Write 2 page essay on the topic Batch Distillation Column.
A single batch column is able to separate a multi-component mixture in a single operation, to its various components. During the start-up period, the column is adjusted in a way that ensures the distillate produced will be of desired purity (Jana, 2008, 145). The production period is, in contrast, the part of the process during which the product is withdrawn from the column.
Operation of the batch distillation column takes place in four ways. Constant reflux ratio, total reflux, optimal ratio, and constant distillate composition are the methods used in operating batch distillation column. The method of operation of the batch distillation column is dependent on the type of mixture that is being separated. In the separation of the methanol/water mixture for instance, total reflux method could be appropriately used.
In total reflux, the batch process is left alone to approach steady state before the withdrawal of the distillate product is allowed to start. In order to now achieve steady state, overhead vapours are condensed and collected in the condenser-reflux drum system (Diwekar, 2011, 5). All the liquid that has been condensed is directed to return to the column. When this happens, the liquid is further taken through the distillation process several times until there is no more distillate product to be removed. This continuous process of reflux and subsequent distillation ensures that the maximum possible purity is obtained, since no more distillate product is left unremoved.
The process that goes on in the batch distillation column is a complex one. Liquid mixture is put in a vessel that is known as the still spot. The vessel is then heated to such a time as vapour is produced, and the vapour is directed to a rectifying column. As the vapours rise in the column, they become enriched in the component of the mixture that is more volatile. In the initial start-up period, all the vapour collected from the top section of the column is
