What is Gas Absorption? (Lec041)

COURSE LINK:
www.chemicalengineeringguy.co...
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
- Solvent Selection
- 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)

Beautifully Explained !

[@ChemicalEngineeringGuy]

Thanks! Glad you liked it!!

[@JanethMLopez-sp6hz]

I love it!

[@nuramelia4766]

omg thank you so muchh i now understand it well!!!

[@ChemicalEngineeringGuy]

I'm so happy!!

[@justinnicholson9784]

Great teacher

[@ChemicalEngineeringGuy]

Thank you! 😃

[@SanjayYadav-fy4dg]

Please describe the packed column steam stripper column sizing for removal of highly COD solutes from effluent water

[@ChemicalEngineeringGuy]

Will do soon!

[@marisolisoken8944]

Hi great video, do u have more videos on gas absorption

[@ChemicalEngineeringGuy]

yes, please check out the playlist, or go directly to the course: courses.chemicalengineeringguy.com/p/gas-absorption-stripping-in-chemical-engineering

[@sandipkc58]

Is there any specific ratio by which gas and liquid be transferred into absorber?
Also, if the inlet stream pressure and the absorber operating pressure are different, does it create some problem?

[@ChemicalEngineeringGuy]

depends on the equilibrium line! some gases will readily be soluble, and some will not, also depends on T, P

[@imxortal]

Does gas absorbtion in a flash increase it's overall mass?

[@ChemicalEngineeringGuy]

gas absorption is carried out in multiple stages (columns) whereas flash is carried in a single stage. These are two different mass transfer processes. Gas Abs = solubility phenomena. Flash = volatility phenomena

[@TheBeastLyf]

Increase in water flow rate also increases rate of CO2 absorption?

[@ChemicalEngineeringGuy]

generally speaking, yes... More liquid to absorb, will make CO2 from air go to water

[@TheBeastLyf]

Thank you.. but what affects rate of absorption?
