Which type of property method (Activity Coefficient or Equation of State) would you employ for each of the following systems?

 

So each system is either EOS or AC method....

 

1.Oil refining: mixtures of alkanes, alkenes and aromatic hydrocarbons.

2. Phenol synthesis: methyl-ethyl-benzene, oxygen gas, sulphuric acid, water, acetone, phenol.

3.Whiskey distillation: water, ethanol, acetaldehyde, acetic acid.

4.Acetic acid manufacture: ethene, oxygen gas, water, acetaldehyde, acetic acid.

5.Biphenyl manufacture: toluene, hydrogen, benzene, methane, biphenyl (two benzene rings).

 

 

 

I don't just wants the answer but how you came to choosing that particular method. Thanks

The software provider should have answers for you. And, you seem to be making demands of your collegues.

Excuse me if I came across bluntly but I'm not making any demands. I simply would like an explanation of there reasoning if someone were to answer the question. The software provider does not have the answer to this.

You ask advice for 5 totally different, and completely unrelated, systems.

 

That gives us the impression that you are trying to let us do your homework exercise.

 

If you like you can post your 5 answers plus explanations, and we will comment whether they are correct or not.

[Ceng67]

So if I were to ask for 5 completely related and similar systems that would make it fine? I'm now regretting even posting this question from all the hassle I've been getting, I thought this was a place you could come to find help, its not like I'm posting a piece of coursework with 20 questions.

 

This question is from a past years test and not homework, I'm trying to learn what to do if this sort of question appears in future test...

My answers plus 5 explanations would not help anyone as I don't know where to begin. I want to understand the steps taken to figure out which method would be preferable but cant find any information to help me and is why I came here.

Ceng67,

 

PingPong gave you a very wise advice, I don't understand why you were so upset.

Google is your best friend, just google it.

 

I should assume that you already have sufficient thermodynamics knowledge to start.

Try this:

After reading the article, please come back with your answer so that we can have constructive discussion.

 

Good luck.
