The column initialisation is only required for the first inner loop optimisation problem (described in section 6.2). The liquid composition on the plates, condenser holdup tank and in the distillate accumulator (differential variables) at time t = 0 are set equal to the fresh charge composition (xB0) to the reboiler. The DAE model equations are solved at time t = 0 to provide a consistent initialisation of all the remaining variables. The final values of all these variables at the end of the distillation task in each inner loop problem are stored and used for column initialisation for the subsequent inner loop optimisation problems. At the beginning of each task, the distillate accumulator holdup is set/reset to zero. 

Liquid compositions of plates, condenser holdup tank and accumulator (differential variables) at time t=0 are set equal to the fresh charge composition (xB0) to the reboiler. It is also possible to set these values to mixed charge composition (xBC). Reboiler holdup and compositions were initialised to the mixed charge (BC, xBC) at each iteration of PO. Mujtaba and Macchietto (1988) and Mujtaba (1989) considered Type IV-CMH model for the process and the model was solved at time t=0 to initialise all other variables. The first product (D1, xD/) (see Figure 8.2) was drawn off starting from t = 0. For the second distillation task no re-initialisation was required. The distillate was simply diverted to a different product accumulator and integration was continued. 

The column configurations and other parameters are defined in Table 11.11. Thirteen cases were considered using different initial charge compositions and different product purity specifications (same specifications for light and heavy product). The results are summarised in Table 11.11. The results clearly show the cases (shown in bold) when an IBD column is superior to a CBD column. The optimum reflux or reboil ratio profiles for 3 cases are shown in Figure 11.10. Refer to the original reference for further details. 

Azeotropic distillation is appropriate only at high content in aromatics, over 90%. Nonpolar entrainers, such as methanol and acetone, can increase the volatility of nonaromatics by forming low-boiling azeotropes. This method depends strongly on the charge composition, and therefore is not used in industry. 

In Table 5 you ll find properties of some alloys on LaNj -basis produced under industrial conditions designed for each alloy depending on its physical and chemical properties charge composition, temperature of its treatment and time of isothermic exposure, procedures of hydrometallurgical treatment of reaction products. 

Phlegmatized and pressed Cyclonite is used as a highly brisant material for the manufacture of -> Booster and -> Hollow Charges. Non-phlegmatized Cyclonite in combination with TNT is also used as a pourable mixture for hollow charges and brisant explosive charges (-> Compositions fi) mixtures of Cyclonite with aluminum powder are used as torpedo charges (Hexotonal, Torpex, Trialen). Cyclonite may also be used as an additive in the manufacture of smokeless powders. 

DEMOLITION - The last two formulas will be comparable to T.N.T. in shaped charge application, but require very large boosters. The last two charge compositions would be the only explosive "Ammonexes" suitable, as the other two have much too low of a detonation rate.
