High-pressure homogenization is widely used in continuous
processing of emulsions to obtain highly valuable products, such
as for foods, pharmaceuticals, fuels, and paintings. In general, the
objective of this energy intensive process is the formation of an
emulsion with a specific droplet size distribution in the micron to
sub-micron scale. Pressures up to several 1000 bar are used to force
the liquid through homogenization units with small cross-section
areas, such as valves or orifices
