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.
Methanol - The Chemical and Energy Feedstock of the Future offers a visionary yet unbiased view of methanol technology.

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.

As a result of their unique physical properties, biological membrane mimetics, such as liposomes, are used in a broad range of scientific and technological applications. Liposomes, Lipid Bilayers and Model Membranes: From Basic Research to Application describes state-of-the-art research and future directions in the field of membranes, which has evolved from basic studies of the physicochemical properties of amphiphiles to their application in industry and medicine. Written by leading researchers in their fields, this book describes basic and applied research, and serves as a useful reference for both the novice and the expert. Part one covers a range of basic research topics, from theory and computational simulations to some of the most up-to-date experimental research. Topics discussed include soft matter physics of membranes, nonlamellar phases, extraction of molecules by amphiphiles, lipid models for membrane rafts, membrane dynamics, nanodiscs, microemulsions, active membranes, as well as interactions of bilayers with drugs or DNA to treat disease or for gene transfer, respectively. Part two of the book focuses on technological applications of amphiphiles, such as liposome-based nanoparticles for drug delivery, formulation of liposomes for prolonged in vivo circulation and functionalization for medical purposes, novel drug delivery systems for increased drug loading, and the use of tethered membranes for bio-sensing applications. Chapters also describe the use of liposomes in textile dyeing and how lipidic nanoparticles are used by the food industry.
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.
Over the past several decades, the theme of supramolecular
chemistry (SC) has permeated nearly all aspects of chemical
endeavor. Not surprisingly, it has also pervaded the field of
solvent extraction (SX), inspiring the framework for this volume of
Ion Exchange and Solvent Extraction. In addition, tools for
studying aggregation have grown increasingly sophisticated, leading
to a greater understanding of what we now recognize as SC phenomena
in SX. Volume 21, Supramolecular Aspects of Solvent Extraction
identifies how supramolecular behavior occurs and is studied in the
context of SX and how SC is influencing the direction of SX.

This volume contains ?ve chapters. The topics covered are the cathodic reduction of nitrate, for which the key issues are pr- uct selectivity and current ef?ciency; a discussion of ionic l- uids known as molten or fused salts in key industrial processes; the properties of nanowires made of metals and semiconductors by means of electrodeposition into porous templates and template synthesis; and an overview of a range of alloys used in elect- plating, and trends in ammonium electrolysis. Also, included is a review of the applications of synchroton x-ray scattering to the electrochemical interphase. Chapter 1 by Celia Milhano and Derek Pletcher reviews the cathodic reduction of nitrate as a "truly fascinating reaction" since processes for nitrate removal from drinking water and effluents and reducing nitrates in nuclear waste is an essential step in n- lear waste disposal. The authors also review electrochemical membrane technology not involving the cathodic reduction of - trate. In Chapter 2, the authors discuss substances called ionic l- uids, and the fact that this is really a new more modern term for molten or fused salts. However, the label of ionic liquids is usu- ly applied to the liquid state of salts at or near room temperature, which is a way to differentiate low-melting salts from higher me- ing cousins. These molten or fused salts form the basis of several key industrial processes, and this chapter is primarily devoted to the non-haloaluminate ionic liquids as reviewed by Tetsuya Tsuda and Charles L. Hussey.
