Static HP reactor http://www.princeton.edu/cbe/people/faculty/register/group/facilities/hydrog-reactors/
Example high pressure, constant volume reactor procedure Step 4 Step 1 Step 2 Step 3 Add the first gas to an Insert the test metal Add the water solution Close & seal the vessel initial pressure apparatus Pressure fixed V T =2L Gas 1 Open, T&P known Open, T&P known Sealed T&P known 0.5L water + Container holds a 0.5L water + Sealed, T&P known 0.6L corrosion test unit 0.6L 0.6L corrosion test unit ~0.5L water + dissolved gas, corrosion test unit a 0.6L corrosion test unit, ~0.9L headspace (one gas plus H 2 O) Step 7 Step 4 Step 5 Step 6 The vessel is cooled, gas Add the second gas (if Heat the vessel The vessel is kept at T released , autoclave applicable) to a known for a fixed time opened and corrosion pressure measured Pressure fixed Gas 2 Sealed T&P known Sealed and emptied Sealed and Heated to a ~0.5L water + dissolved gases, Heated to a known T. Test metal cleaned, known T for a fixed time 0.6L corrosion test unit, and P is measured weighed and measured P is measured ~0.9L headspace (two Unknown liquid volume, Unknown liquid volume gases plus H 2 O) 0.6L corrosion test unit, containing corrosion product, Unknown headspace volume ~0.6L corrosion test unit Unknown headspace volume
