and realize that neither they nor those who will run it are perfect, the designers will want a high-turndown ratio that would be beyond reason, costwise. Table 6.4 gives approximate turndown ratios possible with a variety of turndown control systems. 

As for viscose fibres, these are mostly produced as staple fibres for textile and nonwoven applications. In 2011, world production was 3.246 million tons [49] while filament yam for textile and technical applications reached 332 000 tons in 2011 [49] with a share of technical yarns of 56 000 tons. Technical viscose fibres, also called rayon or viscose rayon, are used mainly as carcass reinforcing fibres in fast-running and run-flat tyres. Lyocell fibres are produced only as staple and virtually exclusively by Lenzing AG, Austria, with a production capacity of 140 000 tons in 2011 [50]. 

These companies irrvesting in Chinese chemical capacity will have a significant advantage over companies importing into the region and will be able to displace imports, mearring that new plants shottld run flat-out soon after startup. A good example is polyrrrethanes and polycarbonate where domestic capacity is virtrrally non-existent. Indnstry experts see no reason that this shonld... 

Straight-running flat-top chains are standardized in ASME B29.17M, Hinge Type Flat Top Conveyor Chains and Sprocket Teeth. 

ASME standard B29.17 covers only three basic models of straight-running flat-top chain. A basic steel chain, a normal-duty plastic chain, and a heavy-dnty plastic chain. The standard fists limiting dimensions that ensure the chains are interchangeable. The standard requires that the standard chain from one manufacturer will run on the standard sprockets from another manufacturer, and that a standard chain from one manufacturer will interconnect with the standard chain from another manufacturer. The pitch of all the standard chains is IV2 inches. The standard steel chains may be made of either corrosion-resistant or carbon steel. Top-plate width is not covered by the standard. The designer must consult manufacturers catalogs for such information. 

Standard flat-top chains are exclusively intended for use on conveyors. They are widely used in straight-running flat-top conveyors in the beverage bottling and canning, food processing, and product packaging industries.

Using such cooling, tubes can be run at levels of up to 40 mA beam current at around 40 kV. Running flat out, the average source should last at least 2000 h before the filament burns out. Most X-ray sources of the type described above are made as a sealed glass X-ray tube to be fitted onto the manufacturers high voltage supply units. These tubes are discarded once the filament is burned out. Alternatively, sources are available where the filaments are replaceable, and hence the X-ray chamber must be continuously evacuated.
