Major results

One of the major results Berman et al. obtained is that the mole ratio of Ca in the absorbent to S in the flue gas has the most important effect. The experimental results for the influence of the Ca/S ratio on the sulfur-removal efficiency, jjs, at different concentrations of C02 in the flue gas are shown in Fig. 7.7. These data were obtained in a reactor with two co-axial cylinders the experimental conditions were flue gas flow rate Vo = 0.001 m3-s 1, diameter of Cylinder I in the reactor D, = 0.06 m, diameter of flue gas exit of the nozzle d = 10 mm, clearance between Cylinders I and II A2 = 5 mm. The results in Fig. 7.7 show the significant influence of C02 in flue gas on the sulfur-removal efficiency %. The reason for this is clear C02 reacts with the absorbent Ca(OH)2, too  

In addition, the influences of some of the operation conditions and the structural parameters of the reactor were also studied. The major results they obtained were as follows  

The results described in item (4) demonstrate that in the absorption equipment used by Berman et al. the third region mentioned in Section 7.4.1, i.e. the walls of the cylinders, makes a significant contribution to the absorption. 

The researchers interpreted the mass transfer coefficient with the mass transfer model for absorption, and the resulting empirical relationships represent the Sherwood number Sh as a function of Reynolds number Re. For details, the reader may refer to Ref. [25]. It is clear that the items included in the relationships they obtained are related closely to the reactor structure. 

The optimal operating conditions determined by Berman et al. are as follows

For the effective diffusivity in pores, De = (0/t)D, the void fraction 0 can be measured by a static method to be between 0.2 and 0.7 (Satterfield 1970). The tortuosity factor is more difficult to measure and its value is usually between 3 and 8. Although a preliminary estimate for pore diffusion limitations is always worthwhile, the final check must be made experimentally. Major results of the mathematical treatment involved in pore diffusion limitations with reaction is briefly reviewed next. 

Water contamination is a constant threat. The sources of water are many—atmospheric condensation, steam leaks, oil coolers, and reservoir leaks. Rusting of machine parts and the effects of rust particles in the oil system are the major results of water in oil. In addition, water forms an emulsion and, combined with other impurities, such as wear metal and rust particles, acts as a catalyst to promote oil oxidation. 

The prime design objeetive of the filter system is to proteet the gas turbine. The performanee of the gas turbine inlet-air filter system has important and far-reaehing influenees on overall maintenanee eosts, reliability, and availability of gas turbines. There are three major results of improper air filtration (1) erosion, (2) fouling of the axial-flow eompressor, and (3) eorrosion of the gas turbine hot-gas path inlets. The importanee of the inlet-air filter, as it relates to eaeh of these three phenomena, ean be appreeiated if...

Here we briefly summarize some major results of solid state theory that are relevant for understanding the behavior of adsorption on surfaces. For a more detailed description please consult excellent books such as S. Elliot, The Physics and Chemistry of Solids (1998), Wiley Sons, New York N. Ashcroft and N.D Mermin, Solid... 

In order to calculate particle size distributions in the adsorption regime and also to determine the relative effects of wavelength on the extinction cross section and imaginary refractive index of the particles, a series of turbidity meas irements were made on the polystyrene standards using a variable wavelength UV detector. More detailed discussions are presented elsewhere (23) > shown here is a brief summary of some of the major results and conclusions. 

The N4 complexes are rather stable in acidic solutions. However, sometimes the stability is not high enough, particularly so at higher temperatures. It was quite unexpected, therefore, to hud that after pyrolysis at temperatures of 600 to 800°C the catalytic activity of these compounds not only failed to decrease but in some cases even increased. The major result of pyrolysis is a drastic increase in catalyst stability. Tests have been reported where after pyrolysis such catalysts have worked for 4000 to 8000 h without activity loss. The reasons for the conservation of high activity after pyrolysis are not entirely clear. The activity evidently is associated with the central ion that has attained a favorable enviromnent of pyrolysis products. 

In fact there is substantial structural variability among the five instances of the helical tubuland structure described above, in the form of variable placements of the diol hosts along the twofold axes, and variable a dimensions of the lattice, both of which have marked influence on the size and shape of the canals. Full analysis of these effects is provided elsewhere 8) and the major results only are reported here. As a consequence of steric repulsions between the bridge on the syn face and methyl substituents R on adjacent molecules presenting an anti face to the canal, as shown in Fig. 8, the molecules presenting the anti face are moved along the twofold axes, farther... 

This synthesis fails when secondary or tertiary halides are used because the alkynide ion acts as a base rather than as a nucleophile, and the major results is an E2 elimination. 

The accident investigation report is the major result of the investigation. In general, the format should be flexible and designed specifically to best explain the accident. The format may include the following sections (1) introduction, (2) process description (equipment and chemistry), (3) incident description, (4) investigation results, (5) discussion, (6) conclusions, and (7) layered recommendations. 

The biosynthesis of eicosanoids utilizes several enzymes till the ultimate bioactive ligand is obtained. The literature is very rich in PAL studies on these enzymes and the local hormone receptors therefore only some major results on the key biotransformations and receptors are represented here. 

The results in Figure 6.9 show that the production rate of readily biodegradable substrate (Ss) by the anaerobic hydrolysis is larger than the removal rate. It is a major result that readily biodegradable substrate is not just preserved but produced. This fact has positive implications on the subsequent treatment processes in terms of denitrification and biological phosphorus removal. On the other hand, it is negative if wastewater treatment is only required in terms of BOD removal. 

As mentioned in the introductory section of this chapter, dediazoniation was reviewed in a volume of The Chemistry of Functional Groups series relatively recently (1983)2 and again in more detail in a monograph in 19947f. Therefore, we will concentrate here on a selection of major results published since the early 1980s on mechanisms of dediazoniations and on applications of dediazoniations in organic synthesis. 

In a subsequent study, Agrawal, Raff and Thompson showed that the sticking probability for the molecule was independent of the interactions used for the substrate atoms. The mobility of the H atoms and the rate of energy transfer between the H atoms and the substrate, however, were reported to depend somewhat on the lattice. Despite the small dependence on the substrate model, the major results of the initial study remained unchanged.

The major results described could be partially anticipated from those previously reported for linear polyethylene (17) as well as those for cis polyisoprene. (] ) For the latter polymer, by taking advantage of its crystallization kinetic characteristics, it was possible to compare the relaxation parameters of the completely amorphous and partially crystalline polymer (31% crystallinity) at the same temperature, 0°C. This is a unique situation and allows for some unequivocal comparisons. It was definitively observed that for all the carbons of cis polyisoprene the T] s did not change with crystallization. 

Polyphosphide compounds within the scope of this overview rely heavily on contributions by von Schnering et al. (for a review on polyphosphides, see [86]), and major results concerning the heavier homologues As, Sb, and Bi are due to Rohr et ah, Eisenmann et al., and Belin et al. 

One of the major results of SEC-GC-MS studies is the discovery of an orderly pattern, by which various isomers and homologs of similar chemical species exist in coal liquids. For example almost any direct coal liquefaction process produces very similar species, which differ from each other by size and extent of isomerization but with an orderly distribution pattern. Alkanes...

Recently, we have shown that whenever qubits collectively couple to common bath modes (e.g., in ion traps [119,120] or cavities [121-123]) local modulations of individual qubits can eliminate cross-decoherence. Our major result is that the modulation must be faster than the correlation time of the bath, but can be much slower than the (unmodulated) multipartite coherence time and still be effective.
