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).
