Plants comparisons

We also give calculations of the performance of some of these various gas turbine plants. Comparison between such calculations is often difficult, even spot calculations at a single condition with state points specified in the cycle, because of the thermodynamic assumptions that have to be made (e.g. how closely conditions in a chemical reformer approach equilibrium). Performance calculations by different inventors/authors are also dependent upon assumed levels of component performance such as turbomachinery polytropic efficiency, required turbine cooling air flows and heat exchanger effectiveness if these are not identical in the cases compared then such comparisons of overall performance become invalid. However, we attempt to provide some performance calculations where appropriate in the rest of the chapter. 

Wong, J.M. Maroney, P.M. Pilot plant comparison of extended aeration and PACT for toxicity... 

Wong and Maroney [49] reported on a pilot plant comparison of PACT and extended aeration (activated sludge) for treating petroleum rehnery wastewater. Results indicated that although both processes performed similarly in COD removal, only the PACT system yielded an effluent meeting the discharge requirements for whole effluent toxicity reduction. Similar results in toxicity reduction have been reported for wastewaters from other industries [50]. 

Pilot plant data for fluid catalyst hydroforming of East Texas heavy naphtha are summarized in Table X, and are compared with fixed-bed hydroforming pilot plant data in Figure 6. Comparative data on the East Texas naphthas employed in the pilot plant comparison of Figure 6 are shown in the following tabulation ... 

In this example, internal consistency, over time, can suffice to assure production, with minimal analytical cost, of acceptable alloy. Indeed, portions of previous batches which have yielded high-quality materials and products can serve as measurement standards without the need for traceability to SI or national standards. Measurement traceability to a higher laboratory may be useful in attaining certain objectives, such as inter-plant comparisons and reaching agreement between producer and buyer laboratories, but, it is not essential to immediate quality assurance for production in a single plant.

Negative observations of this nature should be treated with caution in view of the positive correlations obtained by other workers, and also because inter-plant comparisons would not be expected to elicit as consistent a correlation trend as for tests on a single plant.4,5... 

A chloroplast location of the gene for Cyt / was suggested by two plastome mutants of Oenothera which were deficient in spectrally detected Cyt/[102], and by the maternal mode of inheritance of Cyt /in interspecific Fj hybrids of Nicotiana [103]. The structural gene (petA) for the Cyt / polypeptide was initially localized and characterized from pea chloroplast DNA [104,105], and subsequently from wheat [106], spinach [107] and Oenothera [108]. Open reading frames of 320 codons have been detected in chloroplast DNA from each of these plants. Comparison with the determined N-terminal sequence of Cyt / indicates the presence of a 35 amino acid residue pre-sequence and a mature polypeptide of 285 amino acid residues. A putative haem-binding site, Cys-Ala-Asn-Cys-His, is located near the... 

Comparison of leaves and culms of mature plants. Comparisons were made between volatiles steam distilled from leaves and culms (hollow stems) of mature plants which were 40-50 cm tall (Figure 1). Rusts manifest different affinities for these plant parts. Plants were harvested, stored refrigerated overnight and leaf blades were cut from the culms and both parts were cut into 3-6 cm segments. The results from these comparisons are presented in Table III. With... 

There exist a large number of mechanistic models for organic phosphorus transformation processes in aquatic systems. However, different approaches have been chosen to describe different aquatic systems (rivers, lakes, ocean, sediment, sewage treatment plants), comparison of which is complicated...
