Guess T 4. y T y i i = 6. if y T > 1, T if y T < 1, T 8. Bubble T and y i found 5. y T = 1? Yes No 3. y i = x i γ i P i sat = x i K i P 1. Know x i , P. Guess T (e.g. eq 9.62). 2. Adjust T until P calc = P P calc x 1 γ 1 P 1 x 2 γ 2 P 2 + = 3. Bubble T found, y i = x i γ i P i sat = x i K i P 1. Know y i , T Calc P i sat . Assume Raoult’s law for first P , x i cal- culation, then calc γ i at x i . 4. x i changed? Yes for first loop pass. 2. P 1 y i γ i P i ------------- i ---------------------- = 5. Calc γ i at new x i 6. Dew P and x i found
