When handling corrosive medias like hot acids, heat transfer can be a difficult task. It is tricky to find a heat exchanger that is corrosion resistant, efficient and cost effective. Tantaline, a producer of tantalum surface alloys for hot acid environments, recently announced the introduction of a tantalum alloyed heat exchange unit to cover this need.
According to the company this new product is the industry's first welded plate and frame heat exchange designed specifically for hot acids and corrosive chemicals. Previously, acids and corrosive applications had primarily used shell and tube designs, which have limitations with heat transfer efficiency. Tantaline's product features a fully-welded tantalum surface alloyed plate and frame design, thus providing efficiencies five to seven times higher than shell and tube heat exchangers, the company says.
"Acids used in all kinds of industrial processes are most aggressive when they are heated. Heat exchangers, the main product used to heat these acids, have long been a sore point within the industry," said Dean Gambale, president of Tantaline. "Now there is an innovative product that addresses this need and gives the end-user a perfect combination of valuable properties and innovative engineering. Manufacturers and engineers now have a new option for heat exchangers without the need to compromise cost or performance."
The gasket less heat exchangers are produced by heating and reacting pure tantalum metal to produce a gaseous atmosphere of tantalum. The vapor creates an alloy bond into the heat exchanger surface. Following this process, Tantaline's heat exchangers have the same chemical properties and corrosion resistance as pure tantalum units, offering significantly higher corrosion performance compared to Hastelloy B, C, and D alloy grades, titanium and zirconium devices.
