Milton, would it be possible to sketch briefly the pros and cons of the different EOS's? I finished reading and I'm ready to approve the article. --[[User:Paul Wormer|Paul Wormer]] 12:50, 5 April 2008 (CDT)

:Paul, thanks very much for findimg all those typos and for adding a few bits information as well. I must have read it a dozen times and I still had some typos!! I would still like to wait, at least a week for other editors (if any) who may have comments, before you nominate the article for approval.
:As for a comparison of the EOS's, I tried that when I was writing the article but couldn't come up with anything that I liked. Some are better in certain areas but not as good in certain other areas. So I decided to say no more than the following (in the section on "Modified versions of the van der Waals equation"):
::<font color=green>Perhaps the most commonly used equations of state by engineers working in petroleum refining, petrochemical production,  natural gas processing, cryogenic distillation and related industries are: the Redlich-Kwong equation developed in 1949, the Soave-Redlich-Kwong equation developed in 1972 and the Peng-Robinson equation developed in 1976. Those three equations are essentially modified versions of the van der Waals equation.</font>

Despite the same name, this article was written completely from scratch. Any similarity with the WP article is purely coincidental. - Milton Beychok 21:15, 2 April 2008 (CDT)

Milton, would it be possible to sketch briefly the pros and cons of the different EOS's? I finished reading and I'm ready to approve the article. --Paul Wormer 12:50, 5 April 2008 (CDT)

Paul, thanks very much for findimg all those typos and for adding a few bits information as well. I must have read it a dozen times and I still had some typos!! I would still like to wait, at least a week for other editors (if any) who may have comments, before you nominate the article for approval.
As for a comparison of the EOS's, I tried that when I was writing the article but couldn't come up with anything that I liked. Some are better in certain areas but not as good in certain other areas. So I decided to say no more than the following (in the section on "Modified versions of the van der Waals equation"):
Perhaps the most commonly used equations of state by engineers working in petroleum refining, petrochemical production, natural gas processing, cryogenic distillation and related industries are: the Redlich-Kwong equation developed in 1949, the Soave-Redlich-Kwong equation developed in 1972 and the Peng-Robinson equation developed in 1976. Those three equations are essentially modified versions of the van der Waals equation.
If you have some wording to suggest other the above, I would be pleased to have you send it to me. Milton Beychok 21:15, 5 April 2008 (CDT)
