  • Page 18 3.1 Basic principles of separation 3 Separator Basics Basic principles of separation The purpose of separation can be: to free a liquid of solid particles, to separate two mutually insoluble liquids with different densities while removing any solids presents at the same time, to separate and concentrate solid particles from a liquid.
  • Page 19 3 Separator Basics 3.1 Basic principles of separation 3.1.1 Factors influencing the separation result Separating temperature For some types of process liquids (e.g. mineral oils) a high separating temperature will normally increase the separation capacity. The temperature influences oil viscosity and density and should be kept constant throughout the separation.
  • Page 20 3.1 Basic principles of separation 3 Separator Basics Phase proportions An increased quantity of water in a oil will influence the separating result through the optimum transporting capacity of the disc stack. An increased water content in the oil can be compensated by reducing the throughput in order to restore the optimum separating efficiency.
