Column having integrated heat exchanger

A column including a column body and at least one heat exchanger installed between two trays within the column, which heat exchanger is operated as a condenser, comprising the heat exchanger being a plate heat exchanger which is integrated into the column body within a collecting vessel open at the top between the two trays in the interior of the column body, so that vapors ascending from a lower tray are conducted past the heat exchanger and are deflected at least in part by 180.degree. at the tray lying above, and then impinge onto the condenser plate where they precipitate as condensate and move downwards together with the vapors to be condensed.

A column including a column body and a head and at least one heat exchanger with condenser plates installed directly on the column head, the heat exchanger comprising a plate heat exchanger constructed and arranged so that overhead vapors ascending from the column body are conducted through an internal cavity and are deflected through 180.degree. at the top of the exchanger and then impinge on the condenser plates, where they precipitate as condensate and move downwards together with the vapors to be condensed, and wherein the plate heat exchanger is mounted in the upper part of the column.

A column including a column body and at least one heat exchanger installed between two packing beds within the column, which heat exchanger is operated as a condenser, comprising the heat exchanger being a plate heat exchanger which is integrated into the column body within a collecting vessel open at the top between the two packing beds in the interior of the column body, so that vapors ascending from a lower packing bed are conducted past the heat exchanger and are deflected at least in part by 180.degree. at the packing bed lying above, and then impinge onto the condenser plate where they precipitate as condensate and move downwards together with the vapors to be condensed.
