Vijay Gupta, Auteur ; Ignacio E. Grossmann, Auteur |In this paper, we present an efficient strategic/tactical planning model for offshore oilfield development problem that is fairly generic and can be extended to include other complexities. The proposed multiperiod nonconvex MINLP (mixed integer [...]

Jose A. Caballero, Auteur ; Ignacio E. Grossmann, Auteur ; Majid Keyvani, Auteur |Currently the separation of olefins (ethylene, propylene) from (ethane, propane) on a commercial scale is performed almost exclusively by cryogenic distillation in petrochemical industries. Since this technology is highly energy intensive, there[...]

Pedro M. Castro, Auteur ; Ignacio E. Grossmann, Auteur |We propose linear generalized disjunctive programming (GDP) models for the short-term scheduling problem of single stage batch plants with parallel units. Three different concepts of continuous-time representation are explored, immediate and gen[...]

Abdulrahman M. Alattas, Auteur ; Ignacio E. Grossmann, Auteur ; Ignasi Palou-Rivera, Auteur |Production planning modeling is an essential tool in the operation and management of modern refineries. It has traditionally relied on linear programming (LP) principles and methods for simple and robust planning models, such as the fixed-yield [...]

Sebastian Terrazas-Moreno, Auteur ; Ignacio E. Grossmann, Auteur ; John M. Wassick, Auteur |This paper presents a novel mixed-integer linear programming (MILP) formulation for the tank farm operation problem (TFOP), which involves the simultaneous scheduling of continuous multiproduct processing lines and the assignment of dedicated st[...]

Fengqi You, Auteur ; Ignacio E. Grossmann, Auteur |An important challenge for most chemical companies is to simultaneously consider inventory optimization and supply chain network design under demand uncertainty. This leads to a problem that requires integrating a stochastic inventory model with[...]

Vijay Gupta, Auteur ; Ignacio E. Grossmann, Auteur |The main goal of this paper is to extend a simple NPV (net present value) based optimal oilfield development planning model to include complex fiscal rules. In particular, we consider a recently proposed multifield site strategic planning model [...]

Miguel Angel Gutiérrez-Limon, Auteur ; Antonio Flores-Tlacuahuac, Auteur ; Ignacio E. Grossmann, Auteur |A new multiobjective optimization formulation dealing with simultaneous scheduling and control issues in single line processing systems is proposed. Objective functions featuring economic profit and dynamic performance are considered because nor[...]

Fengqi You, Auteur ; Ignacio E. Grossmann, Auteur ; John M. Wassick, Auteur |We propose a multiperiod mixed-integer linear programming (MILP) model for the simultaneous capacity, production, and distribution planning for a multisite system including a number of production sites and markets. Multiple products are produced[...]

Pedro M. Castro, Auteur ; Iiro Harjunkoski, Auteur ; Ignacio E. Grossmann, Auteur |This work addresses the scheduling of continuous plants subject to energy constraints related to time-dependent electricity pricing and availability. Discrete- and continuous-time formulations are presented that can address these issues together[...]

Sylvain Mouret, Auteur ; Ignacio E. Grossmann, Auteur ; Pierre Pestiaux, Auteur |The optimal scheduling of crude-oil operations in refineries has been studied by various groups during the past decade leading to different mixed integer linear programming (MILP) or mixed integer nonlinear programming (MINLP) formulations. This[...]

Pedro M. Castro, Auteur ; Iiro Harjunkoski, Auteur ; Ignacio E. Grossmann, Auteur |This paper presents a new decomposition algorithm for the optimal scheduling of large-scale multiproduct plants containing a large number of orders. Rather than tackling highly complex, full-space problems that cannot be solved in reasonable tim[...]

Elvis Ahmetovic, Auteur ; Mariano Martin, Auteur ; Ignacio E. Grossmann, Auteur |In this paper we study the simultaneous energy and water consumption in the conceptual design of corn-based ethanol plants. A major goal is to reduce the freshwater consumption and wastewater discharge. We consider the corn-based ethanol plant r[...]

Mariano Martin, Auteur ; Elvis Ahmetovic, Auteur ; Ignacio E. Grossmann, Auteur |In this work we address the water consumption optimization of second generation bioethanol production plants from lignocellulosic switchgrass when using thermo-chemical, thermo-biochemical, or biochemical routes considering corn-based ethanol as[...]
