Distillation Column

SEDL distillation columns are engineered to maintain minimal pressure drop (low ∆P) across trays or packing. This design ensures smoother vapor flow, avoids flooding and weeping, and enhances energy efficiency. Suitable for both tray (plate) and packed internals, these columns are ideal for vacuum or mild-pressure operations where pressure-sensitive feeds are processed

A distillation column, also known as a fractionating column, is a vertical vessel designed to separate components of a liquid mixture through selective boiling and condensation. It consists of several key components:

  • Column Shell: The main body housing internal components
  • Trays or Packing: Structures that facilitate contact between rising vapors and descending liquids.
  • Reboiler: Heats the liquid mixture to generate vapors.
  • Condenser: Cools and condenses vapors at the top of the column.
  • Reflux Drum: Collects condensed liquid, part of which is returned to the column as reflux.
Sugar Mill Modern

These components work together to achieve efficient separation of mixture components based on their volatilities.

The Distillation Scheme with MVR Based system and easy plant operation is a great option for manufacturing processes that will revolutionise the future of chemical process industry.

We design, fabricate and install variety of distillation columns according to requirements of clients. We provide different configuration of distillation system such as Continuous Distillation Column, Single and Multi-Stage Distillation Column, Azeotropic Distillation Column and Vacuum Distillation Column.

How It Works

The operation of a distillation column is based on the principle of vapor-liquid equilibrium

Step Icon

Feed Introduction

The liquid feed enters mid-column.

Step Icon

Vapor–Liquid Contact

Vapor–Liquid Contact

  • Tray Columns: Vapor rises through perforated trays; liquid flows down via downcomers.
  • Packed Columns: Vapor and liquid flow counter-currently through packing surfaces.

Step Icon

Low ΔP Design

Internals are optimized (e.g., structured packing, openarea trays) to minimize resistance to vapor flow, reducing column pressure drop across stages.

Step Icon

Condensation & Reflux

Vapor is condensed at the top; part returns as reflux to enhance separation.

Step Icon

Product Withdrawal

Distillate is collected at the top and bottoms at the reboiler.

Why IsIt Needed?

Distillation columns are essential for

01

Purification

Removing impurities to obtain pure substances.


02

Fractionation

Separating complex mixtures into useful fractions, such as in crude oil refining.


03

Product Recovery

Recovering valuable components from mixtures.


04

Chemical Synthesis

Providing pure reactants for chemical reactions.


Their ability to handle large-scale separations makes them indispensable in industrial processes.
