ABSTRACT:
Column having integrated heat exchanger
A column is described including a column body (1) and at least one heat exchanger (2) installed directly on the column head. This heat exchanger is a plate heat exchanger which is specially arranged so that the condensing vapors and the condensate (12) generated on the exchanger surface move in one direction.
A further embodiment of the invention relates to a column which contains a column body (1) and at least one plate heat exchanger installed between two trays and/or packing beds within the column, which plate heat exchanger is operated as a condenser and is situated within a collecting vessel (29) open at the top.
A third embodiment of the invention relates to a column which includes a column body (1) and at least one plate heat exchanger (2), which is operated as an evaporator, and which is installed within the column between two trays and/or packing beds and/or in the bottom.
The column according to the invention is distinguished by a space-saving construction.
