I want to use Cl2 and HCl, but I'm concerned about safety—this small chlorine furnace addresses such on-site issues.

"I would like to consider treatment using Cl2 and HCl, but I have concerns about safety." "I want to reduce the waste liquid and drying processes of wet treatment and remove metal impurities in a dry manner." In response to such on-site challenges, our company proposes a compact chlorine furnace compatible with Cl2/HCl. The compact chlorine furnace can be applied to dry processes that remove trace impurities in oxides and metals as volatile chlorides, halogen cleaning, surface treatment, and material evaluation in corrosive gas atmospheres. With our unique design, we consider the use of Cl2/HCl gas in the mid-temperature range, which is prone to leaks, and can develop a furnace structure that takes into account safe operation, including corrosion-resistant construction, negative pressure operation, gas detection, emergency shutdown, and connection to a scrubbing system. 【Common Concerns】 ■ Wet treatment has heavy waste liquid processing, drying processes, and energy costs. ■ Products are water-sensitive, so I want to avoid wet treatment. ■ I want to selectively remove metal impurities in a dry atmosphere. ■ I want to use corrosive gases, but I am concerned about leaks, removal, and safety measures. ■ I want to compare Cl2/HCl treatment conditions with small samples. *For more details, please download the materials or contact us.
