<p>Short-path vacuum distillation of a liquid hydrocarbon mixture wherein the liquid trickles, preheated, in an evacuated vessel through a vertical packed vaporization bed (17) with an open configuration in the vicinity of a parallel vertical cooled condensation wall (6), in which process at least a portion of the liquid vaporizes from the vaporization bed and, as distillate, condenses on the condensation wall and is removed.</p> |
