VLE Calculations: Help and Explanation

Click For Summary
SUMMARY

The discussion centers on the complexities of Vapor-Liquid Equilibrium (VLE) calculations, specifically addressing terms like bubble point and dew point. Participants emphasize the necessity of a solid understanding of thermodynamics before tackling VLE problems. The conversation highlights the confusion surrounding the appropriate equations and unit conversions required for accurate calculations. Overall, a foundational knowledge of thermodynamics is crucial for effectively performing VLE calculations.

PREREQUISITES
  • Understanding of thermodynamics principles
  • Familiarity with VLE concepts such as bubble point and dew point
  • Knowledge of relevant equations for VLE calculations
  • Ability to convert units appropriately in chemical engineering contexts
NEXT STEPS
  • Study the Antoine equation for vapor pressure calculations
  • Learn how to determine bubble point and dew point using phase diagrams
  • Explore the use of Raoult's Law in VLE calculations
  • Investigate software tools for VLE analysis, such as Aspen Plus
USEFUL FOR

Chemical engineering students, process engineers, and anyone involved in thermodynamic analysis or VLE calculations will benefit from this discussion.

Sorry bout putting the question in the form of like a homework problem, just didnt know how to go bout asking what i wanted.

Basically can anyone explain how to do VLE calculations..

So confused with the topic.

Whats bubblepoint and dew mean..

Cheers. Hopefully this post is ok for this forum.

"Basically can anyone explain how to do VLE calculations.. "

You want it in twenty-five words or less? "You're in over your head."

Little more detail? Put down that copy of Perry's, raise your hands, and back slowly away from the book.

This a "self-study" project? State an educational level --- VLE can be a real waste of time if we take for granted you've had thermo (you say "VLE," and that implies some thermo), and find out you haven't.
 
there's an actual question in the homework section, which i can't solve.

I'm confused on which equation to use.. and whether the units need to be changed.. lot of confusion
