In a packed-bed distillation column, can a thermometer port be installed in the packing section for inserting a thermometer?

I have a question: if a structured packing is used in the packing distillation column, can a thermometer port be installed in the packing layer for inserting a thermometer probe?； Since the sensitive plate of the distillation column is the theoretical plate located below the feed inlet, and it is best for the thermometer to measure the temperature of the liquid phase, I raised the above question and look forward to an answer!
It is possible to set this; in the structural design, the filling height and method, as well as the direction and depth of thermometer insertion, should be taken into consideration
It can be set, but the shape of the structured packing determines that it cannot be inserted too deep; the position of the structured packing must be carefully considered during design
Okay, thank you. I’ll talk to the filler manufacturer at that time
Yes, it’s still necessary to communicate with the filler manufacturer to determine whether it’s better to insert it inside the filler from a technical perspective
For bulk packing, it is also possible to insert thermocouples first and then install the packing. It’s hard to say the same for structured packing – the molds used by manufacturers are fixed, so it’s basically impossible for everything to line up just right so that it fits in perfectly.
The packing in the stripping section below the feed inlet is designed to be divided into two sections; an additional liquid collection and redistribution device is added. However, there is no need to worry anymore about measuring the temperature of the sensitive plate, as the thermometer probe is placed in the liquid collection tank of the liquid collector or redistributor.
Thermometers are generally placed between two layers of packing; they cannot be installed in structured packing
Regular packing materials are drilled using a drill with a serrated bit, in a manner similar to drilling holes in a concrete wall; the metal debris is removed, and then the thermometer is inserted
