Ternary mixtures with non-ideal VLE using Wilson or Uniquac equation. (data are now for a column similar to "column A" with 41 stages but this can easily be changed). Files: 'colamod_nonideal': The main dynamic model for a ternary mixture with non-ideal VLE modelled by either WILSON or UNIQUAC equation. The user can choose (line 65-66 of the file) which VLE model she/he wants to use. The Francis Weir formula is used for liquid holdup dynamics. Note that an algebraic equation is added for the pressure at each stage to compute the temperature. Temperature is then used as an extra state. This avoids a separate time consuming "inner-loop"Tbubble point calculation. 'cola_lv_nonideal'. Subroutine for simulating column using the LV configuration. Sets the data for the feed. 'run_colamod_nonideal': File for running the main program. This file specifies the initial states and returns the results. 'wilson': VLE model that uses Wilson equation for the liquid activity coefficients. 'uniquac': VLE model that uses UNIQUAC equation for the liquid activity coefficients. I hope that the files in your web-page are more 'user-friendly' now and ready to be used by other people. Stathis Skouras
