Course Description

Gas Absorption is one of the very first Mass Transfer Unit Operations studied in early process engineering. It is very important in several Separation Processes, as it is used extensively in the Chemical industry.

Understanding the concept behind Gas-Gas and Gas-Liquid mass transfer interaction will allow you to understand and model Absorbers, Strippers, Scrubbers, Washers, Bubblers, etc...

We will cover:

• REVIEW: Of Mass Transfer Basics required
• GAS-LIQUID interaction in the molecular level, the two-film theory
• ABSORPTION Theory
• Application of Absorption in the Industry
• Counter-current & Co-current Operation
• Several equipment to carry Gas-Liquid Operations
• Bubble, Spray, Packed and Tray Column equipments
• Solvent Selection
• Design & Operation of Packed Towers
• Pressure drop due to packings
• Design & Operation of Tray Columns
• Single Component Absorption
• Single Component Stripping/Desorption
• Diluted and Concentrated Absorption
• Basics: Multicomponent Absorption
• Software Simulation for Absorption/Stripping Operations (ASPEN PLUS/HYSYS)

Solved-Problem Approach:

All theory is backed with exercises, solved problems, and proposed problems for homework/individual study.

At the end of the Course:

• Understand the mass trasfer concepts behind Gas absorption
• The importance of solvent selection
• Tray Columns - Model, Design & Operation
• The Equilibrium & Operation Lines
• Model Pressure drops in a Column
• Packed Column - Model, Design & Operation
• Verify Basic vs. Advanced systems
