This module provides students with standard methods to solve problems related to a variety of separation processes, including distillation, gas-liquid absorption, liquid-liquid extraction, and evaporation. It explains the theoretical foundations of separation processes and demonstrates problem-solving techniques for simple two-component systems.
Distillation: Revisits vapor-liquid equilibrium for binary systems and explores various binary distillation systems and equipment. Students will learn to calculate the number of stages, column height, and heat transfer in the condenser and reboiler.
Gas Absorption: Covers different types of gas absorption systems, gas-liquid equilibrium, and the two-film theory. The module includes the study of diffusion in stagnant gas and the liquid phase, rate of absorption, and mass transfer coefficients. Students will also design a column, calculating its height, diameter, and required solvent rate.
Liquid-Liquid Extraction: Focuses on the application and types of liquid-liquid extraction, including solvent selection and ternary diagrams. It covers cross-current and counter-current operations, along with calculations for the minimum required solvent.
Evaporation: Explores the application of evaporation in various systems, heat transfer, and boiling point rises for solutions. Students will learn equipment selection, including single or multiple effect arrangements, and how to design evaporator systems to determine required heat transfer areas and steam economy.
