How do I obtain the Henry's law constant for a component in a multicomponent absorber in HYSYS? I have looked through the entire simulation, but can't seem to find anywhere that HYSYS provides the values for the Henry's law constant. Thankyou.

Hysys doesn't provides the value for Henry's component directly. However, one can simulate a flash column with components of interest in the feed stream at desired pressure and temperature, and obtain the values of component in equilibrium with each other. The ratio of the concentrations (e.g. cg/cl) would give you a reasonable value for Henry's constant.

You may wish to try this out by simulating it for some known systems, and validate with the experimental data, so as to get more confidence on the procedure.

Regards,
Krishna
