A heat exchanger plant for distillation comprises at least two parallel process lines (1) with at least two successive heat exchanger stages (2a, 2b), which each comprises a plate package of heat exchanger plates provided in such a way that first plate interspaces for condensation and second plate interspaces for evaporation are formed. The heat exchanger stages form rows (8) with heat exchanger stages which lie after each other and transversely to the process lines. Each heat exchanger stage is adapted to perform condensation of steam and evaporation of a liquid, wherein they are supplied with steam to the first plate interspaces and a liquid to the second plate interspaces. The supplied steam is condensed to a liquid and the supplied liquid is evaporated and supplied to the first plate interspaces in the next heat exchanger stage for evaporation of a liquid supplied to the second plate interspaces in this next heat exchanger stage. The plant comprises a closed casing (10), which encloses an inner space (11) in which the process lines are provided. The casing has, seen in a cross-section transversely to the process lines, a rectangular shape. |
