This situation leads to alarms firing, emergency shutdown or even accidents. In order to avoid these consequences an analysis of both the process and the control system must be performed. However, the complexity of both systems together with their interactions makes this analysis a hard task. The D-higraph functional modeling methodology is presented, this technique integrates functional and structural information of the plant. In this paper D-higraphs is used to reconfigure the control system of a process plant under faulty situations, which means improving system's robustness and autonomy.

Book excerpt: This study seeks to pave the way of designing and implementing a Domain-Specific Language (DSL) for controllability analysis of a chemical process design. Chemical processes are nonlinear continuous/discrete dynamic systems that are subject to considerable uncertainties and variations during their design and operation. These systems are designed to operate at an economically optimal steady-state. However, changing the value of the process parameters may cause deviations and elicit dynamic responses from processes. Generally, the ability of holding a process within a specified operating regime is called controllability. In this study a Petri net based DSL is designed specifically for controllability evaluation of process designs with an application to a flowsheet case study.

Book excerpt: Product transfer is a problem commonly encountered in industry when a production has to be transferred from a source plant to a target plant. In this paper a strategy to assist product transfer is proposed. The strategy is based on latent variable models (LVMs) to relate the data available from one or more source plants with the (usually scarce) data available from the target plant, and on LVM inversion to estimate the target plant operating conditions. The inversion is performed within an optimization framework, which can handle constraints for both product quality variables and input variables. An experimental nanoparticle production process is used as a test bed to illustrate the benefits of the proposed strategy.

Book excerpt: In this work we present a mathematical optimization based methodology for simultaneous formulae and process design in the consumer product business applied to the case of laundry detergents. The design of a new detergent is formulated as a modified pooling problem including process, performance, processability and environmental constraints. This features add a number of nonlinearities related to the modeling of the different aspects of the process and customer acceptance. Furthermore, the problem becomes a multiobjective optimization problem, when environmental constraints are considered, that is solved using the e-constraint method with global optimization techniques to minimize of the environmental impact while minimizing the production cost for a couple of case studies. Finally, ingredients price uncertainty is also addressed using a scenario reduction technique.

This book was released on 2013-06-10 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reliable models for rate-based phenomena are the backbone of model-based process design. These models are often unknown in the early design phase and need to be determined from laboratory experiments. Although model-based experimental analysis and process design are often executed sequentially, the kinetic models might not be suitable to reliably design a process. In this paper, we address this problem and present a first step on the integration of model identification and process optimization. Rather than decoupling model identification and process optimization, we use information from process optimization to design optimal experiments for improving the quality of the kinetic model given the intended use of the model. Sensitivities, which describe the influence of parametric uncertainties on the economic objective used in process optimization, are used as weights for optimal experimental design. This way, the confidence in the parameter values is maximized to reduce their influence on the process optimization objective. This first step on the integration of model identification and process optimization improves the predictive quality of a reaction kinetic model for process design without any further experimental effort.

Book excerpt: The formulation of Enterprise-Wide Optimization (EWO) problems as mixed integer nonlinear programming requires collecting, consolidating and systematizing large amount of data, coming from different sources and specific to different disciplines. In this manuscript, a generic and flexible data structure for efficient formulation of enterprise-wide optimization problems is presented. Through the integration of the described data structure in our synthesis and design framework, the problem formulation workflow is automated in a software tool, reducing time and resources needed to formulate large problems, while ensuring at the same time data consistency and quality at the application stage.

Book excerpt: This contribution follows the earlier work by on the optimization of a comprehensive power plant utility system, a system consisting of a boiler and a cooling tower. Unlike previous research on the power plant utility system which had focused on the boiler and cooling water systems in a discrete manner, the authors presented a holistic method of analysis and treatment of the combined utility system. In this work further details of the nonlinear comprehensive system model are presented and the objective is maximizing the net revenue from operating the utility system, which is the difference between the total operating costs and the proceeds from the sale of electricity. The work has shown that up to 8 % increase in revenue is achieved when the process is optimized as a single utility system.

Book excerpt: In this paper, we introduce robust optimization and stochastic programming strategies for addressing demand uncertainty in steelmaking continuous casting operations. Robust optimization framework was first employed to develop a deterministic robust counterpart optimization model and to guarantee that the production schedule be feasible for the varying demands. Then, a two-stage scenario based stochastic programming framework was studied for the scheduling of steelmaking and continuous operations under demand uncertainty. To make the resulting stochastic programming problem computationally tractable, a scenario reduction method has been applied to reduce the number of scenarios to a small set of representative realizations. Results from both the robust optimization and stochastic programming methods demonstrate robustness under demand uncertainty and the robust solution is slightly better than the stochastic solution.

Book excerpt: Process engineering applications often lead to non-smooth constrained optimization problems in which the objective function and/or the constraints have non-differentiabilities and step discontinuities. Since the objective function is often the outcome of a complex simulation or the outcome of a lower level optimization problem, it may also be noisy and not defined in some point. In this work we propose and test a new hybrid direct search method for constrained non-smooth discontinuous problems which combines the positive features of Particle Swarm, Generating Set Search, and Complex, that we refer to as PGS-COM. Computational results show that PGS-COM outperforms the main available methods and exhibits considerable robustness to non-smoothness, unrelaxable constraints, evaluation failures and numerical noise.

Book excerpt: The design of efficient supply chains is a major challenge for companies in the process industry. Supply chain performance is subject to different sources of uncertainty including reliability of the facilities. Facility disruptions are among the most critical events that supply chains can experience. In order to reduce the undesirable effects of disruptions, these events must be anticipated at the design phase of the supply chain. This work addresses the design of supply chains under the risk of facility disruptions by simultaneously considering decisions on the facility location and the inventory management. The proposed formulation is based on a two-stage stochastic programming framework where the scenarios are determined by the possible combinations of facility disruptions. The first stage decisions include the location of distribution centers and their storage capacity. The second stage decisions involve assigning customer demands to the distribution centers that are available in every scenario. The objective is to minimize the sum of investment cost and the expected cost of distribution during a finite time horizon. The formulation is implemented and compared with the optimal solution of the deterministic design problem though an illustrative example. The results show that the proposed formulation generates supply chain designs with the capability to adjust to adverse scenarios. This flexibility translates into significant savings when disruptions occur in the operation of supply chains.
