BATCH FRACTIONAL DISTILLATION UNIT
FUNCTION

To fractionally distil multi-component mixtures under atmospheric pressure as well as under reduced pressures with high efficiency.

CAPACITY

50 Ltrs. To 5000 Ltrs. Reboiler with 5 to 30 theoretical stages.

SALIENT FEATURES

The reboiler is provided with a mechanical agitator to accomplish uniform boil up of the mixture without localized heating and hence avoiding thermal shocks. Controlled heating facility ensures fairly uniform boil-up rates and avoids over heating. Highly efficient structured packing provides a low HETP and low-pressure drop across the column. The unique reflux distribution system with control panel and adjustable program ensures high efficiency of separation. The design of condenser ensures low- pressure drop across it. The appropriate design of the subcooler ensures the entire material to be subcooled to the desired temperature before it is withdrawn. The vacating facility provided ensures easy removal of the distillate without disturbing the vacuum of the system . The vacuum manifold provides a unique feature where the column can be switched over to any vacuum pump at any time. Adequate vapour traps provided to ensure complete trapping of the uncondensed vapours thereby preventing the vapurs from entering the vacuum pumps. The entire column and assembly is provided with specially machined flanges, appropriates gaskets and leak proof accessories to ensure almost zero leaks.

Batch Columns

In batch operation, the feed to the column is introduced batch wise. That is the column is charged with a batch and then the distillation process is carried out. When the desired task is achieved, a next batch of feed is introduced.

Continuous Columns

In Contrast, continuous columns process a continuous feed stream. No interruptions occur un there is a problem with the column or surrounding process units. They are capable of handling high throughputs and are the most common of the two types. We shall concentrate only on this class of columns. The vertical shell houses the column internals and together with the condense & reboiler constitute a distillation column. Separation of components from a liquid mixture via distillation depends on the differences in boiling points of the individual components. Also, depending on the concentrations of the components present, the liquid mixture will have different boiling point characteristics depends on the vapour pressure characteristics of liquid mixtures.
