Subject: Matlab files 


Sigurd,


Here are the Matlab files you asked for. I put them in order and I wrote some more detailed comments so it would be easier to use them.


The column simulated is a batch rectifier and the system is a 3-component one (methanol/ethanol/1-propanol) but it can easily be changed to a continuous column.


Three VLE models can be used (Wilson, UNIQUAC or NRTL). Wilson and NRTL work fine for 2-components (the third is set to zero). However, UNIQUAC does not accept a zero (0) value but a very small value (e.g 0.000001)  for the third component works fine.
