The essence of "managing risks" lies in design philosophy and operational design! Incorporating a sense of security into operations through design.
In the previous session, we introduced the principle of removing metal impurities by converting them into chlorides using a chlorine furnace (chloride volatilization). Today, we will address a common concern: "Isn't it dangerous to flow corrosive and toxic gases like Cl2 and HCl at high temperatures?" Tubular furnaces are readily available and versatile, making them suitable for the new synthesis of small sample sizes. However, there are undeniable "common issues" such as "a small effective heating area, which tends to limit scalability" and "the risk of small cracks in the tubes due to long-term use or thermal shock, increasing the risk of leakage during positive pressure operation." The equation "high temperature × corrosive gas = danger" is intuitively correct. That is why the essence lies in "managing danger" through design philosophy and operational design. The compact chlorine furnace from Thermonik ENG is built with this concept in mind. Design philosophy for safety: 1) Based on negative pressure (reduced pressure) operation, the furnace is equipped with a vacuum system that maintains the internal pressure consistently lower than atmospheric pressure. This suppresses any potential blowout in the event of seal degradation, thereby reducing the risk of Cl2/HCl leakage. *For more details, please download the PDF or feel free to contact us.

2) Corrosion Prevention for Gas Connection Parts Thanks to Thermonik's unique technology, measures have been implemented to make the gas connection parts resistant to corrosion even when Cl2/HCl is flowed at high temperatures (certified to CE, SEMI, and UL standards). *Specific specifications are not disclosed. Ensuring operational peace of mind through design ■ Standard procedures for startup/shutdown (purge sequence, flow rate, residence time) have been established ■ Regular inspection points (piping, seals, instrumentation) have been clarified Since we are dealing with corrosive gases at high temperatures, there is no "zero risk." What is important is to reduce risks through design, visualize them through operation, and prevent them through systems. The Thermonik ENG chlorine furnace is a solution that places "safety first" at its core. Next time, we will delve deeper into the applications so far and "potential uses." For example, can we selectively eliminate "specific metals only" in impurity removal? This idea and the potential for process integration are still in development, and we welcome your ideas. *For more details, please download the PDF or feel free to contact us.
