Abstract: In an adiabatic heat exchanger, using the principle of kinetic cooling, a carrier gas is forced through a number of narrow, heat-conducting pipes wherein its velocity increases and its temperature drops. Incoming gas is forced to pass over these now cold pipes causing precipitation of a portion of the gas and an increase in temperature of the remaining portion. Such an arrangement permits for example removal of a condensible gas e.g. water vapour from a non-condensible carrier gas without the necessity of using an additional cooling medium.

Abstract: In rotating disc filters used for example in the pulp and paper industry, one or more spray elements are positioned between adjacent discs to rotate about an axis parallel to the disc axis. This arrangement achieves greater washing coverage of the discs than prior systems.
