Fluoropolymer lined columns PTFE Loose Lined Column Armylor ® Columns are manufactured in PTFE lined carbon steel. They are specially designed to comply with high temperature and to resist to corrosive environment. The PTFE liners are made by paste extrusion. PTFE lining is loose, thick and fully resistant to corrosion. For diameter up to 64’’ S •  eamless liners S •  tandard or heavy duty PTFE thickness (up to 10 mm) F •  ine powders of PTFE Focus Application: Stripping HCl It is a system designed to produce HCl gas from a feed of hydrochloric acid solution, usually 33%. T he HCl solution...

Tantalum Columns The High-End Solution We offer tantalum columns made by loose lining or CL-Clad ® process. Tantalum CL-Clad ® plates as well as zirconium and titanium, are exclusively produced in Mersen France and can be shipped to our American or Chinese plants for final manufacturing. To learn more about CL-Clad ® technology CL-Clad ® is a patented cladding process developed by Mersen (France). With this process, a thin layer of reactive metal (Tantalum, Titanium, Zirconium) can be cladded onto a carbon steel or stainless steel base plate. CL-Clad ® technology is perfectly suitable for...

Zirconium Columns Zirconium columns are suitable in corrosive environments, notably for the production of acetic acid where Mersen is recognized as the number 1 in supplying zirconium columns and produces zirconium shell and tube heat exchangers and pressure vessels for the major producers of acetic acid. A long expertise in the design and fabrication of reactive metal equipment combined with an international material sourcing policy allow Mersen to bring quality and cost-effective solutions. Mersen has mastered solid or cladded Zirconium fabrication processes for decades. Mersen has...

Titanium Columns Mersen manufactures titanium columns (solid or clad) in its Chinese, French and American manufacturing sites. Mersen has a long experience in producing titanium columns, notably with a capability up to 7 m diameter. To learn more about titanium Titanium's resistance to the corrosive effect of salt water is among the best available. It is particularly resistant to metallic salts, chlorides, hydroxides, nitric and chromic acids. Different grades of titanium are available (pure and alloys). They can be selected based on corrosion requirements. Focus Application: PTA PTA...
