The design options of a gravity separator are still limited and rely on the study of settling behavior. A methodology will be presented were an experimentally given inlet droplet size distribution (DSD) is the basis for the calculation of the dispersion layer in a gravity separator. A pilot scale of a continuous gravity separator is presented and CFD results are validated. A transmitted light measurement technique for the determination of the DSD is presented up to a holdup of 25% dispersed phase. The resulting DSD was in the range of 20-2000 μm depending on flow rate and phase ratio. Furthermore, correlations of the real DSD with the settling behavior of the dispersion in a settling cell are discussed. The new approach to the description of gravitational separators will be presented and the applied CFD methods showed good results with the system water/paraffin.
