Cyclone Separator - an overview | ScienceDirect Topics

Before 2000, only cyclone separators (see schematic in Figure 17) allowed collection of the modifier⧸solute without exposing the operator to aerosols. Cyclones are one form of a gas–liquid or momentum separator. Cyclone separators operate at 20–60 bar. If the mobile-phase density in the column is 0.9 g cm −3 at 150 bar, the density will be ∼0.1–0.15 g cm −3 at 20–60 bar
