The reaction requires a temperature of 175 degrees Celsius, in the absence of a steam source. What heating medium can be used?
Heat transfer oil, molten salts, or direct electric heating can help you with the design
For smaller systems, electric heating can be used; for larger systems, heat transfer oil is a better option
What are the problems with using electric heating in large systems?
What are the differences in their scope of application?
General-purpose heat transfer oil: stable and safe.

The disadvantage is that the heating process is slow; for intermittent systems, it takes longer to reach the desired temperature when starting from a low temperature. Compared to electric heating, there are also costs associated with the maintenance and replacement of oil. Electric heating is faster, but temperature control can be difficult, especially in processes that require precise temperature control. I’ve not used lava heating before, but it seems suitable for applications such as waste heat utilization and recovery of electricity during off-peak times. For a process with such low temperatures and a small system, there’s no need to consider lava
Okay, thank you! Excuse me, what about using pressurized water?
175°C is a very high temperature for water; it’s not that dry at that temperature
