Choice of Separator for Heterogeneous Mixtures

Choice of Separator for Heterogeneous MixturesBy JuwariSource Robin Smith Separation of the different phases of a heterogeneous mixture should be carried out before homogeneous separation, taking advantage of what already exists. Phase separation tends to be easier and should be done first. The phase separations likely to be carried out are:

Gasliquid (or vaporliquid) Gassolid (or vaporsolid) Liquidliquid (immiscible) Liquidsolid Solidsolid.The principal methods for the separation of heterogeneous mixtures are:

Settling and sedimentation Inertial and centrifugal separation Electrostatic precipitation Filtration Scrubbing Flotation Drying
