“…Two different SR-REM algorithms were developed at IFPEN: a direct algorithm and an indirect SR-REM algorithm (de Oliveira, 2013;de Oliveira et al, 2013a,c;Hudebine and Verstraete, 2004). The direct SR-REM algorithm (Fig.…”

“…Applying this theory to the composition of petroleum fractions implies that the probabilities in Equation 9 are replaced by the mole fractions x i of the library molecule i. This method, as applied to feedstock reconstruction developed at IFP (Hudebine et al, 2002;Hudebine, 2003;Hudebine and Verstraete, 2004;Van Geem et al, 2007), uses the analytically determined indices as boundary conditions. We consider the global solution of the following nonconvex problem: …”

“…the average molecular weight, specific density...), by formulating model hypotheses and using expert knowledge . Most of the methods used to reconstruct the molecular composition of complex mixtures implement a two-step algorithm (Liguras and Allen, 1989a,b;Neurock et al, 1994;Quann and Jaffe, 1996;Dente et al, 2001;Joo et al, 2001;Hudebine and Verstraete, 2004;Van Geem et al, 2007). In the first step a large set of representative molecules, the so-called library of molecules, is created.…”

“…In order to illustrate this methodology for the feedstock reconstruction, different applications can be proposed such as LCO reconstruction for example [6][7]. In this paper, the reconstruction of various FCC gasolines by entropy maximization is presented.…”

“…They are based on different strategies that depend on the type of feedstocks to rebuild. For the heaviest petroleum fractions (vacuum gas oils, atmospheric residues, vacuum residues), the main approach consists in sampling randomly different statistical distributions of structural blocks which are the basic elements of the molecules present in the mixture after reconstruction [1][2][3][4][5][6][7][8]. For the lightest petroleum cuts (gasolines, kerosenes, gas oils), the majority of the methods is based on a predefined set of compounds which is supposed to be representative of the molecules that are actually present in the fraction under investigation.…”
