Improvements in petroleum refinery planning / Omar J. Guerra in Industrial & engineering chemistry research, Vol. 50 N° 23 (Décembre 2011) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 50 N° 23 (Décembre 2011) . - pp.13403–13418 Titre : Improvements in petroleum refinery planning : 1. formulation of process models Type de document : texte imprimé Auteurs : Omar J. Guerra, Auteur ; Galo A. C. Le Roux, Auteur Année de publication : 2012 Article en page(s) : pp.13403–13418 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Petroleum  Refinery  Process  models Résumé : Optimization of the production planning is crucial for the economic success of a petroleum refinery. Nevertheless, it is a difficult task, because of the large scale of the system and the complexity of the processes involved. Part 1 of this series of two papers addresses the formulation of process models for petroleum refinery planning. First, a generic formulation of nonlinear refinery planning model is adopted from the literature. Subsequently, the formulation of nonlinear empirical models for crude distillation units (CDUs) and a fluid catalytic cracking (FCC) unit is addressed. These empirical models were successfully validated using rigorous process simulators. Finally, the results from model validation showed that the accuracy of model predictions is as good as the current empirical process models reported in the literature, while the empirical process models proposed in this work overcome the limitations of both linear and nonlinear empirical models for CDUs and FCC units previously developed by other authors. Part 2 [Ind. Eng. Chem. Res.2011, DOI: 10.1021/ie200304v] involves the implementation of nonlinear empirical process models in the petroleum refinery planning.

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 50 N° 23 (Décembre 2011) . - pp. 13419-13426 Titre : Improvements in petroleum refinery planning : 2. case studies Type de document : texte imprimé Auteurs : Omar J. Guerra, Auteur ; Galo A. C. Le Roux, Auteur Année de publication : 2012 Article en page(s) : pp. 13419-13426 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Planning  Refinery  Petroleum Résumé : This paper is the second part of a series of two papers on the recent advances in petroleum refinery planning. In Part 1 (Guerra and Le Roux, Ind. Eng. Chem. Res. 2011, DOI: 10.1021/ie200303m), nonlinear empirical process models for CDUs and a FCC unit were developed. The implementation of these models in two case studies for petroleum refinery planning is presented in this paper. In the first case, the empirical model for CDUs was implemented in the planning model for a small-scale refinery. In the second case, the empirical models for CDUs and a FCC unit were integrated in the planning model for a medium-scale refinery. In both case studies, empirical process models from the literature were adopted for refinery processes that were not considered in Part 1 of this work. In addition, a comparison of the computational performance for three popular nonlinear programming (NLP) solvers is presented in case study 1. The case studies showed that the empirical models developed in Part 1 of this work are computationally adequate for the petroleum refinery planning.
