Influence of fluid properties on the hydrodynamics and operability of a countercurrent supercritical packed column

•Liquid hold-up and pressure drop do not reliably indicate operability in SF fractionation columns.•No observable “loading” operating regime was found under SF conditions.•Changes in temperature had a significant impact on operability due to fluid property variation.•Column operability range decreas...
