Apparatus with integrated condenser and separator

An apparatus for separating a condensable reaction product from a process gas mixture comprising:

• a pressure jacket having an interior, wherein at least a first process unit and a second process unit are fluidically interconnected and arranged one atop the other in the interior;
• wherein
• the first process unit is configured for condensing the reaction product from the process gas mixture and the first process unit is in the form of a plate heat exchanger and
• the first process unit comprises a multiplicity of plates arranged vertically and parallel to one another with traversable plate interiors and plate interspaces are present between adjacent plates, wherein the plate interspaces are traversable from top to bottom by the process gas mixture and the plate interiors are traversable, from bottom to top, by a cooling medium;
• the second process unit arranged below the first process unit, wherein
• the second process unit is fluidically connected to the plate interspaces of the first process unit and wherein:
• the second process unit is in the form of a gas-liquid separator and is configured for separating the condensed reaction product obtainable in the first process unit from a residual gas,
• wherein the first process unit comprises a first and a second compartment, wherein said compartments are configured such that
• plate interspaces of the first compartment are traversable from top to bottom by the process gas mixture and
• plate interspaces of the second compartment are traversable from bottom to top by a residual gas dischargeable from the second process unit, as a result of which further reaction product is condensable from the residual gas in the plate interspaces of the second compartment;
• and wherein the interior of the pressure jacket has a drying apparatus arranged therein, wherein the drying apparatus is fluidically connected to the plate interspaces of the second compartment.
