Firing accompanied by the generation of toxic gas, safety × reproducibility.

In the chemical industry, safe and reproducible firing in reaction processes is essential for quality control and efficient production. Particularly in reactions that generate toxic gases such as ammonia and carbon monoxide, proper exhaust treatment and control of the furnace environment are required. Inadequate firing conditions can lead to reaction failures or the leakage of harmful substances. Our multi-atmosphere furnace is designed for seamless vacuum replacement, atmosphere control, heating, and exhaust detoxification, enabling a safe and highly reproducible reaction process. 【Application Scenarios】 - Chemical reactions involving toxic gases - Reactions requiring precise temperature and atmosphere control - Reaction processes at mass production scale 【Benefits of Implementation】 - Realization of a safe firing environment - Improvement in reaction reproducibility - Increased efficiency in scale-up

Applications/Examples of results

【Regarding such issues】 ■ Increased emissions with scale-up - The generation of NH3 and CO, which was not a concern at small scales like tubular furnaces, has reached a level that cannot be ignored with multi-stage trays and increased batch sizes. ■ Differences in material and seal resistance have been revealed - The gas resistance/corrosion resistance of the heating chamber, crucible, and sealing materials is insufficient, raising concerns about lifespan and reproducibility. *For more detailed information, please download the materials or feel free to contact us.
