        the free version has a limited number of chemicals but there are the most common hydrocarbons C1-C13 plus water, ammonia, toluene etc.
        Very good software.

        has anyone experience with the column model in this library?
        I need to solve distillation columns (hydrocarbons) with two (or more) feeds.
        Comments appreciated.

        dbert,
        I have not a large experience but I have spent several hours with free version, the distillation column works well (I have a couple of examples with two feeds) and convergence is reliable even with difficult spec's.
        In my opinion the biggest limit in free version is that you can't define pump arounds, they are supported only in commercial versions, by the way chemsep lite (another free software) does support pump arounds but convergence could be a little problematic.
        Apart from this they are both very good software.

        thanks for the comments,
        I have no pump arounds but multiple feeds and one side drawn, and Peng Robinson should work well in my case.

        I have a couple of comments, too.
        The Excel page included in distribution files doesn't "show" all the features, the method DCOL in library does allow additional specififications as dH on each stage, according the documentation it solves also VLLE and LLE.
        I don't know which are the limits, as max number of stages etc. however according my tests it can solve a 100 stages column without much troubles.
        I have been in contact with Prode to get some assistance and I got answers even I was not interested to purchase the licence.
