A distillation column is an equipment that separates a chemical mixture into its fractions, based on the difference in boiling points & volatilities. Distillation columns widely used in different industries for various applications.
In distillation process the components that have lower boiling points or are more volatile will be richer in vapor phase of a boiling mixture. Hence, the liquid phase will contain the less volatile material. The efficiency of a distillation column highly depends on the boiling points. If the difference in boiling points between two substances is great, complete separation may be easily achieved by a single stage, otherwise more than one stage is required.
Different types of high efficiency distillation columns are manufactured by Niroonamad Company.
Principally, different modes of distillation columns are based on the same operating principal. However, there are many kinds of distillation columns such as batch & continuous. Batch distillation is an un-steady state operation that typically used in small scale. It must be noted the feed to the column is introduced batch-wise. Firstly, the column is charged with a ‘batch’ and then after achieving the desired goal, a next batch of feed enters the column. Oppose to batch distillation, continuous distillation is a process in which a mixture is continuously fed into the column.
