Unified Separation Science

Unifies the complex welter of techniques used for chemical separations by clearly formulating the concepts that are common to them. The mass transport phenomena underlying all separation processes are developed in a simple physical-mathematical form. The limitations and optimum performance of alternative separation techniques and the factors enhancing and limiting separation power can thus be described and explored. Generously illustrated and contains numerous exercises. Long awaited in the scientific community, it breaks new ground in understanding separation processes.

A comprehensive, integrated view of separation science Introduction to Separation Science offers a unified treatment of the fundamentals and practical applications of separation. The book places an emphasis on laboratory and analytical separations and takes this unified approach to address the fact that practical applications in separation have been developed and used in a variety of unrelated disciplines. The result is a complete overview of separation techniques within these varied, disparate areas of practice, providing the perfect guide to the reader who wishes to become familiar with separation techniques in fields outside their own.

Separation science plays a critical role in maintaining our standard of living and quality of life. Many industrial processes and general necessities such as chemicals, medicines, clean water, safe food, and energy sources rely on chemical separations. However, the process of chemical separations is often overlooked during product development and this has led to inefficiency, unnecessary waste, and lack of consensus among chemists and engineers. A reevaluation of system design, establishment of standards, and an increased focus on the advancement of separation science are imperative in supporting increased efficiency, continued U.S. manufacturing competitiveness, and public welfare. A Research Agenda for Transforming Separation Science explores developments in the industry since the 1987 National Academies report, Separation and Purification: Critical Needs and Opportunities. Many needs stated in the original report remain today, in addition to a variety of new challenges due to improved detection limits, advances in medicine, and a recent emphasis on sustainability and environmental stewardship. This report examines emerging chemical separation technologies, relevant developments in intersecting disciplines, and gaps in existing research, and provides recommendations for the application of improved separation science technologies and processes. This research serves as a foundation for transforming separation science, which could reduce global energy use, improve human and environmental health, and advance more efficient practices in various industries.

Volume two of the series focuses on the topics of extraction, filtration, heatless adsorption, hydrometallurgical extraction, interfacial phenomena, separation of gases by regenerative sorption, various polymeric membrane systems, such as electrodialysis, ultrafiltration, reverse osmosis. Gas and liquid separations by selective permeation through polymeric membrane, and the origin of separate system. The last topic, as a special feature of interest, provides an analysis of the genesis and development of new separation techniques.
