Abstract

The present invention further relates to a process for removing a target product from a liquid phase P comprising the target product.

First claim

The invention claimed is:

1. An apparatus ( 1 ) for separation of a target product from a liquid phase P comprising the target product, comprising
a plurality of primary spaces ( 3 ) for a heat transfer medium W and a plurality of cooling disks ( 103 ), each primary space located within each cooling disk,
lines having surfaces which conduct the heat transfer medium W,
a first feed unit ( 5 a ) and a first removal unit ( 5 b ) for the heat transfer medium W,
a plurality of secondary spaces ( 7 ) for the liquid phase P,
a second feed unit ( 9 ) for the liquid phase P,
a plurality of crystallization surfaces ( 13 ), each crystallization surface located within each cooling disk, and each crystallization surface divides each primary space from the secondary spaces ( 7 ),
a second removal unit ( 15 ) for the target product, and
a plurality of application units ( 11 ) for distributing a liquid phase P 0 essentially directly to the crystallization surfaces ( 13 ) and the surfaces of lines that conduct the heat transfer medium W, wherein one or more of the plurality of application units ( 11 ) are arranged for each cooling disk.

2. The apparatus ( 1 ) according to claim 1 , wherein each application unit ( 11 ) comprises a pipeline system having nozzles for distributing the liquid phase P 0 over each crystallization surface ( 13 ) of each cooling disk ( 103 ) and the surfaces of lines that conduct the heat transfer medium W.

3. The apparatus ( 1 ) according to claim 1 , wherein the liquid phase P 0 comprises at least one of the liquid phase P and a liquid phase P 1 comprising a solvent.

4. The apparatus ( 1 ) according to claim 1 , further comprising a heat exchanger ( 19 ) for the heat transfer medium W, arranged upstream of the first feed unit ( 5 a ).

5. The apparatus ( 1 ) according to claim 1 , wherein the apparatus ( 1 ) is a cooling disk crystallizer.
