F reduction

Reducing the operating temperature. Consider adding an intercooler on the absorber. Minimize lean oil temperature. Consider the use of a chiller. Each 10°F reduction in lean oil temperature will increase C3 s recovery about 0.8% (Figure 9-11). 

With the incorporation of an economizer into a boiler system, typically a 1% gain in boiler efficiency can be achieved for every 40 to 50 °F reduction in stack temperature.

Figure 5. Successive UV-vis spectra of silver particle evolution and fluorescein (F) reduction in aqueous CTAB solutions containing [AgNOj] = 10 M, [CTAB] = 0.01 M, [NaBHJ = 5xl0 M and [F] = 5xl0 M. (Reprinted from Ref [28], 1999, with permission from American Chemical Society.)...

Figure 32 presents the fit of Eq. (63) to the cross-link data. The shaded area displays the constant EISF contribution to S(Q,t). A combined fit to all spectra yields W/4 = 0.84 1013 A4s 1 and rate fixed to the value obtained from the joint fit. The obtained molecular mass melt of linear PDMS chains in very good agreement with the prediction of a 2/f reduction [see Eq. (64)]. 

Using O2 as the PB (and in the absence of diethyl malonate) 2-tosyloxycyclohexanone gave, after 2 F reduction at the potential of 02 -formation, exclusively methyl cy-clopentanecarboxylate (75%) when Mel was added after the electrolysis [126, 127].

Exposure of ferri-heme-hemopexin to imidazole or KCN can displace one or both of the heme coordinating His residues, but millimolar concentrations are required (138). Other potential ligands such as azide or fluoride are inactive. This coordination stability of the ferri-heme-hemopexin bis-histidyl complex, despite the exposed heme site, is home out by thermal imfolding studies (Section IV,F). Reduction of the heme-hemopexin complex, however, has dramatic effects on its stability. 

In the cathodic scan, reduction of Ph02 (peak F), reduction of PhO (peak G), and reduction of Ph(OH)2 (shoulder H) can he observed on the voltammetric curve.
