Economic needs as well as ecological demands are major driving forces in improving chemical processes and plants. To meet these goals processes have to be intensified in order to get products of higher quality, to increase yield by reducing or even suppressing by-products and to minimise energy consumption. A preferred principle for such intensifications is process - tegration, especially integration of reaction and separation operations. S- entific research in this field has been boosted by certain extremely succe- ful examples like the Eastman-Kodak process for methyl acetate or the MTBE process which are milestones for this method. In 2002 the German Research Foundation defined process integration as one of the major - search topics for the next decade. In 1998 the Department of Biochemical- and Chemical Engineering at the University of Dortmund decided to pool its activities for concerted - forts in process integration and to form a joint research cluster. Our interest was to find out the general challenges as well as obstacles of integrated processes and to work out methods for their design and valuation. Soon it became clear that theoretical work only cannot give reasonable answers.

This book is among the first to address the novel process intensification technologies for biodiesel production, in particular the integrated reactive separations. It provides a comprehensive overview illustrated with many industrially relevant examples of novel reactive separation processes used in the production of biodiesel (e.g. fatty acid alkyl esters): reactive distillation, reactive absorption, reactive extraction, membrane reactors, and centrifugal contact separators. Readers will also learn about the working principles, design and control of integrated processes, while also getting a relevant and modern overview of the process intensification opportunities for biodiesel synthesis. Biodiesel is a biodegradable and renewable fuel that currently enjoys much attention. In spite of the recent advances, the existing biodiesel processes still suffer from problems associated with the use of homogeneous catalysts (e.g. salt waste streams) and the key limitations imposed by the chemical reaction equilibrium, thus leading to severe economic and environmental penalties. The integration of reaction and separation into one operating unit overcomes equilibrium limitations and provides key benefits such as low capital investment and operating costs. Many of these processes can be further enhanced by heat-integration and powered by heterogeneous catalysts, to eliminate all conventional catalyst related operations, using the raw materials efficiently and the reaction volume, while offering high conversion and selectivity, and significant energy savings. The targeted audience of this book includes both academia (students and researchers) and industry (project leaders, technology managers, researchers, biodiesel producers, and equipment suppliers).

Process Intensification of Reactive Separation Networks Through Large Scale Optimization

Process Intensification of Reactive Separation Networks Through Large Scale Optimization

The chemical industry has historically favored increasingly larger plant designs to lower production costs for bulk chemicals and petrochemical products. The drawbacks of scale-up chemical plants, such as the growth in emissions and by-products treatment, have become more relevant due to tighter environmental regulations and more expensive energy resources. Process intensification (PI) is based on the search for radical improvements in chemical processing, substantially decreasing equipment volume, energy consumption or waste formation. Most of the developments in process intensification are based on experimental work while the development of a systematic approach for process intensification is still in its incipient stages. This dissertation proposes to address this problem by applying the IDEAS framework as a systematic tool for process intensification. The search for intensified solutions in chemical processes using nonlinear models can drive a nonlinear synthesis process to stop in one of the multiple local optimal solutions. In the IDEAS approach, nonlinear chemical processes are linearized through the induction of an infinite number of states, forming a convex system that has a guaranteed global optimum. IDEAS based formulations generate an infinite linear program (ILP) which has its infimum value approximated by a series of finite-dimensional linear programs of ever increasing size. Reactive distillation systems are natural candidates for process intensification due to the prompt removal of the product from the reaction by the separation process, usually leading to higher conversion, smaller processing systems, and reduced volumetric footprint. The rigorous identification of the intensification limits for ternary reactive distillation systems through the application of the IDEAS framework is presented in chapter 1, featuring the tradeoff between the system's total capacity (a surrogate for size) and its total reactive holdup (a surrogate for catalyst use). In chapter 2, the tradeoff between the network size, captured by the total capacity variable, and the total utility consumption in a ternary reactive distillation system is investigated. The irreversibilities of reactive distillation systems are investigated in chapter 3 through the solution of the minimum entropy generation rate problem, and its relation to the capacity is assessed. In chapter 4, the potential benefits related to the use of multi-pressure reactive distillation systems are investigated for a ternary azeotropic mixture. The application of the IDEAS approach in problems involving a higher dimensionality in investigated in chapter 5 with the support of a column generation procedure, applied to solve the large-scale linear programming resulted in the assessment of the reactive separation of quaternary azeotropic mixtures.

