Claim Text:
1. An apparatus for heat-integrated distillation providing a distillate being a vapor and/or a liquid, said apparatus comprising: a. an evaporation chamber comprising an inlet for a liquid feed comprising at least two liquids with different boiling points, an outlet for a vapor at a low temperature end, and an outlet for remnants at a high temperature end, b. a condensation chamber surrounding the evaporation chamber and divided into a number of at least two consecutive and pressure-tightly separated sections including a first and a last section, where the first condensation section is placed closest to the low temperature end and the last condensation section is placed closest to the high temperature end, each condensation section having an inlet for compressed vapor and an outlet for not condensed vapor, with the optional exception of the last condensation section, and an outlet for condensate from each section, c. at least one heat transmission wall separating the evaporation chamber-pressure-tightly from the condensation chamber, the evaporation chamber having a rotor for spraying or throwing liquid against the heat transmission wall and connected to a motor for rotating said rotor, d. a compressor, having a high and a low pressure side, for each section of the condensation chamber, a first compressor on a low pressure side, or inlet side, connected to the vapor outlet at the low temperature end of the evaporating chamber and on a high pressure side, or outlet side, connected to the inlet to the first section of the condensation chamber, and a second compressor on a low pressure side, or inlet side, connected to the vapor outlet of the first section and on a high pressure side, or outlet side, connected to the inlet to the second section of the condensation chamber, the second section placed consecutive to the first section and proximal to the high temperature end of the evaporation chamber.
