Tantalum Columns

tantalum column mersen

Tantalum is the most corrosion resistant metal in common use today. It is inert to practically all organic and inorganic compounds. This reactive metal is inert to Sulfuric and Hydrochloric acid below 150°C. It has good thermal conductivity, is erosion resistant, and forms easily.

Tantalum’s high workability and weldability make it a perfect material of construction for a wide range of equipment such as pressure vessels, columns or reactors.

Tantalum columns design

In 1988, Cometec was established to design and manufacture tantalum process equipment for the most corrosive chemical applications. In 1998, Cometec was acquired by Mersen and was renamed Mersen Linsengericht “home of tantalum” in 2010

A Tantalum column will often be specified for chemical, petrochemical, oil & gas and other severe industrial manufacturing environments. These chemicals are frequently heated to very high temperature so that the material of construction should resist corrosion.

Tantalum columns should be considered for any applications whenever corrosion resistance is a major consideration and when longevity and reliability are required.

Accessories such as dip pipes or columns internals can be also manufactured out of tantalum.

Our 3200 m2 workshop allows the production of very large pieces of tantalum equipment (up to 4.4 meter in width and up to 4.2 meter in height, with a maximum weight of 20 tons).

Mersen offers both loose-lined and explosion-cladded tantalum columns.

Tantalum Dip Pipes

They are used inside the column to:

  • introduce a liquid into a reactor under the filling level.
  • introduce a gas into a reactor, under the filling level, often close to the agitator, for quick gas dispersion; such dip pipes may be bent to the optimal introduction point for a quick dispersion.
  • through short dip pipes, introduce a liquid or a gas into a reactor above the filling level, while preventing the media from coming into contact with the nozzle wall.
  • introduce a liquid into a reactor above the filling level, through a bent dip pipe, in order to direct the flow towards the wall and prevent splashing on the surface.
  • prevent installing an outlet nozzle, for safety reasons, and empty the reactor via a long dip pipe by overpressure in the vessel.
