Abstract: The invention relates to a bath condenser with a condenser block (1) that has evaporation passages (8) for a liquid and liquefaction passages (2) for a heating medium. The condenser block (1) has at least two circulation sections (7) that are located on top of one another, the evaporation passages (8) each having on the lower end of a circulation section (7) at least one entry opening (9) for the liquid and on the upper end of the circulation section (7) at least one exit opening (10). Only exit openings (10) and entry openings (9) that are located on the same side (12) of the condenser block (1) are connected via means (17, 30) for routing the liquid.

Abstract: The invention relates to a reactor for performing a strongly heat-conditioned catalytic reaction in a process fluid, equipped with plates that are arranged parallel to one another at a distance and that form flat channels with lateral boundary areas that face one another, whereby a portion of the channels contains a solid catalyst and carries the process fluid, and another portion of the channels guides a heat transfer medium in indirect heat contact with the process fluid.

Abstract: An apparatus for fractionating a gas mixture at low temperature includes (1) a separation column; (2) a heat-exchanger block comprising a main heat-exchanger section and a condenser/evaporator section, wherein the condenser/evaporator section has evaporation passages and condensation passages; (3) a first feed gas line for supplying feed gas to the main heat-exchanger section; (4) a second feed gas line for introducing cooled feed gas into the separation column; (5) a first liquid line leading from a lower region of the separation column to an inlet of the evaporation passages; (6) a gas line that leads from an upper region of the separation column to the condensation passages; (6) a reflux line to introduce condensate which is formed in the condensation passages into the upper region of the separation column; (7) a phase-separation device connected to an outlet of the evaporation passages; and (8) a second liquid line leading from the phase-separation device to an inlet of the evaporation passages and also c
