| Found in | Hanford Separation Science Workshop (1st : 1991 : Richland, Wash.). Proceedings of the First Hanford Separation Science Workshop, 1993: p. iii (separating the wastes into portions that can be recycled and others that can be stabilized and permanently stored as grout or glass forms; the separation methods must take into account the characteristics of the individual waste stream, the type of storage and location, and the interactions among the various waste components; separation methods for environmental restoration and for minimization, recovery, and recycle of mixed and radioactive wastes) p. v (advanced separation methods such as selective crystallization, selective leaching, physical separation, solvent extraction, and ion exchange) Pruett, D.J. Separation science and technology--an ORNL perspective, 1986: p. 4 (Only recently has separation science come to be viewed as a single field, rather than as a group of fields made up of a series of unrelated separations methods) p. 5 (In general, a "separation" is an operation by which a mixture is divided into at least two fractions having different compositions. "Separation science" is the study of the fundamental properties and processes that make a separation possible. "Separation technology" is the application of this fundamental information to practical problems of separation and purification; include operations as different as the electromagnetic separation of isotopes, the purification of materials by solvent extraction, and the processing of ores by froth flotation. Further, the dividing line between "fundamental" and "applied" work is no clearer in separation research than in any other area of scientific investigation) National Academies of Sciences, Engineering, and Medicine (U.S.). Committee on a Research Agenda for a New Era in Separation Science. A research agenda for transforming separation science, 2019: p. 7 (Separation, as the term is used in this report, is the division of a chemical mixture (a mixture of molecules or colloidal particles) into its constituent or distinct elements. The purpose of a chemical separation process is usually to enrich a product stream in one or more of the components of the original mixture. In some cases, the purpose of the separation process is to divide the mixture fully into its pure components; Separations are an integral component of a wide array of technologies that are necessary to meet societal needs; separation processes) p. 9 (separation technologies) p. 10 (separation science and technology) p. 25 (the field of chemical separations) |
