Abstract
A method for the use of a porous, preferably dimensionally stable, particulate material in a packed filter bed for separating a disperse liquid phase from a gas and/or separating a disperse liquid phase from a liquid, with the average size of the particles being in the range of from 0.1 to 10 mm and the internal surface area of the material being such that, after it has been filled with the disperse liquid phase to be separated and placed, as a packed bed, at a distance of from R to r from the center in a centrifuge rotating at an angular velocity w, for which it holds that EQU 0<w.sup.2 (R.sup.2 -r.sup.2).ltoreq.20 (rad/s).sup.2 m.sup.2, wherein w stands for the angular velocity (in rad/s) and R and r represent the largest and the smallest radius (in m), respectively, of the material in the centrifuge, at least 1% of the liquid will have been separated after 5 minutes, while at least 10% of the liquid will have been separated after 60 minutes is disclosed.
