May I ask if formaldehyde can be removed through flashing or stripping? The formaldehyde content is 2-4%; what would it be after flash evaporation or stripping? Can formaldehyde condense?
Formaldehyde tends to decompose and condense at high temperatures, and it is difficult to effectively separate it using physical separation methods such as flashing or stripping. During these processes, formaldehyde may be carried away along with water vapor, but partial condensation or reactions may also occur, making it difficult to predict the exact remaining amount. It is recommended to choose chemical methods that are more suitable for dealing with formaldehyde, or to use specialized equipment for capturing and treating formaldehyde. .
I’m not sure; is pressure swing adsorption or temperature swing adsorption a possibility?
