Considering a binary system 1,4-epoxybutane and water. They separate into two phases at 14.7 psi and 122°F. Using the two methods, a) Determine the equilibrium composition of each liquid phase. b) Find a graphical solution to part (a) by determining where the Gibbs energy of the system is at a minimum. Attach the plot. c) Using the criterion for inherent instability of a single liquid phase, determine the composition range over which the system is inherently unstable and will spontaneously separate into two phases. d) Following part (c), determine the ranges where the single liquid phase will not necessarily spontaneously separate into two phases. mol The system can be described by two - parameter Margules equation with A = 7400 and B = -1400 mol

Transcribed Image Text:Considering a binary system 1,4-epoxybutane and water. They separate into two phases at
14.7 psi and 122°F. Using the two methods,
a) Determine the equilibrium composition of each liquid phase.
b) Find a graphical solution to part (a) by determining where the Gibbs energy of the system
is at a minimum. Attach the plot.
c) Using the criterion for inherent instability of a single liquid phase, determine the
composition range over which the system is inherently unstable and will spontaneously
separate into two phases.
d) Following part (c), determine the ranges where the single liquid phase will not
necessarily spontaneously separate into two phases.
