Apparatus for vapourising a medium and separating droplets as well as for condensing the medium

An apparatus for vapourising a vapourisable medium, separating droplets therefrom and condensing the vapourisable medium when vapourized, wherein the apparatus comprises:

• an outer casing that comprises substantially vertical ends and a substantially horizontal cylindrical shell having an inner surface which defines a substantially horizontal interior space between the vertical ends,
• a substantially vertical partition wall that cross-sectionally divides the interior space of the cylindrical shell into separate horizontally oriented fluid-isolated functional spaces comprised of a first horizontally oriented subspace (A) and a second horizontally oriented subspace (B),
• an evaporator plate pack functioning as an evaporator which is arranged inside a lower region of the first horizontally oriented subspace (A) of the cylindrical shell,
• evaporator inlet and outlet connections for leading a heat exchange medium into and out from the evaporator plate pack, respectively,
• a gravitational droplet separator that is arranged inside the first horizontally oriented subspace (A) of the cylindrical shell I above the evaporator plate pack,
• an inlet connection for the vapourisable medium for leading the vapourisable medium into the first horizontally oriented subspace (A) of the cylindrical shell to thereby form a vapourised medium, and an outlet connection for leading the vapourised medium out from an upper region of the first horizontally oriented subspace (A) of the cylindrical shell,
• a condenser plate pack functioning as a condenser which is arranged inside the second horizontally oriented subspace (B) of the cylindrical shell,
• condenser inlet and outlet connections for leading the heat exchange medium into and out from the condenser plate pack, respectively,
• a vapourised medium inlet connection for leading the vapourised medium into the second horizontally oriented subspace (B) of the cylindrical shell, and a condensed medium outlet connection for leading the condensed medium out from the second horizontally oriented subspace (B) of the cylindrical shell.
