What instruments can be used to measure the foam level during chemical reactions?
Thread Content
In batch reactions, as we know, foam is generally generated during the reaction process. So, are there any instruments that can measure the level of this foam, that is, to determine where the foam is at? Are there any instruments capable of measuring that?
I don’t seem to have heard of it; I can only judge by sight.
Consult the manufacturer to see if the radar level gauge is available
An appropriate defoamer can be added, and then it’s easier to choose a level gauge; radars are also affected by foam
Please describe the process; what are the temperature and pressure? What medium? Is the reaction intense? Is there a mixer? Only in this way will the corresponding instrument type be determined~
Continuous feeding is used; foam is generated during the reaction, and it is a quite intense reaction. It’s difficult to find a point for control. The rise in the level of the foam is being used to try to regulate the intensity of the reaction. Conditions: atmospheric pressure, 85 degrees Celsius, ethyl acetate, GBL, etc.; a stirrer is available
It’s fine; ethyl acetate and stainless steel are sufficient to handle it. I’ll give you the materials later.
The esterification reaction requires strict temperature control; an antifoaming agent should be used to regulate the temperature, otherwise it may cause material overflow
I haven’t heard of such a watch; it doesn’t seem easy to measure foam
I haven’t heard of such a gauge; is it possible to make improvements to the equipment? For example, on the reaction tank, add several overflow ports, and then control and monitor the foam level at those overflow ports
Capacitive level switches, with applications for foam detection. Consult the manufacturer directly for details.
