批次和连续蒸馏之间的差异

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.

什么是批处理蒸馏?

批处理蒸馏是在混合物批处理中分离组件的方法。在这种方法中，通过蒸馏进行分离反复进行。批处理蒸馏很容易进行。该过程给出了分离化学物质的纯度，并且该过程的最大灵活性（单个批处理过程可以处理几种不同的化学物质）。

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
批处理蒸馏是在混合物批处理中分离组件的方法。	连续蒸馏是使用连续过程在混合物中分离组件的方法。
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.
Efficiency
这efficiency of batch distillation process is low compared to the continuous distillation.	这efficiency of the continuous distillation process is very high.
Flexibility
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.

概括– Batchvs Continuous Distillation

蒸馏是通过连续加热和冷却在混合物中分离组件的技术。蒸馏有两种主要形式。批处理蒸馏和连续蒸馏。批处理和连续蒸馏之间的区别在于，批处理蒸馏是分批完成的，而连续蒸馏是作为连续过程进行的。
