Combined unit comprising a heat exchanger and a reactor

The component has a plate construction heat transfer EPvice (5) and a reactor (8). The heat transfer EPvice has alternate spaces between its plates (2) for flows of first and second media. The heat transfer EPvice has a tubular outer wall (10) essentially perpendicular to its circular plates and a tubular inner wall (7) enclosing the reactor. The reactor product flows via openings in the inner wall to the flow volumes for one of the two media.
