Regarding data regression
Thread Content
Binary interaction parameters can be regressed using gas-liquid equilibrium data. So now that we only know the phase equilibrium constant k=f(t,p) and have no experimental data, can regression be performed?
For the ternary system of carbon dioxide, carbon monoxide, and methanol, it is known that the formula for the gas-liquid equilibrium constant of carbon dioxide in methanol within the mixture is a function of pressure and temperature…
Based on k=f(t,p), when x, t, and p are known, y can be calculated. In this way, a large amount of x, t, p, y data can be obtained, and this is the experimental data.
