Example high pressure, constant volume reactor procedure

Open, T&P known 0.5L water + 0.6L corrosion test unit

Step 2 Add the water solution Step 3 Close & seal the vessel Step 4 Add the first gas to an initial pressure Step 4 Add the second gas (if applicable) to a known pressure Step 5 Heat the vessel Step 6 The vessel is kept at T for a fixed time Step 7 The vessel is cooled, gas released , autoclave

measured

Sealed T&P known 0.5L water + 0.6L corrosion test unit Sealed, 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 Pressure fixed

Sealed and Heated to a known T. P is measured Unknown liquid volume, 0.6L corrosion test unit, Unknown headspace volume

Step 1 Insert the test metal apparatus

Open, T&P known Container holds a 0.6L corrosion test unit Sealed and Heated to a known T for a fixed time P is measured Unknown liquid volume containing corrosion product, ~0.6L corrosion test unit Unknown headspace volume emptied Test metal cleaned, weighed and measured VT=2L
