ABSTRACT:
A sampling circuit connected directly to the distillation column consists of a primary loop formed by a sampling tube which penetrates into the column in a region of expansion and vaporization and is equipped with means for limiting the velocity of the vapor collected therein and for separating the entrained liquid fraction if necessary. The sampling circuit further comprises a condenser and a filter, the condensate being returned to the column by a circulating pump and a withdrawal of condensate being effected by a secondary loop for supplying an analyzing device in parallel.
