Sulphur trioxide has a great affinity for water. It produces sulphuric acid with violence and liberation of great heat. If it escapes accidently it creates a sulphuric acid mist. This monograph explains what is known about the effects of sulphuric acid mist when it comes into contact with humans. It covers the properties, manufacture, storage and handling of sulphur trioxide and oleum and includes modelling of mist formation and dispersion. Five appendices detail exposure, animal studies and past incidents, with particular reference to the data required for computer modelling.

Control chemical processes to get the results you want Invaluable to chemical and environmental engineers as well as process designers, Chemical Process and Design Handbook shows you how to control chemical processes to yield desired effects efficiently and economically. The book examines each of the major chemical processes, such as reactions, separations, mixing, heating, cooling, pressure change, and particle size reduction and enlargement -- in logically arranged alphabetical chapters, providing you with an understanding of the essential qualitative analysis of each. The Handbook, from expert James Speight: Emphasizes chemical conversions -- chemical reactions applied to industrial processing Provides easy-to-understand descriptions to explain reactor type and design Describes the latest process developments and possible future improvements or changes

A New Approach to ICSE Chemistry for Class X has been revised in accordance with the latest syllabus prescribed by the Council for the Indian School Certificate Examination, New Delhi for Class X. The main strength of the book lies in the presentation of scientific content which has been so arranged that the topics are linked with each other and do not cause any unnecessary burden on the mind of the student. Salient features of this book are as follows. * Clear, simple and easy language * A large number of chemical reactions along with experimental observations * Full-sized diagrams, as expected from a student in the examination * Topic-wise Video Lectures as a support for effective learning * Concepts supplemented by suitable day-to-day examples * Periodic Table showing mass number; atomic number of various elements along with the list of actual names of the elements. * Highlighted important terms and definitions * Well-designed exercises to assess conceptual, reasoning skill and application-based learning as per the latest recommendations of ICSE board * Solved numerical problems at the end of each chapter to help the students solve numericals on their own * A chapter on Practical Chemistry to help students in their laboratory work. * The latest Solved ICSE Specimen Paper has been given. * Scan QR codes given at the end of each chapter to get the solution of chapter-wise ICSE Board Examination Questions. We hope this book will prove useful to fellow teachers and students. Suggestions for further improvement of this book shall be gratefully acknowledged. -Author

This book presents a complete, in-depth analysis for on the impact of liquid sulfur dioxide and liquid sulfur trioxide to carry out complex and difficult sulfonations, as well as manufacture of sulfuric acid with a CAPEX requirement of less than half, an area requirement less than one-third, and no emission of sulfur dioxide. The processes described in this volume represents an innovative approach relevant to the current manufacturing processes of sulfuric acid, sulfamic acid, para toluene sulfonic acid and other sulfonated product.

By some measure the most widely produced chemical in the world today, sulfuric acid has an extraordinary range of modern uses, including phosphate fertilizer production, explosives, glue, wood preservative and lead-acid batteries. An exceptionally corrosive and dangerous acid, production of sulfuric acid requires stringent adherence to environmental regulatory guidance within cost-efficient standards of production. This work provides an experience-based review of how sulfuric acid plants work, how they should be designed and how they should be operated for maximum sulfur capture and minimum environmental impact. Using a combination of practical experience and deep physical analysis, Davenport and King review sulfur manufacturing in the contemporary world where regulatory guidance is becoming ever tighter (and where new processes are being required to meet them), and where water consumption and energy considerations are being brought to bear on sulfuric acid plant operations. This 2e will examine in particular newly developed acid-making processes and new methods of minimizing unwanted sulfur emissions. The target readers are recently graduated science and engineering students who are entering the chemical industry and experienced professionals within chemical plant design companies, chemical plant production companies, sulfuric acid recycling companies and sulfuric acid users. They will use the book to design, control, optimize and operate sulfuric acid plants around the world. - Unique mathematical analysis of sulfuric acid manufacturing processes, providing a sound basis for optimizing sulfuric acid manufacturing processes - Analysis of recently developed sulfuric acid manufacturing techniques suggests advantages and disadvantages of the new processes from the energy and environmental points of view - Analysis of tail gas sulfur capture processes indicates the best way to combine sulfuric acid making and tailgas sulfur-capture processes from the energy and environmental points of view - Draws on industrial connections of the authors through years of hands-on experience in sulfuric acid manufacture

This book is about Sulph(on)ation Technology in its technical entirety, aiming at superiority in final product quality, raw material utilisation, sustained plant reliability and safety, minimisation of liquid effluent and gaseous emissions; it is about the total quality of the operation. It will be of value to engineers and chemists who are, or will be, involved in the practical daily operation of sulphonation plants or R&D activities. The book can also be used as a tool for the teacher in preparing fmal year projects in a chemical engineering curriculum. The book covers sulphonation of alkylbenzenes, primary alcohols, alcohol ethers, alpha-olefIns and fatty acid methyl esters, with a strong emphasis on the sulphur-based S~/air sulphonation technology. The first part deals with raw material specifications, hazards, storage, handling and physical properties. In the following section the process chemistry is discussed, indicating main chemical reactions, undesired parallel and consecutive reactions, exothermal heat effects and all other process chemistry data that are relevant for process selection and equipment design. The section about the actual process equipment from the various plant equipment suppliers (Ballestra, Chemithon, Mazzoni, Meccaniche Modeme and Lion Corp.) takes into account the chemical reaction engineering aspects derived from the sulphonation technology processing chemistry. Product quality, product storage and handling, product safety and physical properties are the contents of the next section. The effluent handling and exhaust gas treatment of the SOiair sulphonation technology are further discussed in detail.
