Simulation Programs for

Computer simulation programs for process design optimization have been developed for the PUREX process utilizing these relationships (22). A subroutine has also been developed which describes the behavior of fission products (23).

The UNIQUAC equation is not given here as its algebraic complexity precludes its use in manual calculations. It would normally be used as a sub-routine in a design or process simulation program. For details of the equation consult the texts by Reid et al. (1987) or Walas (1984). 

Procedures for the sequencing of columns are also available in the commercial process simulator programs for example, DISTIL in Hyprotech s suite of programs (see Chapter 4, Table 4.1). 

We would like to thank the beamline scientists of ID 15 of the ESRF. T. Buslaps, V. Honkimaki, A. Shukla and P. Suortti for their valuable help with the measurements and F. Maniawski and J. Kwiatkowska for their help with the sample preparation. We are also grateful to J. Felsteiner for sending us his Monte-Carlo simulation program for the multiple scattering correction. 

Simulation programs for the ESR line shapes of peroxy radicals for specific models of dynamics have been developed for the study of oxidative degradation of polymers due to ionizing radiation [66]. The motional mechanism of the peroxy radicals, ROO, was deduced by simulation of the temperature dependence of the spectra, and a correlation between dynamics and reactivity has been established. In general, peroxy radicals at the chain ends are less stable and more reactive. This approach has been extended to protiated polymers, for instance polyethylene and polypropylene (PP) [67],...

Structural characterizations of the immobilized bilayer assemblies are essential for the molecular design of the functional materials. On the bases of the systematic crystallographic investigation of single crystals of double-chain ammonium amphiphiles [9], Okuyama wrote a computer simulation program for the calculation of bilayer structures in cast bilayer films and bilayer thicknesses estimated from the repeating period in the X-ray diffraction data have been exclusively used for structural discussions [10,11].

Figure 8.3-2 shows the simplified flow-sheet used in the simulation program. For plantmodelling, the solution was considered to be constituted of only CO2 and THF. The dissolved polymer and drug were neglected. Because of the low concentration of these compounds in the feed, this approximation should not have significant consequences. 

Technically, COSMO-RS meets all requirements for a thermodynamic model in a process simulation. It is able to evaluate the activity coefficients of the components at a given mixture composition vector, x, and temperature, T. As shown in Appendix C of [Cl 7], even the analytic derivatives of the activity coefficients with respect to temperature and composition, which Eire required in many process simulation programs for most efficient process optimization, can be evaluated within the COSMO-RS framework. Within the COSMOt/ierra program these analytic derivatives Eire available at negligible additionEd expense. COSMOt/ierra can Eilso be csdled as a subroutine, Euid hence a simulator program can request the activity coefficients and derivatives whenever it needs such input. 

You may easily obtain these K values from a process simulation program for your particular case. If you do not have this source, use Chap. 2 of this book or the program RefFlsh, which is included in the com-...

Shortcut calculations can be quite useful to the process designer or run-plant engineer they may be used to outline process requirements (stream and equipment sizes) early in a design project, to check the output of a process simulation program for reasonableness, to help analyze or troubleshoot a unit operating in the manufacturing plant or pilot plant, or to help explain performance trends and relationships between key process variables. In some applications involving dilute...
