WebOct 29, 2024 · Flash calculations for a benzene–toluene mixture with z 1 = 0.3 = 30 mol% benzene in the vapour. At the bubble point (98 °C) all is liquid. At the dew point (104 °C) all is vapor. Feed composition: 30 mol% benzene ( z = 0.3 molfr.). The vapour fraction at 100 °C has to be calculated: t = 100 °C. WebThe critical point lies at the intersection of the bubble and dew-point curves, and no longer serves to identify where the single phase region begins. With most reservoir systems it is normal to concentrate only on the liquid-gas equilibrium behavior, although some hydrocarbons do exhibit solid phases, such as wax precipitation (solid-liquid ...
