Production-integrated environmental protection is synonymous with - reducing the amount of potential pollutants at source - reducing the consumption of resources and energy - recycling and utilization of residues and used products, and therefore a topic of considerable current interest. No chemical process exists that produces only the product desired. Therefore it is an important aim of the chemical industry to reduce the environmental effects of residues of chemical processes. This can be achieved by: - optimizing processes - applying new synthesis routes - improving selectivity - replacing auxiliaries that have a harmful effect on the environment - production-integrated recovery of residues to name just a few possibilities. If you want to know more about them, have a look at Protection-Integrated Environmental Protection and Waste Management. There you will find examples from the chemical industry where modification of existing manufacturing processes or the design of new processes has led to reduction of environmental pollution. Data from companies are given who operate world-wide reflecting a multi national situation.
This comprehensive work shows how to design and develop innovative, optimal and sustainable chemical processes by applying the principles of process systems engineering, leading to integrated sustainable processes with 'green' attributes. Generic systematic methods are employed, supported by intensive use of computer simulation as a powerful tool for mastering the complexity of physical models. New to the second edition are chapters on product design and batch processes with applications in specialty chemicals, process intensification methods for designing compact equipment with high energetic efficiency, plantwide control for managing the key factors affecting the plant dynamics and operation, health, safety and environment issues, as well as sustainability analysis for achieving high environmental performance. All chapters are completely rewritten or have been revised. This new edition is suitable as teaching material for Chemical Process and Product Design courses for graduate MSc students, being compatible with academic requirements world-wide. The inclusion of the newest design methods will be of great value to professional chemical engineers. - Systematic approach to developing innovative and sustainable chemical processes - Presents generic principles of process simulation for analysis, creation and assessment - Emphasis on sustainable development for the future of process industries
The two-volume reference work Chemical Technology and the Environment provides readers with knowledge on contemporary issues in environmental pollution, prevention and control, as well as regulatory, health and safety issues as related to chemical technology. It introduces and expands the knowledge on emerging "green" materials and processes and "greener" energy technology, as well as more general concepts and methodology including sustainable development and chemistry and green chemistry. Based on Wiley's renowned, Kirk-Othmer Encyclopedia of Chemical Technology, this compact reference features the same breadth and quality of coverage and clarity of presentation found in the original.
This concise introduction to the fundamentals of biological treatment of wastewater describes how to model and integrate biological steps into industrial processes. The book first covers the chemical, physical and biological basics, including wastewater characteristics, microbial metabolism, determining stoichiometric equations for catabolism and anabolism, measurements of mass transfer and respiration rates and the aerobic treatment of wastewater loaded with dissolved organics. It the moves on to deal with such applications and technologies as nitrogen and phosphorus removal, membrane technology, the assessment and selection of aeration systems, simple models for biofilm reactors and the modeling of activated sludge processes. A final section looks at the processing of water and the treatment of wastewater integrated into the production process. Essential reading for chemists, engineers, microbiologists, environmental officers, agencies and consultants, in both academia and industry.

This practical how-to-do book deals with the design of sustainable chemical processes by means of systematic methods aided by computer simulation. Ample case studies illustrate generic creative issues, as well as the efficient use of simulation techniques, with each one standing for an important issue taken from practice. The didactic approach guides readers from basic knowledge to mastering complex flow-sheets, starting with chemistry and thermodynamics, via process synthesis, efficient use of energy and waste minimization, right up to plant-wide control and process dynamics. The simulation results are compared with flow-sheets and performance indices of actual industrial licensed processes, while the complete input data for all the case studies is also provided, allowing readers to reproduce the results with their own simulators. For everyone interested in the design of innovative chemical processes.
In this book a quantitative, dynamic model is developed to explain and explore the diffusion of green new products in a business-to-business (B2B) context. Considering the case of emerging bioplastics, this goal is reached through a mixed-methods design, combining qualitative and quantitative methods over three phases. After an interview study with key-value chain actors an experimental vignette technique is applied to further study relevant factors in the micro (firm) level adoption process. Integrating the empirical findings, the diffusion model is developed and simulated at the macro (industry) level using a System Dynamics (SD) approach. Results explain the underlying dynamics and critical conditions for adoption to become self-sustaining.
While the treatment of water and exhaust gas using ultraviolet (UV) light offers both ecological and economic advantages, information on photo-initiated advanced oxidation technologies (AOTs) has been dispersed among various journals and proceedings until now. This authoritative and comprehensive handbook is the first to cover both the photochemical fundamentals and practical applications, including a description of advanced oxidation processes (AOPs) and process engineering of suitable photoreactors. The author presents various real-world examples, including economic aspects, while many references to current scientific literature facilitate access to current research topics relevant for water and air industries. Throughout, over 140 detailed figures visualize photochemical and photophysical phenomena, and help in interpreting important research results. From the foreword by James R. Bolton (President of Bolton Photosciences Inc., Executive Director of the International Ultraviolet Association (IUVA)): "Prof. Oppenländer is well qualified to write about the AOPs/AOTs, since he has contributed to this literature in a very significant manner. This book will be of considerable value to graduate students, science and engineering faculty, scientists, process engineers and sales engineers in industry, government regulators and health professionals."
