FIELD: machine engineering.
SUBSTANCE: fractionating string is a corrugated pipe rising at an angle to the horizon and which is gradually cooled in natural or forced fashion. The draining devices for condensate, equipped with shut-off valves and thermometers, divide the corrugated pipe into sections, the number of which is not less than the number of required fractions. To increase the reflux ratio, it is permitted to transfer a portion of condensate from the section to one of the lower section for re-distillation. The compactness of the device is achieved by folding the corrugated pipe into a cylindrical or conical spiral.
EFFECT: reduced dimensions and material consumption of the device, reduced cost of fractionation of multicomponent mixtures as a whole.
