In thebubble pointmethod, the pores of the membrane are completely wet with a liquid (phase 1) which is then displaced with air (phase 2). The Young–Laplace equation allows the maximum pore radiusrp,max(m) to be calculated from the value of the transmembrane pressure ΔP(Pa) measured ...
At the bubble-point: (2.6)∑KNFN=∑FN. Any combination of pressure and temperature that produces KN values for the given system which satisfy Equation (2.6) is a bubble-point condition. The liquid stream from any equilibrium separation is at its bubble-point when separated, just as the ...
An equation was derived which gives the value of Δt in terms of the average boiling point t aω and the total pressure π(1) calculated for a bubble point equal to t aω For mixtures containing up to four components, a simple formula was found to give quite satisfactory answers. When...

Assuming the liquid phase is perfectly wetting, the capillary pressure in (3b) is modeled by the Young–Laplace equation, pc=2γr, (10) where γ is the surface tension and r is the radius of the gas bubble. We assume that the gas phase forms as a single bubble in the pore and th...
The bubble/dew point locus in the near-critical region, the critical points and the compressed fluid densities of two ternary mixtures of the methane carbon dioxide-n-butane system were measured in a ROP computer-controlled, mercury-free, high-pressure PVT system. The Soave-Redlich-Kwong (SRK)...

Under this condition, the local pressure at the nozzle outlet equals the local saturated vapor pressure of the working fluid, when the first bubble will be formed inside the nozzle. The second critical condition we define is the point when the vapor phase or the liquid-vapor mixture has ...
