What are the barrier to run a process at 600bar 1700C
What are the barrier to run a process at 600bar 1700C
(OP)
I was simulating an acqueous reaction (Na2SO4+H2O<=>2NaOH+SO2)
and got a maximum rate at 600bar 1700C.
What are potential physical (not economical) limitations that could prevent the design/development of such a process.
The final product has to be cooled down to 200C.
Thank you all for your suggestions and contributions.

600 bar is also very high, even at relatively normal pressures.
Definelty bespoke items.

Also, if there was ever a reason to do heat capture, you have it.

...but how you transport...?
The molten material could be transported using a refractory line pipe

The steel shell of the lined pipe will be exposed to about 500C. It should be able to handle 600bars without issue.

How to find a catalyst to use?
Still unclear on how to cool and depressurize the final product...

Can you consider options like Compositepro mentioned? This seems to be a very difficult way to make some caustic.

Getting heat in and out would seem to be quite difficult also.

You can have high pressure simultaneous with high temperature ONLY if the source of the high temperature is internal to the process. But even in that case, such extremes of simultaneous P and T are only done when they are absolutely necessary. Generally, very hot processes aren't also done at high pressure, and very high pressure processes are done at much more modest temperatures.
Refractory lined pipe relies on separating the heat from the pressure retaining boundary by means of the refractory insulation. The pipe remains cold to resist the pressure. But there are always losses across the insulation, and the pipe itself must dissipate all that heat leakage to avoid getting hot itself.

jari001 (Chemical) you are right but I know more expensive process than this one to make caustic.
