The Performance of a Rotating Module in Oily Emulsions Ultrafiltration

Abstract

Abstract The rotating ultrafiltration module has been applied to concentrated oily emulsions with the aim of checking its practical features. The ultrafiltration yield has been measured as a function of pressure, tangential speed, temperature, oil concentration, and hydrodynamic conditions. An energy consumption evaluation has been performed and a comparison with tubular modules tried. The importance of turbulence promoters and the influence of the radial geometry of the module has been outlined by means of simulation tests with a transparent model system.
