The plantwide control deals, mainly, with the mass balance of the species involved in the process. The species inventory can be maintained based on two different principles, namely self-regulation and feedback control. Control structures based on self-regulation set the flow rates of fresh reactants at values determined by the production rate and stoichiometry. Control of inventory by feedback consists of fixing one flow rate in each recycle loop, evaluating the inventory by means of concentration or level measurements, and reducing the deviations from the setpoint by change of the feed rate of fresh reactants. 

Aldehyde photolysis (35) is another branch of the mechanism that must be absorbed in the rates and stoichiometry of a lumped parameter scheme.

The accuracy of our understanding of photochemical mechanisms is an additional source of uncertainty. Known uncertainties in photochemical reaction rates and stoichiometries cause an uncertainty of 20% in calculated ozone formation rates (Gao et al., 1996). 

According to these reactions, the relative rates of formation of alkenyl carbonium ions should depend on solute structure in the observed order. Moreover, both the rates and stoichiometry of SO 2 evolution should show structural dependence. 

H] 1 X 10" g atom cm" . At atom concentrations less than about 2 X 10" g atom cm , the dependence of fluorescence intensity upon atom concentration is strictly linear, thus simplifying calibration and kinetic analysis. Calibration of the extremely low atom concentrations required is carried out by production of known atom concentrations by reacting very small metered amounts of a stable reactant with excess of a suitable atomic species e.g. Cl, Br and I Pj/2 atoms are generated by the following reactions of known rates and stoichiometries... 

Detailed studies of the reaction kinetics [15] carried out at Bayer revealed a complex reaction mechanism (Figure 10.2). Kinetic parameters obtained in the study explain the polymerization rate and stoichiometry of oxidized PEDT. The first step in the mechanism, EDT oxidation to a radical cation.

COMMENTS The cathode would also absorb some electrolyte vapor as well and, since the flow rate and stoichiometry are higher on the cathode, would absorb more. On the cathode, the solution is slightly more complicated since water vapor generated from reaction will also be vaporized into the flow. From this calculation, one can see how even a small decrease in the vapor pressure can greatly extend the operational lifetime of the stack. 

V. (The polymer prepared at = - 1400 Volt does not follow that overall tendency). On the average the total polymer composition is reduced in fluorine content (F/C ratio decreasing) with Vj potential from 1.54 to 1.40. Noteworhty is the particular shape of the spectrum recorded for polymer D-1 all the components of the Cls region are especially well resolved if we add that the deposition rate for this film was slow, and that the shape of spectrum D-1 can be related to a more "regular" (stoichiometric) nature of the film we found some correlation with the work of Lehman who noted a relation between deposition rate and stoichiometry.
