Tantalum Heat Exchangers and condensers

Tantalum bayonet exchangers Mersen

Tantalum is the most corrosion-resistant metal in common use today. It is inert to practically all organic and inorganic compounds. Tantalum’s corrosion resistance is very similar to glass. Tantalum is often used for the manufacture of Dip Tubes, Piping and Overhead Condensers.

Applications of Tantalum should be considered wherever corrosion is a factor and long-term benefits of reduced downtime, increased life expectancy and profitability are important. Tantalum heat exchangers are used in ultra-corrosive and oxidizing applications, for example with concentrated sulfuric acid, nitric acid, free chlorine, or free bromine. They are also widely used as a vapor condensers in in multipurpose fine chemical and pharmaceutical applications.

Mersen Linsengericht is a center of competence dedicated to the design and manufacturing of tantalum process equipment such as heat exchangers, pressure vessels, columns, and custom-made parts. 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).

Tantalum Shell and Tube Heat Exchangers, for vertical or horizontal installation

Shell and tube heat exchangers are the most common type of heat exchanger used in chemical processes. They are well-suited for higher-pressure applications. This type of heat exchanger consists of a shell with a bundle of tubes inside it. One fluid runs through the tubes and another fluid flows over the tubes, to transfer heat between the two fluids. Mersen Tantalum Shell & Tubes Heat Exchangers are designed for condensation inside the tubes.

They can be installed horizontally or vertically.

  • ¾” or 1” Ta2.5W tubes are used. They have nearly 3 times higher mechanical strength than pure Ta tubes, with the identical corrosion resistance.
  • The tube (0.4, 0.5, or 0.76 mm) and the tube sheet (0.5 or 0.76 mm) wall thicknesses are adapted to meet the customers’ requirements in terms of pressure rating and cost.
  • Up to 580 tubes, DN 800, 202 m² heat exchange surface

The Lip Welding design is the standard design for connection of the tubes to the tube sheets. The Flush Mount Welding design reduces the risk of fluid retention and makes for easier cleaning.

Shell and tube Heat Exchanger with twisted tantalum tubes

Heat Exchangers equipped with twisted tantalum tubes are more efficient than conventional Tantalum Shell and Tube Heat Exchangers, when the fluids velocities are low or when the fluids are viscous.

Shell and Tube Heat Exchangers fitted with twisted Tantalum tubes require less heat transfer surface than conventional shell and tube heat exchangers and are therefore more compact and lower cost since they require less Tantalum material.

Tantalum Hairpin Heat Exchangers

Hairpin Heat Exchangers use true counter-current flow. Unlike multi-pass Shell and Tube designs, where correction factors are used to account for inefficiencies resulting from co-current passes, this Hairpin design maximizes temperature differences between shell-side and tube-side fluids

Tantalum Bayonet Heaters

Bayonet Heaters are vertical, often relatively small, liquid evaporators, which use steam as a heating medium. The design typically consisting of a pair of concentric tubes, allows free tube expansion capabilities together with an internal separation volume to prevent entrainment. For optimal results, the tube bundle is completely immersed in the tank and the bayonet is directly exposed to the fluid.

  • up to 290 tubes, DN 1,350, 40 m² heat exchange surface

Tantalum U-bundle Heat Exchangers

Mersen Tantalum U-Bundle Heat Exchangers are designed for condensation inside or outside of the tubes. They are usually installed horizontally.

  • ¾” or 1” Ta2.5W tubes are used. They have nearly 3 times higher mechanical strength than pure Ta tubes, with the identical corrosion resistance.
  • The tube (0.4, 0.5, or 0.76 mm) and the tube sheet (0.5 or 0.76 mm) wall thicknesses are adapted to meet the customers’ requirements in terms of pressure rating and cost.
  • up to 490 tubes, 317 m2 heat exchange surface
