Formaldehyde reactor
Thread Content
Reactor medium: formaldehyde ； What material should be used when the temperature is 100 and the pressure is 1MPa? Please give guidance.
:lol Since it's called a reactor, it doesn't just have formaldehyde.
I agree with what was said above, there must be some other medium, and the parameters given are not very clear.
Let’s first look at the parameters provided. At least it must be made of 304 or above material and the wall thickness should be above 6mm.
Just use 304. 5-6mm
The selection of materials for containers in the chemical industry is mainly based on the following two points:: The composition of the medium and the operating temperature. After these two points are determined, check the "Corrosion Data and Material Selection Manual" to select materials.
Formaldehyde is easily soluble in water and volatile, and is a highly hazardous medium.； What is the concentration, what does it react with, and what is the volume of the reactor? This equipment should belong to the third category of equipment. The material selection depends on the specific medium, so be careful!
The material selection for equipment is mainly based on the physical properties of the material. The wall thickness needs to be calculated. Moreover, if it is a reactor, it will basically have a stirring device. Both strength and stiffness need to be considered.
