Available in PDF, EPUB and Kindle. Book excerpt: Model and adjoint equations of this formulation form a two-point boundary value problem that interfaces with an efficient optimization strategy. Decisions representing network structure, reactor type and the amount of heat addition are made through continuous parameters in the model. The method is therefore fairly general and can be applied to large kinetic mechanisms with almost any objective function. Literature examples are presented and solved in order to demonstrate the effectiveness of this approach."

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "The reactor is the most influential unit operation in many chemical processes. Reaction systems and reactor design often determine the character of the flowsheet. However, research in reactor network synthesis has met with limited success because of nonlinear reaction models, uncertain rate laws, and numerous possible reactor types and networks. In this paper we take advantage of attainable region properties derived from geometric targeting techniques to design a concise reactor modules [sic] for reactor network synthesis. The reactor module is made up of a continuous stirred tank reactor (CSTR) and a plug flow reactor (PFR) (for two dimensional targeting) or a differential sidestream reactors (DSR) (for higher dimensions). These modules are used to synthesize the optimal reactor network target with respect to a specific objective function and the problem is formulated as a compact MINLP. This new algorithm overcomes many of the drawbacks of existing algorithms. Finally, we solve several example problems to illustrate the feasibility of the proposed algorithm and discuss applications to simultaneous reactor network and process synthesis."

Available in PDF, EPUB and Kindle. Book excerpt: We develop optimization-based approaches for reactor network synthesis suitable for simultaneous process synthesis. We propose reactor network models that consider additional degrees of freedom in terms of the number and composition of inlet and outlet streams, and candidate sets of reactions that can be (de)activated in different reactors. These features provide flexibility to the models, allowing a rich connectivity of the reactor network with other subsystems (e.g., separation and heat exchanger networks) and the formulation of new problems for reactor network synthesis during the early stages of chemical process design. Accordingly, we propose a generalized superstructure-based framework for reactor network synthesis that allows seamless coupling with approaches for separation network synthesis. The candidate reactions are modeled through tasks assigned to reactors. We develop a graph theoretic approach to systematically build the reactor network superstructure. First, we represent the reactions and tasks through multiple graphs and identify competition among tasks with similar roles. Second, we propose integer optimization models based on task competition to determine the number of candidate reactors and interconnecting streams required in the superstructure. Finally, we formulate and solve the optimization model for the integrated synthesis problem. Furthermore, we propose modeling methods that allow us to account for costs in attainable region-based approaches for reactor-separation network synthesis. This approach allows us to determine the bounds of productivity (targets) of a desired component achievable by any reactor-separation network, for a given reaction system and feed stream. We holistically analyze cost trade-offs within the attainable region as well as provide a method to obtain practical targets to be used as benchmarks. We accurately identify the attainable region using the continuous stirred tank reactor (CSTR) equivalence principle and introduce separation models accounting for costs to perform the required separation tasks. Finally, we show how some subregions, typically close to the attainable region boundary, are expensive to achieve.

Book excerpt: "The new 4th edition of Seider’s 'Product and Process Design Principles : Synthesis, Analysis and Design' covers content for process design courses in the chemical engineering curriculum, showing how process design and product design are inter-linked and why studying the two is important for modern applications. A principal objective of this new edition is to describe modern strategies for the design of chemical products and processes, with an emphasis on a systematic approach. This fourth edition presents two parallel tracks : (1) product design ("what to make"), and (2) process design ("how to make"), with an emphasis on process design. Process design instructors can show easily how product designs lead to new chemical processes. Alternatively, product design can be taught in a separate course subsequent to the process design course."--adapted from description on publisher web site.

This book was released on 2013-12-01 with total page 2410 pages. Available in PDF, EPUB and Kindle. Book excerpt: Combinatorial (or discrete) optimization is one of the most active fields in the interface of operations research, computer science, and applied math ematics. Combinatorial optimization problems arise in various applications, including communications network design, VLSI design, machine vision, air line crew scheduling, corporate planning, computer-aided design and man ufacturing, database query design, cellular telephone frequency assignment, constraint directed reasoning, and computational biology. Furthermore, combinatorial optimization problems occur in many diverse areas such as linear and integer programming, graph theory, artificial intelligence, and number theory. All these problems, when formulated mathematically as the minimization or maximization of a certain function defined on some domain, have a commonality of discreteness. Historically, combinatorial optimization starts with linear programming. Linear programming has an entire range of important applications including production planning and distribution, personnel assignment, finance, alloca tion of economic resources, circuit simulation, and control systems. Leonid Kantorovich and Tjalling Koopmans received the Nobel Prize (1975) for their work on the optimal allocation of resources. Two important discover ies, the ellipsoid method (1979) and interior point approaches (1984) both provide polynomial time algorithms for linear programming. These algo rithms have had a profound effect in combinatorial optimization. Many polynomial-time solvable combinatorial optimization problems are special cases of linear programming (e.g. matching and maximum flow). In addi tion, linear programming relaxations are often the basis for many approxi mation algorithms for solving NP-hard problems (e.g. dual heuristics).

Download or read book State of the Art in Global Optimization written by Christodoulos A. Floudas and published by Springer Science & Business Media. This book was released on 2013-12-01 with total page 638 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optimization problems abound in most fields of science, engineering, and tech nology. In many of these problems it is necessary to compute the global optimum (or a good approximation) of a multivariable function. The variables that define the function to be optimized can be continuous and/or discrete and, in addition, many times satisfy certain constraints. Global optimization problems belong to the complexity class of NP-hard prob lems. Such problems are very difficult to solve. Traditional descent optimization algorithms based on local information are not adequate for solving these problems. In most cases of practical interest the number of local optima increases, on the aver age, exponentially with the size of the problem (number of variables). Furthermore, most of the traditional approaches fail to escape from a local optimum in order to continue the search for the global solution. Global optimization has received a lot of attention in the past ten years, due to the success of new algorithms for solving large classes of problems from diverse areas such as engineering design and control, computational chemistry and biology, structural optimization, computer science, operations research, and economics. This book contains refereed invited papers presented at the conference on "State of the Art in Global Optimization: Computational Methods and Applications" held at Princeton University, April 28-30, 1995. The conference presented current re search on global optimization and related applications in science and engineering.
