Fractional Distillation for the Laboratory and Industry

Home , Fractional distillation, Reflux

ll distillations attempt to separate a lower boiling material (A) from a higher boiling material (B). Packed columns are “packed” A with a material that creates a large surface area within the distillation column. Vapors rise through the column, are condensed by the condenser and fall back down the column. This material is called the condensate. The descending condensate “wets” the packing. Ascending vapors rise through the wet packing and are forced into intimate contact with the condensate. This intimate contact causes the vapor to become enriched in the lower boiling material. This process is often called rectiﬁcation.

It uses a helix rotating at high speeds inside the distillation column. The rotating band forces vapors into intimate contact with the condensate on the wall of the distillation column. This contact takes place in a very thin layer that is refreshed thousands of times per minute. As a result, spinning band distillation gives a very efficient separation in a short distillation column. 9600 High Efficiency Distillation Systems Controller he 9600 is a high efficiency fractional distillation The M690 controller eliminates most of the lab T system designed for challenging separations on technician’s monitoring time from the distillation process. batches of 1 to 500 liters.
