Abstract:
A distillation device comprising a column for separating a feed stream into a head product stream, a bottom product stream and optionally one or more side extraction streams, having three or more cells in 5 series through which fluid flows, wherein at least the first cell is integrated into the bottom of the column, for multi-stage heating and partial evaporation of the liquid flowing through the cells with the exception of the liquid from the last cell in an evaporation stage.

Claim (Index 1):
A distillation apparatus comprising a column for fractionating a feed stream into a tops product stream, a bottoms product stream, and optionally one or more side draw streams, having three or more serially liquid-traversed cells,\n wherein at least the first cell is integrated into the bottom of the column for multistage heating and part-evaporation of the liquid traversing the cells, with the exception of the liquid from the last cell, in one evaporator stage in each case, wherein liquid from each of the three or more serially liquid-traversed cells with the exception of the last cell, is passed through an evaporator stage and part-evaporated therein to obtain a part-evaporated stream in each case, which is completely or partially supplied to the respective next downstream cell, and wherein a liquid reflux from one or more of the three or more cells, with the exception of the first cell, into a respective immediately preceding cell is provided.
