Dissolved oxygen in water

Dissolved oxygen in water

Dissolved oxygen in water

Does anyone have a good chart or table for finding dissolved oxygen in water at various temperatures and pressures. I have found some up to 30 psi and 120 degrees. In particular how much oxygen would be dissolved in water at 320 psi and 420 F.

RE: Dissolved oxygen in water

Henry's law constant for oxygen solubility in water may be found in Perry Chem Engg Handbook - section 2 on physical and chemical data.

In this tabulation, there are no values close to what you would be looking for

at 1atm, 212degF, H = 7e4 atm / (mole fraction O2 in water)
At 79degF, 144psig, H = 5.16e4 atm/ (mole fraction O2 in water)

partial pressure of O2 in vapor phase, atm = H * (mole fraction O2 in water)

In this tabulation, more values in the range you're looking for are stated to be found in the Transactions of the AI Mech E Vol 76, pg 69 - year 1954

RE: Dissolved oxygen in water

Can you provide more information on the application?
