A disjunctive programming model for simultaneous synthesis and detailed design of cooling networks / José María Ponce-Ortega in Industrial & engineering chemistry research, Vol. 48 N° 6 (Mars 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N° 6 (Mars 2009) . - pp. 2991–3003 Titre : A disjunctive programming model for simultaneous synthesis and detailed design of cooling networks Type de document : texte imprimé Auteurs : José María Ponce-Ortega, Auteur ; Medardo Serna-González, Auteur ; Arturo Jimenez-Gutierrez, Auteur Année de publication : 2009 Article en page(s) : pp. 2991–3003 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Cooling  networks  Disjunctive  programming  formulation  Optimum  cooling  network  configuration  Mechanical  design  Thermal-hydraulic  variables Résumé : This paper presents a model that simultaneously considers synthesis and detailed design aspects of cooling networks. The model is based on a generalized disjunctive programming formulation that is transformed into a mixed-integer nonlinear program. The objective function is to minimize the total annual cost, which accounts for the cold utility consumption cost, the capital cost for the coolers and pumps, and the pumping costs. The model uses a stagewise superstructure that allows combinations of cooler arrangements in series or in parallel, as well as bypass, mixing, and splitting of the cold utility. The model also incorporates several constraints to meet some specified design codes. In addition to the optimum cooling network configuration, the solution provides the details on the mechanical design features and thermal−hydraulic variables of each cooler unit. Three example problems are presented to show the application of the proposed model.

Facility location and supply chain optimization for a biorefinery / Ian M. Bowling in Industrial & engineering chemistry research, Vol. 50 N° 10 (Mai 2011) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 50 N° 10 (Mai 2011) . - pp. 6276-6286 Titre : Facility location and supply chain optimization for a biorefinery Type de document : texte imprimé Auteurs : Ian M. Bowling, Auteur ; José María Ponce-Ortega, Auteur ; Mahmoud M. El-Halwagi, Auteur Année de publication : 2011 Article en page(s) : pp. 6276-6286 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Optimization Résumé : This paper presents a systematic approach for the optimal production planning and facility placement of a biorefinery. A structural representation is first developed to include sources of biomass feedstock, distributed preprocessing hubs, and centralized processing facilities to produce desired products and byproducts. An optimization formulation is developed to determine the optimal supply chain, size, operational strategies, and location of the biorefinery and preprocessing hub facilities. The model considers simultaneously the optimal selection of different configurations considering the specific location configuration (centralized and/or distributed), selection of biomass, and processing facilities to determine the one with the maximum overall net profit. The objective function considers the overall sales and the costs for the feedstocks, transportation costs, capital costs for the facilities, and the operational costs for the facilities. The model also considers nonlinear economy-of-scale behavior of the capital-cost functions that are reformulated using disjunctive models to yield convex relationships to guarantee a global optimal solution. The proposed model was applied to two case studies.

Integration of renewable energy with industrial absorption refrigeration systems / José María Ponce-Ortega in Industrial & engineering chemistry research, Vol. 50 N° 16 (Août 2011) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 50 N° 16 (Août 2011) . - pp. 9667–9684 Titre : Integration of renewable energy with industrial absorption refrigeration systems : systematic design and operation with technical, economic, and environmental objectives Type de document : texte imprimé Auteurs : José María Ponce-Ortega, Auteur ; Eman A. Tora, Auteur ; J. Betzabe Gonzalez-Campos, Auteur Année de publication : 2011 Article en page(s) : pp. 9667–9684 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Design  Refrigeration Résumé : This paper presents a new methodology for the energy integration of systems that require refrigeration. It considers the integration between process streams as well as that between the heat from process stream excess, solar energy, fossil fuels, and biofuels to run the stripper required by the absorption refrigeration (AR) needed. The proposed methodology consists of two stages: the first one identifies the energy targets, while the second one uses a new mathematical programming model to solve a multiobjective optimization mixed-integer linear programming (MILP) problem, allowing one to determine the minimum cost as well as the minimum greenhouse gas emissions (GHGE) to satisfy the utility requirements identified in the first stage. The proposed model considers the optimal selection of different types of solar collectors, and since the solar radiation depends on the season of the year, the model also accounts for the best combination of fossil and biofuels to complement the energy required for the AR. The proposed methodology is very useful to identify the scenario required to implement the use of clean energies in the refrigeration process. Three problems are presented to show the applicability of the proposed methodology, which does not exhibit numerical complications; these results show that process integration helps to get a given reduction in the GHGE economically attractive involving the use of dean energies, besides identifying the required tax credit to get economic and environmentally efficient cooling systems. In addition, because of the availability of the solar radiation, the solar collectors must be integrated with different types of energy, depending on the season of the year.

Betzabe Gonzalez-Campos, Auteur ; José María Ponce-Ortega, Auteur Année de publication : 2011 Article en page(s) : pp. 8558-8570 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Biomass  Planning Résumé : This paper presents a multiobjective optimization model based on a mathematical programming formulation for the optimal planning of a biorefinery, considering the optimal selection of feedstock, processing technology, and a set of products. The multiobjective optimization problem simultaneously considers the profit maximization and the environmental impact minimization. The economic objective function takes into account the availability of bioresources, processing limits, and demand of products, as well as the costs of feedstocks, products, and processing routes. On the other hand, the environmental assessment includes the overall environmental impact measured through the eco-indicator-99 based on the life cycle analysis methodology. The proposed methodology generates a Pareto curve that identifies the set of optimal solutions for both objectives, and it is applied to a case study for planning the production of a biorefinery in Mexico.

Synthesis of heat exchanger networks with optimal placement of multiple utilities / José María Ponce-Ortega in Industrial & engineering chemistry research, Vol. 49 N° 6 (Mars 2010) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 49 N° 6 (Mars 2010) . - pp. 2849–2856 Titre : Synthesis of heat exchanger networks with optimal placement of multiple utilities Type de document : texte imprimé Auteurs : José María Ponce-Ortega, Auteur ; Medardo Serna-González, Auteur ; Arturo Jimenez-Gutierrez, Auteur Année de publication : 2010 Article en page(s) : pp. 2849–2856 Note générale : Industrial Chemistry Langues : Anglais (eng) Mots-clés : Heat  exchanger;  Networks;  Synthesis;  Utilities Résumé : The synthesis problem of optimal heat exchanger networks using multiple utilities is addressed. A mixed integer nonlinear programming (MINLP) model is developed based on a stagewise superstructure that contains all possible matches between hot and cold streams in every stage. Unlike previous MINLP formulations, exchanges of process streams with utilities are allowed in each stage of the superstructure to determine the optimal location of hot and cold utilities. The optimal choice of different types of available utilities is considered through a disjunctive programming formulation. The model can handle forbidden matches and required and restricted matches as well as isothermal and nonisothermal process streams. The MINLP problem is readily solved using commercial local solvers. Four examples are presented to show the application of the proposed methodology. No computation complications were observed in the examples presented, and they required small CPU times.
