Size application

In Table 9 the recent statistics of ATES utilisations in Sweden are presented. As can be seen the technology is so far preferably used for commercial and institutional buildings with small or medium sized applications. Large-scale plants are applied for some district heating and cooling systems while the industry sector only has a couple of systems applied for manufacturing industries. The rest represents cooling in the telecom sector.

The AKDs are used in paper sizing applications. Paper sizing chemicals provide paper and paperboard with resistance to wetting by liquids, especially water repellency in paper cups, milk cartons, photographic paper, coatings, and packaging paper (139) (see Paper Papermaking additives). 

Despite the complexity analysis results for the combinatorial nature of MILP models of the form (1), several major algorithmic approaches have been proposed and applied successfully to medium and large size application problems. In the sequel, we will briefly outline the proposed approaches and subsequently concentrate on one of them, namely, the branch and bound approach. 

X-ray scattering from coal was the subject of several early studies which led to the postulation that coal contains aromatic layers about 20 to 30 A in diameter, aligned parallel to near-neighbors at distances of about 3.5 A (Hirsch, 1954). Small-angle x-ray scattering, which permits characterization of the open and closed porosity of coal, has shown a wide size distribution and the radius of gyration appears to be insufficient to describe the pore size. Application of the Fourier transform technique indicated that some coals have a mesoporosity with a mean radius of 80 to 100 A (Guet, 1990). 

The expected levels of drift deposit are from 10 ng/square foot at 1/4 mile to 1 ng/square foot at 1 mile. In utilizing averaged data it must be understood that variations in drop size, application methods, meteorological conditions, or terrain can increase or decrease the drift deposition by 10 fold or one can imagine, in oder to be ultra conservative, even as much as 1,000 fold. 

The more complex Mie Theory (lj must be invoked to analyze particles with dimensions near the wavelength of light. Fraunhofer theory is an interference phenomenon, and is described in various optics text books (.2,3.). It is adequate for most particle sizing applications and will be discussed in detail. Mie Theory requires a knowledge c the refractive index of the material. A unique use of polarized side scatter at several wavelengths is employed to obtain particle size channels in the submicron region. 

Downcomer aeration factor prediction. The fractional liquid holdup varies from about 0.3 in the froth zone to close to unity in the clear liquid zone (Fig. 6.12a). The height of each zone is a complex function of system properties, operating conditions, and downcomer geometry. This makes it practically impossible to theoretically predict the average downcomer aeration factor <(>. . Correlations in the literature (e.g., 46) are based on limited data obtained in atmospheric pressure simulator work with small downcomers. It is therefore difficult to recommend them for commercial-size applications. Zuiderweg (17) presented a plot of downcomer aeration factors derived theoretically from commercial-scale high-pressure flood data. However, the plot is based on a handful of data and is therefore difficult to recommend for general aeration factor prediction. 

Heterodyne experiments measure a linear function of g(1) and therefore produce if111 data with improved signal-to-noise ratio due to removal of the errors 113 introduced by the square root in Eq. (50). However, particle sizing applications rarely employ this approach because of experimental difficulties 113,50] and the sensitivity of heterodyne experiments to collective particle motions.
