Thread: Henry Constant information addition in aspen plus

  1. Post Henry Constant information addition in aspen plus

    i am simulating a case of NOx absorption in aspen plus using radfrac

    five of the components are henry components

    three of them have T-dependent henry constant and are given in the form of Kh= a * exp (b * (1/T-1/To)) ---> 1
    experimental values of a, b and T (temperatures limits for empirical relation) are given

    Now problem i am facing is how to add this information in aspen plus henry constant form.
    In aspen plus it takes the form of
    ln Kh= A + B /T+ C * ln T+ D * T+ E * T^2 ----> 2

    How can i regress my exponential data from equation 1 in the form of equation 2 using aspen plus?
