Indian Patent No. 204956 recorded in register of
patents on April 19, 2007
Abstract:
The present invention relates to an energy efficient
and inexpensive Freeze Concentration System (FCS)
to selectively freeze solvent from a solution using
Heat Pump (HP) with heat transfer surfaces to extract
and deliver heat to freeze the solvent and melt
the frozen solvent using the heat from the HP thereby
implementing an energy efficient Freeze Concentration
Process (FCP). It further relates to the FCP wherein
one or more sets of the heat extracting and/or
heat delivery surfaces are intermittently operated
as either freezing or melting surfaces to concentrate
solution in a batch process or batch wise continuous
process. It also relates to the FCP wherein two
or more sets of heat extracting and heat delivery
surfaces are continuously operated as freezing
and melting surfaces to concentrate solution in
a continuous process.
