Pls anyone tell the formula.. and the effect of pressure created inside the autoclave during reaction on the particle shape and size. Pls explain.
If the container is completely filled, i guess you could just use the steam table to relate pressure to Boiling point of water.
Hydrothermal processing involves heating aqueous slurries of biomass or organic wastes at elevated pressures to produce an energy carrier with increased energy density and is essentially similar to how the earth has produced fossil fuels over millions of years.
There are several methods to calculate or better estimate it.
The pressure gauge can be installed in Autoclave either inlet lines or inside reactor. the pressure gauge may be digital or spring loaded.

I am also trying to work this out and have read everything attached but not really gotten anywhere. If the inner container is 60% filled with a solution containing 3%wt PVA and 3%wt TiO2 xerogel, and I want to heat the solution to 150deg C for 3 hours in an autoclave, how would I work out what temperature the oven should be set to? Consider that the autoclave has no pressure gauge? Seems to me that the accepted pressure / temperature relationships keep sending me in circles...
I am trying to work out time evolution of hydrostatic pressure within the teflon reactor inside an autoclave so that the hydrostatic pressure does not exceed the designed safety pressure of an autoclave (3MP).
Any idea or lead on how to determine this mathematically?
We can assume a certain filling volution at the beginning (e.g., 30%) and a starting temperature (e.g., 150C).
