High Pressure-Constant
Volume Reactor Calculations
in OLI Studio Analyzer
Static HP reactor http://www.princeton.edu/cbe/people/faculty/register/group/facilities/hydrog-reactors/
Example high pressure, constant
volume reactor procedure
Open, T&P known0.5L water +
0.6L corrosion test unit
Step 2Add the water solution
Step 3Close & seal the vessel
Step 4Add the first gas to an
initial pressure
Step 4 Add the second gas (if applicable) to a known
pressure
Step 5Heat the vessel
Step 6The vessel is kept at T
for a fixed time
Step 7The vessel is cooled, gas
released , autoclave opened and corrosion
measured
Sealed T&P known0.5L water +
0.6L corrosion test unitSealed, T&P known
~0.5L water + dissolved gas,a 0.6L corrosion test unit,
~0.9L headspace (one gas plus H2O)
Gas 1
Pressure fixed
Sealed T&P known~0.5L water + dissolved gases,0.6L corrosion test unit, and
~0.9L headspace (two gases plus H2O)
Gas 2
