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.

Who this course is for:

  • Chemical Engineers refreshing their Mass Transfer and Separation Processes course
  • Students on the relevant fields (chemical, mechanical, process engineering)
  • Teachers / Professors requiring extra knowledge on Mass Transfer
  • Engineers working with Absorbers / Strippers or Scrubbers / Washing Gases
  • Stack Gas Engineers

Hi there, I'm Emmanuel Ortega, aka Chemical Engineering Guy...

I've been in the Chemical Industry for about 3 years. I love applying all my knowledge learned in University to the Daily Engineering Life. From working in a Petrochemical Plant as a Process Plant Designer to working with textile material from Polyester Yarns; I could teach you a lot of how it is important to learn the Engineering subjects!

My expertise:

  • Chemical Process Design
  • Plant Design
  • Heat Transfer Operations and Equipment Design
  • Industrial Polyester Yarn
  • Online Tutoring

Right now I'm preparing online material for Engineers all over the world. I have a dream in which online education will break all barriers and let Engineers all over the world learn easier and faster! Please join me in my quest!

The Courses I design are entirely dynamic. You will see theory and then apply it ASAP to a real life problem! I even use the books you are using right now in your engineering courses...

Hope to see you in any of the Courses I'm offering!
