Industrial Vacuum Distillation Equipment Desired Separation Alternatively Materials

0.5 mbar Vacuity Distillation Column for CBD / THC / Hemp oil

——Particular features

Continuous distillation process.
Low operating pressures (100~10000Pa ,100Pa=1mbar).
Short residence time.
High evaporation rates.
Processing of high-boiling, high-viscosity or crystallizing products is possible.
Can be used as a reboiler for column.
Low fouling on evaporator wall.

Large-scale industrial Distillation Column use reflux to achieve a more complete separation of products. Reflux refers to the portion of the condensed overhead liquid product from a Distillation Column that is returned to the upper part of the tower as shown in the schematic diagram on the right. Inside the tower, the reflux liquid flowing downward provides the cooling needed to condense the vapors flowing upward, thereby increasing the effectiveness of the distillation tower. The more reflux is provided for a given number of theoretical plates, the better the tower's ability to separate lower boiling materials from higher boiling materials. Alternatively, the more reflux provided for a given desired separation, the fewer theoretical plates are required.

In industrial uses, sometimes a packing material is used instead of trays within the Distillation Column, especially when operating under reduced pressures. This packing material can either be random dumped packing (one to three inches wide) such as Raschig rings or structured sheet metal. Liquids tend to wet the surface of the packing and the vapors pass across this wetted surface, where mass transfer takes place. Unlike conventional tray distillation, in which every tray represents a separate point of vapor liquid equilibrium, the vapor liquid equilibrium curve in a packed column is continuous. However, when modeling packed columns, it is useful to compute a number of "theoretical plates" to denote the separation efficiency of the packed column with respect to more traditional trays. Differently shaped packings have different surface areas and void space between packings. Both of these factors affect packing performance.
