Distillation system

A distillation system for concentrating a feed liquid, comprising:

• at least one condensation unit and at least one adjacent evaporation unit, each unit being provided by at least one frame element,
• wherein the frame elements of the system are assembled together to form a stack of frame elements,
• wherein each frame element comprises:
• a feed side and an opposite steam side,
• an outer area comprising a plurality of channels including at least one of:
• a feed channel, a concentrate channel, two steam channels, and a distillate channel,
• an inner area which is open, encased by the outer area and limited by the feed side and the opposite steam side,
• a first group of connection notches comprising at least one connection notch arranged on the feed side and connecting some of the channels with the inner area, the first group comprising:
• a feed connection notch connecting a feed channel with the inner area,
• a second group of connection notches arranged on the steam side and connecting others of the channels with the inner area, the second group comprising:
• a first steam connection notch connecting a first steam channel with the inner area,
• a second steam connection notch connecting a second steam channel with the inner area, and
• a distillate connection notch connecting a distillate channel with the inner area, the system further comprises sealing elements configured to connect adjacent frame elements, wherein the sealing elements comprise different sealing types which are formed such that they block different connection notches, wherein
• the inner area of the frame element of the condensation unit is covered with a liquid tight wall on the feed side.
