Description

Introduction:
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:
You will be able to understand mass transfer mechanism and processes behind Absorption and Stripping. You will be able to continue with a Distillation Theory and more Mass Transfer Unit Operation Course and/or Separation Processes Course.
About your instructor:
I majored in Chemical Engineering with a minor in Industrial Engineering back in 2012.
I worked as a Process Design/Operation Engineer in INEOS Koln, mostly on the petrochemical area relating to naphtha treating. There I designed and modeled several processes relating separation of isopentane/pentane mixtures, catalytic reactors and separation processes such as distillation columns, flash separation devices and transportation of tank-trucks of product.
