Columns, reactors and pressure vessels


Mersen designs and manufactures pressure vessels, columns (including internals and packing) and reactors in graphite, PTFE lined, reactive metals (tantalum, zirconium) and metals (titanium, nickel alloys) compliant with demanding process constraints such as corrosion, high pressure and high temperature.

Our columns are manufactured in accordance with the following international construction codes: ASME, EN13445, CODAP, AD 2000-Merkblatt

Whatever the constraints of your process, we have the solution within our extensive range of materials.


Graphite columns

Graphite columns

GRAPHITE columns offer reliable and corrosion-resistant solutions for the processes in the organic and inorganic chemical industries.

The columns are manufactured with Graphilor® an exclusive impregnated graphite developed by Mersen.

Tantalum columns

Tantalum columns

For decades Mersen has mastered solid, loose lining and clad tantalum fabrication processes. Tantalum  CL-Clad® is Mersen’s patented cladding process. Mersen's tantalum columns are suitable for the HCl stripping at high pressure. They are used in  very corrosive environment such as: Hydrochloric acid, Sulfuric acid, Nitric acid, Strong organic acids, Bromine, Epichlorydrin

Reactive metals columns

Reactive metals columns

Long experience in the design and fabrication of zirconium, titanium and nickel alloys reactive metal equipment

Zirconium is suitable in corrosive environments such as formic acid, strong alkaline solutions, hydrichloric acid, salt solution, organics, acetic acid.

In processing of coke oven gas, titanium columns are required

Fluoropolymer columns

PFTE loose lined columns mersen

Fluoropolymer columns

Armylor® PFTE loose lined columns or pressure vessels combine the corrosion resistance of PTFE and the safety of the seamless lining process together with the mechanical resistance of the steel or stainless steel shell. The PTFE lined vessels and columns are specially designed to comply with high temperature and they resist corrosive processes, such as HCl stripping, defluorination of H3PO4, HF and H2SO4 dilution, HF processing, etc…
