Course Objectives: (numbers in brackets indicate the relationship to engineering program outcomes)

Familiarize students with vapor-liquid equilibrium theory and practice, including Raoults law, vapor fugacity coefficients and liquid activity coefficients (2).  Familiarize students with the theory and practice of various distillation technologies, including flash, batch and continuous distillation (2,4).  Promote lifelong learning skills through individual projects in vapor-liquid equilibrium (6).  Promote effective communication through group design projects requiring written and oral reports (5).
