The manner in which time is captured forms the foundation for synthesis, design, and optimization in batch chemical plants. However, there are still serious challenges with handling time in batch plants. Most techniques tend to assume either a fixed time dimension or adopt time average models to tame the time dimension, thereby simplifying the resultant mathematical models. A direct consequence of this simplification is a suboptimal process. Synthesis, Design, and Resource Optimization in Batch Chemical Plants aims to close this scientific gap. Presenting state-of-the art models for the scheduling, synthesis, design, and resource optimization of batch chemical processes, this cutting-edge text: Describes different ways to represent and capture time in the optimal allocation of tasks to various units with the objective of maximizing throughput or minimizing makespan Covers synthesis and design where the objective is mainly to yield a chemical facility, which satisfies all the targets with minimum capital cost investment Deals with resource conservation aspects in batch plants, where water and energy take the center stage Synthesis, Design, and Resource Optimization in Batch Chemical Plants offers a comprehensive discussion of scheduling techniques, continuous-time formulations, and the synthesis and design of chemical plants that optimally utilize water and energy resources.

This monograph details basic concepts and tools fundamental for the analysis and synthesis of linear systems subject to actuator saturation and developments in recent research. The authors use a state-space approach and focus on stability analysis and the synthesis of stabilizing control laws in both local and global contexts. Different methods of modeling the saturation and behavior of the nonlinear closed-loop system are given special attention. Various kinds of Lyapunov functions are considered to present different stability conditions. Results arising from uncertain systems and treating performance in the presence of saturation are given. The text proposes methods and algorithms, based on the use of linear programming and linear matrix inequalities, for computing estimates of the basin of attraction and for designing control systems accounting for the control bounds and the possibility of saturation. They can be easily implemented with mathematical software packages.

Most conventional cryogenic refrigerators and liquefiers operate with pure fluids, the major exception being natural gas liquefiers that use mixed refrigerant processes. The fundamental aspects of mixed refrigerant processes, though very innovative, have not received the due attention in open literature in view of commercial interests. Hundreds of patents exist on different aspects of mixed refrigerant processes. However, it is difficult to piece together the existing information to choose an appropriate process and an optimum composition or a given application. The aim of the book is to teach (a.) the need for refrigerant mixtures, (b.) the type of mixtures that can be used for different refrigeration and liquefaction applications, (c.) the different processes that can be used and (d.) the methods to be adopted for choosing the components of a mixture and their concentration for different applications.

In contrast to nuclear plants and aerospace systems, human error is largely ignored in quantitative risk assessment for petroleum and chemical plants. Because of this, current risk analysis methods are able to calculate and predict only about one-third of the accidents happening in practice. Human Error in Process Plant Design and Operations: A Practitioner's Guide shows you how to develop a comprehensive risk assessment that includes human error. Based on the well-known SRK model of human error, this book represents a practical collection of examples and statistics from more than 30 years of study, with many examples of the practical application of methods. The book provides a complete overview of the various types of human error, including operator error, hindrances and inability to function, errors in observation, errors in performing standard procedures, errors in supervisory control, errors in decision making and planning, infractions and violations, design errors, and errors in procedures. It then goes on to identify human error potential and probabilities, and discusses techniques and methodologies that can be implemented to minimize human errors and prevent accidents. The result of the author's observations of human error over a lifetime of work as an operator, as a commissioning coordinator, and as an operations manager, the book demonstrates how to analyse, manage, and mitigate many types of error. By taking advantage of the author's experience and expert knowledge, and by applying the techniques and methodologies illustrated in this book, you will be able to make changes which will make work easier, error free, clearly understood, and more congenial.

Selenium (Se) is a chemical element of concern due to its toxicity and increasing anthropogenic release to the environment. Se oxyanions, selenite and selenate, are water-soluble, bioavailable and toxic, whereas elemental selenium, Se(0), is solid and less toxic. Nevertheless, Se(0) is potentially harmful as particulate Se(0) has been reported to be bioavailable to bivalves, to fish and also prone to re-oxidation. In the current work we investigated the reduction of selenite and selenate using pure and mixed microbial cultures. A novel strain of Pseudomonas moraviensis showing high Se tolerance was isolated, classified and characterized for the first time. Biogenic Se(0) shows colloidal properties due to its nanosize scale and negatively-charged biopolymer coating. To address the need for efficient solid-liquid separation of biogenic Se(0) prior to environmental discharge, we tested and compared several physical-chemical separation methods. Centrifugation and filtration can be efficiently used for Se(0) separation but they are not feasible at the industrial scale due to prohibitive costs. Alternatively, chemical coagulation by metal salts, e.g. aluminum sulfate and ferric chloride, resulted in high removal rates around 90%. Electrocoagulation reached the highest colloidal Se(0) removal efficiency of 97% when using iron electrodes. In conclusion, biogenic Se(0) must be removed in a biological post-treatment step and several approaches described in this work could be successfully used.

Since the third edition of this reference was completed, there have been major changes in the global chemical industry. With less emphasis on new processes for making basic chemicals and more emphasis on pollution prevention and waste disposal, petrochemical processes are giving way to biochemical processes. These changes are reflected in the new processes being developed, many of which have their own names. In addition, niche improvements are still being made in petrochemistry, and some of these processes have new names as well. Gathering and defining a large portion of special named processes that may fall outside standard chemical texts or be scattered among industry manuals, Encyclopedic Dictionary of Named Processes in Chemical Technology, Fourth Edition provides a single-source reference on an extensive array of named processes. It provides concise descriptions of those processes in chemical technology that are known by special names that are not self-explanatory. While overviews of the chemical technology industry are present in other books, most of the names defined within this volume are unique to this compilation. This reference includes named processes in current commercial use around the world, processes that have been or are being piloted on a substantial scale, and even obsolete processes that have been important in the past. The length of the dictionary entries reflects their importance and topicality. The text includes references that document the origins of the processes and review the latest developments. Written by a highly experienced and respected author, this user-friendly text is presented in a practical dictionary format that is useful for a broad audience including industrial chemists and engineers.
