October 2000 - Due to the increased needs for coating materials in the paper
industries, there is a world-wide demand for evaporation plants for calcium
carbonate suspension and kaolin.
Generally, multi-effect forced
circulation evaporators are used for the concentration. Since the quantities of
the products to be concentrated are very large, the energy requirement plays an
important role.
GEA Wiegand – one of the leading companies in the
evaporation and concentration technologies - developed a new process which
allows a considerable reduction of the energy consumption of these plants using
different evaporator types, thus increasing the economic viability to a large
extent
