Abstract: Shell-and-tube heat exchanger having an inlet opening for product vapour, inlet and and outlet openings for cooling agent which is conducted in the heat exchanger (transfer) tubes, a purge stub for removing inert gases, and a discharge stub for product condensate, in which a) the shell-and-tube heat exchanger (1) is arranged vertically, b) the arrangement of the heat exchanger tubes (2) in the region of the side where the product vapour flows at first has large spacings, which are increasingly reduced in the course of the path of the main flow, and c) a plurality of purge stubs for inert gases (5) are arranged one above another opposite the inlet opening for product vapour (4) in the region of the tightest packing of the heat exchanger tubes (2).
