Vapor Liquid Equilibrium for Engineers

[@robertoandrade8551]

Hello, I would like to know how to calculate the amount of condensate from a volatile organic compound mixture stream that cross a condenser, i would like to know the amount of condensate for each species of the system , I'd be very grateful if you help me.

Here is an example with numbers: kzbin.info/www/bejne/pqnEhZuIZdKEiJY

@@apm Thak you very much!!!

[@travelwithme1467]

hi sir, may i know how did you solve the 2 unknown equations which are V and L

[@apm]

There is help for equation solving at apmonitor.com/che263

[@xintang3755]

Thank you so much!!! APMonitor is soooo helpful!

pro tip: you can watch movies on Flixzone. I've been using it for watching all kinds of movies lately.

[@hannahlambbb]

can you please tell me where you got that table from?

[@apm]

The table at 3:57 is from Wikipedia: en.wikipedia.org/wiki/Henry%27s_law

[@briansullivan2664]

Awesome for passing tests lol. But how in the field do you measure this or has any of our professors actually held a job before.

+Brian Sullivan, I worked 7 years in industry for ExxonMobil and other companies as a consultant. I was coauthor on a patent that heavily uses VLE to improve reactor efficiency: Lawson, K. W., Hedengren, J. D., Smith, L. C., Method for Controlling Bubble Formation in Polymerization Reactors, International Patent WO2012005740, Issued January 12, 2012, United States Patent Application 20130203946, Issued August 8, 2013. VLE and flash calculations are essential for practicing engineers. Simulators help with the calculations but engineers need the fundamentals to better understand the simulator results.

hey prow Is there any videos that contains solving problems of chapter 5 and 6??!

[@apm]

+Yara Alfaqih Yes, check out this link: www.learncheme.com/screencasts/mass-energy-balances/textbook-felder-3rd

1.25 atm divided by 0.163x10^4 atm should be equal to 0.00076687.

[@apm]

Great catch. The error is at 7:17.

Sir I want material in PDF format

[@apm]

Here are the course notes in PDF form: www.et.byu.edu/~tom/classes/273/Classes/

What if only one component is present with water?

[@michaelcaracotsios8211]

You only need to solve a single equation (the Rachford-Rice equation). You can do that with Goalseek in Excel.

Thanks for the suggestion. Here is a link for those who would like to try this approach. See multi-component section: en.m.wikipedia.org/wiki/Flash_evaporation
