Faster, more flexible and environmentally benign chemical production are the three base elements for the F -Factory visionary project. Rapid response to market...

The F -Factory is not only a crucial step and a prerequisite for successful and competitive future processes in Europe and worldw ide, but is also the basis to implementing a new sustainable industrial chemistry. A major objective w ill be a substantial drop in capital expenditure for new plant and/or for retrofit of high-performance intensified devices into existing infrastructure. 

The lAP also contains an introduction to three visionary projects that will practically demonstrate the benefits and impact on daily life of the sustainable industrial chemistry (i) the Smart Energy Home, (ii) the Integrated Biorefinery, and (iii) the F Factory the latter has already been discussed in this chapter. 

The methods of analysis that we have presented thus far may be generalized to the case of a f factorial design, that is a design with k factors each at two levels. The statistical model for... 

MI cables can maintain temperatures up to 1200°F and withstand exposure to up to 1500°F. The major disadvantage of Ml cable is that it must be factory-fabricated to length. It is very difficiilt to terminate or splice the heater in the field. This means pipe measurements are necessary before the heaters are ordered. Also, any damage to an MI cable generally requires a complete new heater. It s not as easy to splice in a good section as with self-regulating heaters. 

A distribution network 33 kV, three-phase 50 Hz feeding an industrial belt with a number of medium-sized factories some with non-linear loads and some with static drives and some with both. It was observed that while the lines were apparently running reasonably loaded, the active power supplied was much below the capacity of the network. Accordingly, a harmonic study of the network was conducted and it was found that despite localized p.f. control by most factories, the p.f. of the network itself was well below the optimum level and the voltage was also distorted by more than was permissible. To improve this network to an acceptable level, we have considered the following load conditions, as were revealed through the analysis. 

It is tempting to use Eq. (7) to derive Eq. (6), because they have similar forms given the relationship of the F function to the factorial. But the binomial and the beta distribution are not normalized in the same way. The beta is nonnalized over the values of 0, whereas the binomial is nonnalized over the counts, y given n. That is.

The final structure of resins produced depends on the reaction condition. Formaldehyde to phenol (F/P) and hydroxyl to phenol (OH/P) molar ratios as well as ruction temperahne were the most important parameters in synthesis of resols. In this study, the effect of F/P and OH/P wt%, and reaction temperature on the chemical structure (mono-, di- and trisubstitution of methyrol group, methylene bridge, phenolic hemiformals, etc.) was studied utilizing a two-level full factorial experimental design. The result obtained may be applied to control the physical and chemical properties of pre-polymer. 

A two levels of full factorial experimental design with three independent variables were generated with one center point, which was repeated[3]. In this design, F/P molar ratio, Oh/P wt%, and reaction temperature were defined as independent variables, all receiving two values, a high and a low value. A cube like model was formed, with eight comers. One center point (repeated twice) was added to improve accuracy of the design. Every analysis results were treated as a dependent result in the statistical study. 

A two level full factorial experimental design with three variables, F/P molar ratio, OH/P wt %, and reaction temperature was implemented to analyses the effect of variables on the synthesis reaction of PF resol resin. Based on the composition of 16 components of 10 samples, the effect of three independent variables on the chemical structure was anal3 ed by using 3 way ANOVA of SPSS. The present study provides that experimental design is a very valuable and capable tool for evaluating multiple variables in resin production.

Not surprisingly, F defines the factorial under this interpretation. Later in this section we shall see how to verify programs with recursion. This full expansion is somewhat clumsy, and we would probably take the liberty of expressing the computation in this abbreviated form ...
