Book excerpt: The goal of this work is to propose a multiperiod mixed-integer linear programming model for the design and production planning of multistage multiproduct batch plants integrating, simultaneously, scheduling decisions. The time horizon consists of several periods in which deterministic variations due to seasonal or market fluctuations like prices, products demand limits, costs, and raw materials availability, are taken into account. The plant operates using production campaigns along each time period. The objective function maximizes the net present value considering incomes from product sales and, investment, resources, inventories, operation, waste disposal and late delivery penalties costs. The proposed model allows not only finding the optimal plant structure (unit sizes and its duplication in parallel in each stage), but also the production planning in every time period as well as number and optimal sequence of batches in each campaign.

Book excerpt: Energy optimization and the optimization of water use have mainly been treated as separate problems in literature. The batch production schedules resulting from each of these formulations do not guarantee that the plant is operated optimally. Presented in this contribution is a formulation that addresses the optimization of both water and energy, while simultaneously optimizing the batch process schedule. The scheduling framework used in this study is based on the formulation by . This formulation has been shown to result in a significant reduction of computational time, an improvement of the objective function and leads to fewer time points. The objective is to improve the profitability of the plant by minimizing wastewater generation and utility usage. From a case study it was found that through only applying water integration the cost is reduced by 11.6%, by applying only energy integration the cost is reduced by 29.1% and by applying both energy and water integration the cost is reduced by 34.6%. This indicates that optimising water and energy integration in the same scheduling framework can reduce the operating cost and environmental impact significantly.

Book excerpt: This work presents a novel, efficient and expressive Constraint Programming (CP) approach to the short-term scheduling problem of multistage batch plants. The CP model accounts for many features found in industrial settings and allows modeling operational policies that group batches of the same product into campaigns. Product campaigns simplify the plant operation and allow reducing scrap and changeover times. The formulation has been extensively tested with various examples, including large-scale ones, and different objective functions. Comparisons with results reported in recent contributions are also presented and discussed.

This book was released on 2013-06-10 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scheduling and control problems are traditionally solved sequentially. However, integration of both problems can result in a better overall performance. A main challenge in the integration is the solution to the derived mixed-integer dynamic optimization (MIDO) problem. To overcome the challenge, we present a novel integration method, which simultaneously determines the PI controller design and the scheduling decisions. The method decomposes the MIDO problem. The dynamic optimization for each transition can be solved independently offline. A set of controller candidates are generated and stored. Then the integrated problem is transformed into a mixed-integer nonlinear fractional programming problem of scheduling with controller selection. This problem can be efficiently solved to the global optimaity by the Dinkelbach's algorithm.

This book was released on 2013-06-10 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electricity-intensive process industries are seeking for new ways to achieve savings on energy costs, taking advantage of the liberalization of electrical markets and integration of distributed generation. Also, the increasing share of renewables requires the grid to adapt to varying electricity availability and consumption patterns. Optimal production scheduling of power-intensive steel making processes with regard to energy cost may lead to significant savings in the electricity bill. For the purpose of this research the steel plant melt shop model described in Harjunkoski & Grossmann (2001) has been adopted as a use case. The steel plant is assumed to participate in a day-ahead electricity market with hourly varying electricity prices and to face financial penalties in case the plant’s actual electricity consumption deviates from the committed level. The resulting scheduling problem is formulated as a continuous-time Mixed Integer Linear Programming (MILP) problem, enhanced by introducing energy price-related time slots and tested on realistic production data for various problem sizes. The results show that compared to the standard makespan-driven approaches, the process plant is able to save on operational expenditures while satisfying the critical production rules and due dates.

Available in PDF, EPUB and Kindle. Book excerpt: Batch chemical processes, so often employed in the pharmaceutical and agrochemical fields, differ significantly from standard continuous operations in the emphasis upon time as a critical factor in their synthesis and design. With this inclusive guide to batch chemical processes, the author introduces the reader to key aspects in mathematical modeling of batch processes and presents techniques to overcome the computational complexity in order to yield models that are solvable in near real-time. This book demonstrates how batch processes can be analyzed, synthesized, and designed optimally using proven mathematical formulations. The text effectively demonstrates how water and energy aspects can be incorporated within the scheduling framework that seeks to capture the essence of time. It presents real-life case studies where mathematical modeling of batch plants has been successfully applied.

Available in PDF, EPUB and Kindle. Book excerpt: Batch processes are used to manufacture many fine organic chemicals, and as such they can be considered to underpin much of the modern chemical industry. Despite widespread use and a consequent huge contribution to wealth creation, batch processes have attracted limited attention outside the user industries. Batch chemicals processing uses a number of core techniques and technologies, such as scheduling and sequence control, agitation and batch filtration. The combination of these technologies with often complex chemistry, the multi-purpose nature of much of this type of plant, the distinctive safety and environmental issues, and a fast moving commercial environment makes the development of a successful batch process a considerable challenge for the chemist or engineer. The literature on the topics covered in this book is fragmented and often not easily accessible, so this handbook has been written to address this problem and to bring together design and process analysis methods in the core areas of batch process design. By combining the science and pragmatism required in the development of successful batch processes this new book provides answers to real problems in an accessible and concise way. Written by an international team of authors drawn from industry, consulting and academe, this book is an essential part of the library of any chemist, technologist or engineer working on the development of new or existing batch processes.
