Propose a detailed algorithm like Figure and Table 4.4 for a flash where the percent vaporized and the flash pressure are to be specified.

Start F, z fixed P, T of equilibrium phases fixed Initial estimate of x, y Composition loop Calculate Estimate K = f\x, y, T, P} K-values Iteratively calculate y New estimate of x and y if not direct iteration Calculate x and y Compare estimated and calculated Converged Not values of x and y converged
