Performance of a horizontal column equipped with a rotary gauze-spring packing was evaluated. Through experiments conducted under atmospheric pressure at total reflux, using the cyclohexane-heptane system, separation efficiency, liquid holdup, and pressure drop were measured. Separation efficiency for the horizontal orientation (at 0 degrees) was somewhat better than at 5 degrees, and was expressed in terms of HETP, which ranged from 0.1 to 0.3 m when F-factor ranged from 0.05 to 0.32 m/s(kg/m(3))(1/2) for a speed of rotation of 100 to 600 rpm. Efficiency of the gauze-spring packing was somewhat inferior to that of the screw-brush packing described in our previous work. However, we found that pressure drop of the former can be reduced to one-tenth that of the latter, corresponding to one-hundredth that of a conventional packed column, such as a column having a Sulzer or McMahon packing.
