Distillation Columns
Distillation Columns
Distillation is one of the most popular separation technique of separating chemical substances depending on differences in their volatilities in a boiling liquid mixture. It is a process in which a mixture of liquid or vapour with two or more substances is separated into its desired purity component fractions by the application and removal of heat. It is usually a part of a larger chemical process and hence also referred to as a unit operation.
S2 Engineering (S2) design, manufacture, assemble, install and commission distillation column's as part of their turnkey process equipment solution supply.
S2's distillation columns are widely used in various industrial applications, especially in gas plants, to make the process of distillation more efficient. Distillation columns are specially designed columns in the shape of a tall metal cylinder internally fitted with perforated horizontal plates to achieve this separation efficiently.
Types of Distillation Column
S2 manufacture both batch and continuous distillation columns, as outlined below.
Batch column: Here the column feed is introduced batch-wise. In other words once the column is charged with a 'batch', the distillation process starts and when one batch is completed, the distillation of the next feed starts.
Continuous column: Continuous columns process on the other hand involves a continuous feed stream. No interruptions occur unless and until there is a problem with the surrounding process units. Continuous column is the most common type of distillation column and can handle high throughput.
