DODS SOFTWARE PACKAGE

The DODS software package can be used to complete most of the examples and tutorials in this book. The package has been written in Matlab, but has been complied such that it may be used on a computer without Matlab installation. It is also useful as an independent design tool and, as shown in the examples in the book, the results obtained can be used as initialization to rigorous simulation packages such as Aspen Plus . The DODS package consists of five independent packages ... 

DODS-ProPlot. This is a comprehensive profile plotting package which allows the user to plot single profiles, entire CPMs and ROMs, and their associated pinch points. There are 13 systems to choose from, each of which may be modeled either with a modified Raoult s law and the NRTL activity coefficient model, or with the ideal Raoult s law (does not model azeotropes), or with a constant relative volatility approximation where the software automatically determines the relative volatilities between components (this model also cannot account for azeotropic behavior). One also has the option to insert one s own constant volatilities. It is possible to plot the full DPE, the shortened DPE at infinite reflux (shown in Chapter 7) or the classic residue curve equation. Depending on the equation chosen, the user is free to specify any relevant parameters such as an R value, difference points, system...
