Overview of Column Internals: Specifications, Types, Applications, and How it Works
Column internals are important parts used inside distillation and absorption columns to improve contact between vapor and liquid. At Fourmax, these are made as per ISO 9001 and top global standards like Koch-Glitsch, Sulzer, API, and EN. Moreover, high-quality stainless steel (ASTM A240 / AISI grades) and BIS-approved forgings (IS 12146) are used to ensure strong build, corrosion resistance, and long life. These internals suit column diameters from 300 mm to 3000 mm and are specially designed for smooth fluid flow and low pressure drop. Additionally, they include trays, structured and random packings, liquid distributors, redistributors, and support grids. As a result, they play a key role in improving separation and maintaining stable performance.
What is a Column Internal?
A Column Internal is a vital set of components placed inside distillation or absorption towers to facilitate efficient mass transfer between liquid and gas. These include trays, packings, distributors, and other supporting equipment. Fabricated under ISO 9001 certification, our Column Internals are designed following API/EN best practices and sourced using ASTM A240/AISI grades with BIS-approved materials, ensuring both mechanical and process reliability.

Type of Column Internals
- Trays: Firstly, trays are flat decks inside the column. They allow vapor to pass through small holes or slots. Meanwhile, liquid flows across the tray surface. For instance, there are three common designs: bubble cap trays, sieve trays, and valve trays. Moreover, trays help mix vapor and liquid efficiently to improve separation.
- Structured Packings: Secondly, structured packings are made from corrugated metal or plastic sheets. These sheets form a repeating, three-dimensional pattern. As a result, there is a very high surface area. Consequently, liquid and gas come into better contact. Therefore, structured packings boost mass transfer efficiency significantly.
- Random Packings: Thirdly, random packings come in many shapes, such as Pall rings, Raschig rings, and saddles. In other words, these pieces are not fixed in a pattern. Instead, they are poured randomly into the column. As a result, random packings adapt well to changing load conditions. Additionally, they help distribute vapor and liquid more flexibly.
- Liquid Distributors: Next, liquid distributors spread the incoming liquid evenly over the packed bed. For example, they may use nozzles, troughs, or spray heads. Otherwise, poor distribution can cause channeling. As a result, channeling reduces the column’s efficiency. Hence, a good distributor is essential for uniform flow.
- Support and Hold-Down Grids: Finally, support and hold-down grids are mechanical structures placed below the packing. They hold the packing firmly in place. Moreover, these grids keep packing stable during both operation and shutdown. Without them, the packing could shift or move. Consequently, this would harm the column’s performance.
Application of Column Internals
- Oil & Gas Refineries: Firstly, column internals are used in distillation units. They separate different hydrocarbon fractions effectively. Moreover, internals help maintain good contact between vapor and liquid. Consequently, this improves the purity of petrol, diesel, and other products. Therefore, refineries gain better yield and quality.
- Chemical Processing Plants: Secondly, column internals assist in absorption, stripping, and solvent recovery operations. For instance, tray designs or packings allow chemicals to mix properly. As a result, harmful gases are removed, and valuable solvents are recovered. Hence, plants save cost and reduce environmental impact.
- Pharmaceutical Industry: Thirdly, internals ensure high purity levels in API manufacturing and solvent separation. In other words, trays or packings help remove impurities. Furthermore, this guarantees that medicines meet strict quality standards. Thus, patients receive safe and effective drugs.
- Desalination Units: Next, column internals are applied in thermal desalination columns to support vapor-liquid separation. Specifically, packings or trays help raise steam and separate salt from water. Consequently, fresh water is produced from seawater. Therefore, areas with scarce freshwater benefit greatly.
- Fertilizer Industry: Finally, internals optimize ammonia and urea separation processes in production lines. For example, structured packings allow efficient contact between reactant gases and liquids. Moreover, this leads to better recovery of ammonia and urea. As a result, fertilizer plants run more efficiently and produce high-quality products.
How It Works
Column Internals function by optimizing the distribution of vapor and liquid inside a column, allowing efficient contact between both phases. Distributors ensure even fluid spread, while trays or packings maximize contact surface area. This leads to improved mass transfer, critical in separation, purification, and recovery processes. The result is higher efficiency with lower energy consumption and better throughput.
