The processes covered by this sub-class include evaporation, distillation, crystallisation, filtration, dust precipitation, gas cleaning, absorption, adsorption.
This sub-class also includes similar processes which are not concerned with, or limited to, separation (except in the case of absorption or adsorption).
The word "filtration" and related words should be interpreted as embracing straining liquids from solids.

Note(s)
The term "solid particles" is to be read as covering such particles whether catalysts,
"Fluidised particles" are to be understood as finely divided solid particles lifted and agitated by a stream of fluid.
"Fluidised-bed technique" relates to fluid-solid contacting technique in which finely divided particles are lifted and agitated by a rising stream of fluid, said stream having such a speed as to form a lower dense phase (the "bed") and an upper dilute fluidised phase of "fluidised particles".
This sub-class is intended to take only laboratory apparatus which is either applicable solely to laboratory purposes or which, by reason of its simple construction and adaptability, is such as would not be suitable for industrial use.
