Key Difference – Batchvs Continuous Distillation
批处理蒸馏和连续蒸馏是蒸馏过程的类型。这key differencebetween batch and continuous distillation is that批处理蒸馏以批量进行，而连续蒸馏作为连续过程进行.
Distillation is a chemical technique that is used to separate components in a mixture.

4.Side by Side Comparison – Batch vs Continuous Distillation in Tabular Form
A batch distillation can be done in a single distillation column. There, multiple components can be separated into separate receiver tanks. When distillation of one batch is completed, the column can be used for a completely different component mixture quickly and efficiently. And also, this process can be completely automated.
However, the batch distillation is highly subjected to contamination. That is because, when the column is used for a separate batch after the completion of one distillation, trace amount of the previous batch can be remaining in the system and thus, the following batch can get contaminated (if the following batch is identical to the previous batch, this is not something to be concerned).
What is Continuous Distillation?
连续蒸馏是使用连续过程在混合物中分离组件的方法。这re are no interruptions for this process until the completion of the distillation. This method has high efficiency for separation. The amount of the mixture used for the separation has no limits as for batch distillation.
这continuous distillation is an expensive process when compared with the batch distillation. This technique requires more distillation columns than that of batch distillation; the number of columns required for the continuous distillation is expressed as N-1 whereas N is the number of components separated from the distillation.
What is the Difference Between Batch and Continuous Distillation?
Batch vs Continuous Distillation
|Number of Distillation Columns|
|Batch distillation requires one distillation column.||Continuous distillation requires N-1 columns where N is the number of components needed to be separated.|
|这efficiency of batch distillation process is low compared to the continuous distillation.||这efficiency of the continuous distillation process is very high.|
|Batch distillation is highly flexible because several different components can be separated using a single distillation column.||连续蒸馏的灵活性较小，因为每个组件都使用了几个与混合物分离的蒸馏柱。|
|Changing the Mixture|
|In batch distillation process, after completion of the distillation of a batch, the column can be used for a completely different component mixture quickly and efficiently.||In continuous distillation process, it takes a long time to change the mixture that is being distilled.|
