RETRACTED: Real component substitute mixture in simulation of petrochemical processes

This article has been retracted at the request of the Editor-in-Chief. Please see Elsevier Policy on Article Withdrawal (http://www.elsevier.com/locate/withdrawalpolicy).Reason: This article is a duplicate of a paper that has already been published in the proceeding of the 5th International Chemical Engineering Congress & Exhibition (IChEC 2008) held on 2–5 Jan, 2008 in Kish Island, Iran. One of the conditions of submission of a paper for publication is that authors declare explicitly that the paper is not under consideration for publication elsewhere. As such this article represents a mis-use of the scientific publishing system. The scientific community takes a very strong view on this matter and we apologize to readers of the journal for this article's inclusion.
