OBJECTIVE:
To understand the concepts of Multicomponent distillation systems.
UNIT I THERMODYNAMIC PRINCIPLES
Fundamental Thermodynamic principles involved in the calculation of vapor – liquid equilibria and enthalpies of multi component mixtures – Use of multiple equation of state for the calculation of K values – Estimation of the fugacity coefficients for the vapor phase of polar gas mixtures – calculation of liquid – phase activity coefficients.
UNIT II THERMODYNAMIC PROPERTY EVALUATION
Fundamental principles involved in the separation of multi component mixtures – Determination of bubble-point and Dew Point Temperatures for multi component mixtures – equilibrium flash distillation calculations for multi component mixtures – separation of multi component mixtures at total reflux.
UNIT III MINIMUM REFLUX RATIO FOR MCD SYSTEM
General considerations in the design of columns – Column sequencing – Heuristics for column sequencing – Key components – Distributed components – Non-Distributed components – Adjacent keys. Definition of minimum reflux ratio – calculation of Rm for multi component distillation – Underwood method – Colburn method.
UNIT IV VARIOUS METHODS OF MCD COLUMN DESIGN
Theta method of convergence – Kb method and the constant composition method – Application of the Theta method to complex columns and to system of columns – Lewis Matheson method – Stage and reflux requirements – Short cut methods and Simplified graphical procedures.
UNIT V VARIOUS TYPES OF MCD COLUMNS
Design of sieve, bubble cap, valve trays and structured packing columns for multi component distillation – computation of plate efficiencies.
