(57) Abstract :
Process and apparatus for the separation of a feed mixture into a higher-
b
oiling and a lower boiling fraction in a continuously operated
distillation apparatus comprising at least one inlet pipe for feeding one or more feed mixtures, an outlet means for the lower-boiling
fraction, an outlet means for the higher-boiling fraction and a heating device, in which the distillation apparatus includes at least two
condensation stages, each of a different temperature level, the condensation stages provided upstream in direction of the vapour flow
having a higher temperature level than the downstream condensation stages, separation-effective internals being installed between the
condensation stages, partial condensation taking place in the condensation stages, partial amounts that have not condensed in these
stages being fed to downstream separation-effective internals or condensation stages of lower temperature level and partial amounts
that have condensed being passed via separation-effective internals in direction of the outlet means for the higher-boiling fraction, a
basically vaporous fluid being obtained at the condensation stage of the lowest temperature level, where it partially condenses, the
uncondensed part of the fluid being fed to the outlet means for the lower- boiling fraction and the condensed part being passed to a
section of the distillation apparatus which is upstream of the condensation stage having the lowest temperature level, and the
condensation stage of the lowest temperature level having a temperature of below -40 C.( Fig. 1)
