We specialize in the design, fabrication, and supply of Distillation Columns for a wide range of Distillery, chemical, petrochemical, and refinery applications.
Our columns are engineered to ensure optimum mass transfer efficiency, low pressure drop, and long-term mechanical reliability.
We offer Packed, Tray, and Bubble Cap Type Columns, designed in accordance with international design codes and tailored to meet client process requirements.

Types of Distillation Columns

1️⃣ Packed Column

Used for continuous and batch distillation, absorption, or stripping services where low pressure drop and high efficiency are required.

• Suitable for vacuum and low-pressure operations
• Options for Random Packing (Raschig rings, Pall rings, Berl saddles) and Structured Packing (Mellapak, Flexipac, etc.)
• High mass transfer surface area and uniform liquid–vapor distribution
• Typically used in chemical, solvent recovery, and gas absorption applications

2️⃣ Tray Column

Designed for moderate pressure and wide operating ranges.

• Available in Sieve, Valve, and Bubble Cap tray configurations
• Optimized liquid hold-up and vapor handling capacity
• Easy maintenance and tray replacement access
• Commonly used in refinery and petrochemical fractionation services

3️⃣ Bubble Cap Column

Used where precise vapor–liquid contact and wide turndown ratio are required.

• Each tray consists of bubble caps that allow controlled vapor flow through liquid
• Ensures stable operation even at varying load conditions
• Ideal for fine separation processes and corrosive or fouling duties.

Design & Engineering

• Tray efficiency evaluation (Murphree / Overall efficiency)
• Packing selection and HETP (Height Equivalent to Theoretical Plate) estimation
• Pressure drop, liquid distribution, and flooding analysis
• Thermal rating and optimization using software tools like Aspen Plus / ChemCAD
• Mechanical design as per ASME Section VIII Div.1, IS 2825, PD 5500, EN 13445
