Industrial Distillation Columns

Product Details:

Pleiad manufactures technically advanced Tray and Packed Type distillation columns with Sieve, Bubble cap and Valve trays, and random as well as structured packing.

A Distillation Column works on the principle of distillation, which is the process of separating two or more liquids, having different boiling points (relative volatility), from a mixture / solution. Though this process might sound simple, the different organic liquids involved in the process, can cause complications, and hence require careful consideration while designing the distillation column. This requires thorough knowledge of the compounds involved and their dynamics under the influence of temperature & pressure. The team at PLEIAD, with its decades of experience have gained a comprehensive grasp on the compounds and their dynamics.

Typically, a distillation column includes a vertical cylinder, which can be separated into three different sections –

• A Reboiler (heat exchanger) at the bottom
• A column with trays and weirs / packing in the middle
• A condenser at the top

The liquid with solvents is fed in middle and reflux at top of the column. A Reboiler is used to supply heat at bottom and produce vapours that are let into the column. Vapours travel up the column where they come in contact with descending liquid and enrichment of solvents in vapours takes place as they travel up the column.

Vapours get condensed in primary & secondary condenser. Part of condensate is refluxed and balance is taken out as distillate. The raffinate is taken out from bottom.

Key Features:

• Properly designed stripping and rectification section
• Understanding of proper reflux required to achieve solvent removal
• Appropriate sizing for multi-component mixture to meet user requirements
• Proper selection & sizing of reboiler, Adequate automation as per process requirement
• Material of construction as per the nature of volatiles present
• Additional glass window for manual checking

• Solvent recovery
• Solvent removal for COD reduction
• Aroma recovery 
• SOG and NCG removal