As a result of fossil fuels-based energy production, reducing atmospheric carbon dioxide emissions has become an urgent issue. Especially, carbon capture and storage (CCS) technology, being one of the leading processes to reduce total carbon emissions, has become increasingly important. Hydrogen is an important energy carrier, and hydrogen-based technologies have increased in importance recently due to the worldwide focus on green processes. The Integrated Gasification Combined Cycle (IGCC) is a promising technology supplying clean energy at affordable prices. The IGCC process is currently being coupled with CCS technologies. However, using CCS technologies in power generation processes is a great challenge, necessitating the intensification of the coupled IGCC-CCS process. Process intensification (PI), leads to substantially smaller, cleaner, and more energy efficient processes, and is a prominent topic, receiving significant attention in recent years. As part of intensifying a process, integration of multiple operations (e.g., reaction and separation) in a single unit is often carried out, to improve the existing process efficiency, and to reduce energy consumption, and unwanted output/by-product generation. The objective of this work is to demonstrate the process intensification potential of a technology, containing one or more water gas shift (WGS) reactor components seamlessly integrated with other plant components. We investigate the applicability of various (alternative to the conventional process) novel and efficient reactor configurations that include self-standing adsorptive reactor (AR)/membrane reactor (MR), and the combination of a MR-LTSR-AR-adsorptive separator (AS)-membrane separation (MS) units (herein after referred to as the LTSR-MS/LTSR-AS/AS-LTSR-AS/MR-AS/AS-MR-AS/MR-AR systems). The proposed WGS reactor technologies have the potential to generate highly efficient and ultra-compact processes, by producing H2 for use in IGCC with simultaneous CO2 capture. Innovative designs of the proposed processes are determined based on the comprehensive modeling and design of the selected IGCC plant's section. Comprehensive, multi-scale, multi-phase, computational fluid dynamics (CFD) models are developed for reaction/separation processes. Developed models quantify the many complex physicochemical phenomena occurring within the process, thus providing the basis to better understand, and intensify the overall system. Model predictions are generated for a broad range of operating conditions and design parameters, thus enabling a comparative performance assessment of the proposed process versus a conventional process for the proposed IGCC application.

In a reactive distillation column, both the chemical conversion and the distillative separation of the product mixture are carried out simultaneously. Through this integrative strategy, chemical equilibrium limitations can be overcome, higher selectivities can be achieved and heat of reaction can be directly used for distillation. Increased process efficiency and reduction of investments and operational costs are the direct results of this approach. Highly renowned international experts from both industry and academia review the state-of-the-art and the future directions in application, design, analysis and control of Reactive Distillation processes. Part I surveys various industrial applications and covers both established large scale processes as well as new chemical reaction schemes with high future potential. Part II provides the vital details for analysis of reactive phase equilibria, and discusses the importance of chemical reaction kinetics, while Part III focuses on identifying feasible column configurations and designing their internal structure. Analysis and control of the complex dynamic and steady-state behavior of reactive distillation processes are described in Part IV. Reactive Distillation - a very promising alternative to conventional reaction-distillation flow schemes.

This book describes the current state of the art in the retrofit of existing distillation processes using advanced distillation techniques. Highlighting concept and practical application rather than theory, it emphasizes the use of advanced process integration and intensification techniques, such as multi-effect distillation, heat pump assisted distillation, thermally coupled distillation, dividing wall column, reactive distillation, and innovative hybrid systems. As a thermal separation method, distillation is one of the most important and widely used technologies in the chemical process industry. While it has many advantages, one major drawback is its large energy requirement, which can significantly influence overall plant profitability. The increasing cost of energy has forced industry to reduce its energy requirement, but simultaneously there has been a need to increase capacity and output due to heightened demand. To accomplish this, the retrofit of distillation processes to increase efficiency and output has become a crucial issue. This book describes the use of advanced process integration and process intensification techniques to carry out effective distillation retrofit. Written by leading researchers in distillation process, process integration, process intensification, and process retrofit, the book presents a comprehensive review of contemporary advanced distillation techniques which can be employed in grass-root systems and retrofit. It is a valuable source of information for undergraduate and postgraduate students of chemical engineering, practicing process designers and chemical engineers.

Separation and purification processes play a critical role in biorefineries and their optimal selection, design and operation to maximise product yields and improve overall process efficiency. Separations and purifications are necessary for upstream processes as well as in maximising and improving product recovery in downstream processes. These processes account for a significant fraction of the total capital and operating costs and also are highly energy intensive. Consequently, a better understanding of separation and purification processes, current and possible alternative and novel advanced methods is essential for achieving the overall techno-economic feasibility and commercial success of sustainable biorefineries. This book presents a comprehensive overview focused specifically on the present state, future challenges and opportunities for separation and purification methods and technologies in biorefineries. Topics covered include: Equilibrium Separations: Distillation, liquid-liquid extraction and supercritical fluid extraction. Affinity-Based Separations: Adsorption, ion exchange, and simulated moving bed technologies. Membrane Based Separations: Microfiltration, ultrafiltration and diafiltration, nanofiltration, membrane pervaporation, and membrane distillation. Solid-liquid Separations: Conventional filtration and solid-liquid extraction. Hybrid/Integrated Reaction-Separation Systems: Membrane bioreactors, extractive fermentation, reactive distillation and reactive absorption. For each of these processes, the fundamental principles and design aspects are presented, followed by a detailed discussion and specific examples of applications in biorefineries. Each chapter also considers the market needs, industrial challenges, future opportunities, and economic importance of the separation and purification methods. The book concludes with a series of detailed case studies including cellulosic bioethanol production, extraction of algae oil from microalgae, and production of biopolymers. Separation and Purification Technologies in Biorefineries is an essential resource for scientists and engineers, as well as researchers and academics working in the broader conventional and emerging bio-based products industry, including biomaterials, biochemicals, biofuels and bioenergy.
