In 1990, worldwide capacities and production figures in metric tons were Western Europe capacity 266,000, production 180,000 Japan capacity 90,000, production 64,000 and United States capacity 145,000, production 88,600 (23).

As the Fermi level of the electrode approaches the surface state level of high state density, the surface state is charged or discharged as a capacitor. For convenience sake, we express the sum of a. and in Eqn. 5-86 as the surface state charge Qu and the capacity due to the surface state charge as the surface state capacity C.. Then, the interfadal capadty C is represented by the capadly of an equivalent drcuit shown in Fig. 5-60. 

The surface state capacity, Ch, is apparently zero in the range of potential where the Fermi level is located away from the surface state level (the state of band edge level pinning). As the Fermi level is pinned at the surface state, the capacity Ch increases to its maximum which is equivalent to the capacity Ch of the compact layer, because the surface state charging is equivalent to the compact layer charging in the state of Fermi level pinning.

United States capacity for fermentation industrial ethanol is estimated at 80 - 90 million gallons per year but this could be increased by diversion of distilled beverage production. 

The surface state capacitance Css is different from the space charge layer capacitance Csc and the Helmholtz layer capacitance Ch in that there is in general no distance associated with the surface state capacity. 

Since the distance between the Fermi level E and the energy bands varies with (see Section 5.3) f is also changed. If Fp = Ft, the surface state is half-occupied (f = 0.5), as shown in Fig. 5.8. Since the charge depends on the potential across the space charge layer, a differential surface state capacity can be defined by...

What is a typical extraction/processing plant like in terms of scale This is hard to quantify without picking what might be a typical example, but it is worth citing the NATECO2 production facilities in Wolnzach, Germany as an example of a technically sophisticated and diverse operation. Some of its stated capacity and capabilities are as follows ... 

Mill capacity within the United States is estimated at 19.0 million pounds of vanadium for 1973 through 1980. The United States capacity is well in excess of the 1973 demand for 12.5 million pounds for the United States and Canada and is adequate to satisfy the projected demand of 16.1 million pounds in 1980. Furthermore, a new producer has announced plans to produce vanadium oxide in the United States, bringing the total production capacity to 21.1 million pounds of vanadium by 1976. In addition to the basic United States V205 production capability, a major domestic converter is now producing millions of pounds of ferrovanadiiam per year from duty free steel slags imported from South Africa, a source, that if further developed, could satisfy the entire projected domestic demand for vanadium.

Simply stated, capacity varies. Rainfall, snowpack, seasons, drought, or unusually wet periods influence capacity. So do earthquakes, evaporation, seepage, increased usage, and higher population densities. No water source is exempt from the effects of some of these conditions. Minor fluctuations are of no concern. The variance in the readings one will obtain from any one source over a period of... 

We now introduce the concept of a block. A block is either of type serial or parallel comprising sub-blocks. A sub-block is either a component, or another block. Thus we generally have a block structure. If a block is of serial type the state (capacity) of the block is the minimum of the sub-block states. If the block is of parallel type the state of the block is the sum of the sub-block states. Note that there may be a maximum capacity of each block. 

Using the building blocks shown in Table 12.1, resin producers may prepare unsaturated polyester formulations to meet a broad spectrum of critical end-use requirements.The estimated 1979 consumption of unsaturated polyester resins in the United States by end-use areas (percentage by weight) is shown in Fig. 12-1. The fortunes of unsaturated polyesters production and consumption closely follow the gross national product of the United States, with a correlation coefficient >90% all through the 1970s. The present United States capacity for MA production is about 1.9 billion lb.
