reactive distillation

[aken]

Hi. I am trying to explore reactive distillation but when l try to solve l get the message as attached in the picture. Thanks for your help!

Thanks for the response and it finally converged with unconvincing results after changing errors suggested by Prof. Ross Taylor. My question is, in the form where we input the reaction kinetics data, it does not have where we can input the pre-exponential factor and activation energy unlike in the COCO interface. Is the k in the input window for rate constant or reaction rate? I obtained the reaction kinetics data from the following document:

Again quoting Prof. Taylor:

Hi,
I used the exact figures as those given by Professor Taylor in the last comment for the methanol esterification and the figures as obtained from Luyben. But still the conversion of methanol is negligible. Does the feed temperature has to be same as the temperature which the specific rate constant was determined? Please see attached documents.
