Small chlorine furnace <Impurity separation by selective volatilization of metal chlorides>
Impurities are chlorinated with chlorine/hydrochloric acid! They preferentially volatilize with vapor pressure differences and step temperatures.
The "small chlorine furnace" is a product that simplifies post-processing with dry separation and low contamination while leaving the base material intact and eliminating the need for cleaning. It converts metallic impurities in the material into volatile chlorides through selective chlorination using Cl2/HCl, and preferentially removes them through controlled temperature stages and residence times in a dry process. Additionally, by utilizing the vapor pressure difference and Gibbs free energy difference of metal chlorides, it can achieve high selectivity in separation without compromising the composition or crystalline phase of the base material, resulting in minimal wastewater discharge and reduced environmental impact and costs. 【Features】 ■ Selectivity: Utilizes the vapor pressure difference of chlorides to preferentially volatilize only target impurities. ■ Staged temperature profile: Sequential separation from low to medium temperature, minimizing damage to the base material. ■ Dry and low waste: Almost zero wastewater with no cleaning required, simplifying post-processing. *For more details, please download the PDF or feel free to contact us.
