For an ideal gas, (1.2)PV=nRT where P= pressure V= volume n= amount of gas, mole R= gas constant T= absolute temperature If pressure is in psi, volume in ft3, and T in Rankins, the value of R is 10.73. The ideal gas law can be rearranged as (1.3)PVT=nR=C If the amount ...
\(r\)the mean radius of curvature of the liquid/gas interface (proportional to pore radius),Rthe universal gas constant, andTthe absolute isothermal temperature. Generally, smaller\(r\)values enable a lowerPvto condense gas molecules at a given temperature (Fig.1)20,21,22. For example, ...

Equation 6-106 is the radial diffusivity equation for compressible fluids. This differential equation relates the real gas pseudopressure (real gas potential) to the time t and the radius r. Al-Hussainy, Ramey, and Crawford (1966) pointed out that in gas well testing analysis, the constant-...
Figure 4. Equilibrium constant for reaction (11) In addition to the bulk phase reaction with H2S the ZnO also has some activity for reaction (9), COS hydrolysis, and for reaction (10), the shift reaction. Absorption of H2S will cause the COS hydrolysis (9) to proceed to full conversion...
