Custom Tower Internals Fabricated to Your Drawings
Ambani Metals has been manufacturing distillation column internals for over 25 years, made to your drawings or process data. Our range covers the main distillation column internal parts, including liquid distributors, chimney trays, demister pads and support grids, in stainless steel, duplex and nickel alloys. Each order is dimensionally inspected before it ships, and we export to over 40 countries.
Distillation tower internals are the parts inside a column that put vapor and liquid in contact and then separate them again. They include trays, packing, distributors, collectors, support grids and mist eliminators. Refineries, petrochemical, chemical, pharmaceutical and gas processing plants all rely on them, and they have a direct effect on separation quality, pressure drop and how often the column needs servicing.
Packing only works well if the parts around it are right. A packed bed needs a good liquid distributor at the top, collectors and redistributors between beds, and solid support grids and bed limiters above and below. If any of these is poorly designed, liquid channels through the bed and efficiency falls. For this reason, we prefer to supply the internal parts together for the whole column.
As column internals manufacturers, we begin with your operating data: vapor load, liquid rate, column diameter, pressure and how corrosive the fluid is. From that we suggest the internals that suit your service. Where the design needs it, we trial-assemble the parts in our workshop before dispatch. If you need one replacement part or a full set for a new or revamped column, send us your data sheet or drawings and we'll come back with a design and a quote. Export packing and shipping documents are part of every order.

Custom Distillation Column Internals Design & Fabrication
Ambani Metals manufactures distillation column internals strictly as per client drawings or process data. Our engineering team reviews vapor load, liquid flow, column diameter, operating pressure, and material compatibility before finalizing hydraulic design and mechanical fabrication. Every internal component is shop-fabricated, trial-assembled where required, dimensionally inspected, and packed for global export to ensure seamless site installation.

FAQs
Column internals are components or structures installed inside distillation, absorption, or stripping columns to enhance their performance in separating or purifying chemical components.
Common types of column internals include trays, packing materials (random or structured), liquid distributors, vapor distributors, demister pads, and mist eliminators.
Column internals serve several purposes, including facilitating mass transfer between vapor and liquid phases, providing surface area for contact, promoting even distribution of fluids, preventing channeling or bypassing, and ensuring efficient separation or purification of chemical components.
The design and selection of column internals significantly impact the efficiency, capacity, and reliability of separation processes. Properly chosen internals can improve mass transfer rates, reduce pressure drops, minimize liquid holdup, enhance tray or packing efficiency, and optimize column operation.
Factors to consider include the properties of the fluid mixture being processed, the desired separation efficiency, column diameter and height, operating pressure and temperature, corrosion resistance, fouling tendencies, maintenance requirements, and cost considerations.
Trays are horizontal plates fitted at intervals in the column. They handle high liquid loads, solids and fouling well, and they're easier to clean. Packing is a bed of structured or random elements, and it usually gives lower pressure drop and higher capacity for the same column diameter. It needs a good liquid distributor to work properly. The right choice depends on the service, fouling tendency, loads and allowable pressure drop.
Demister pads and mist eliminators are installed to remove liquid droplets or mist from vapor streams. They typically consist of mesh-like materials that intercept and capture liquid droplets, allowing clean vapor to pass through while preventing liquid carryover. This helps maintain product purity, protect downstream equipment, and comply with environmental regulations.
Yes, column internals can be customized to meet the specific requirements of different applications. This may involve selecting materials with appropriate corrosion resistance, designing trays or packing configurations tailored to the separation process, or incorporating specialized features to address unique challenges.
Yes. Ambani Metals provides detailed fabrication and GA drawings for client approval before production. All column internals are manufactured strictly as per approved drawings or client process data.
Yes. We regularly export distillation column internals to the Middle East, Europe, Africa, Asia, and Pan-Pacific regions, supported by export-grade packing and complete shipping documentation.
Yes. We manufacture complete column internals packages, including trays, distributors, collectors, demisters, support plates, and retainers — engineered as an integrated system for your column diameter and operating conditions.
