How to manage a 20% sodium chlorite solution
Thread Content
Recently, due to process-related reasons, the company plans to install two new 10m3 storage tanks, which will contain a 20% sodium hypochlorite solution. I had heard before that sodium chlorite solutions can explode under certain conditions, and chlorine gas may also be produced. I’d like to ask how this should be controlled? What aspects should be paid attention to during daily operations or inspections?
20% is still quite stable. It is sufficient to consider the control parameters from a physical properties perspective, in order to prevent exposure to light and ensure proper sealing of the storage tanks.
This medium has the following characteristics: strong oxidizing properties, strong corrosiveness, high alkalinity; it releases chlorine dioxide or chlorine when in contact with acids, and it has flammability-enhancing properties. Control measures should be developed based on these characteristics.
