Описание: This book provides a complete guide on tools and techniques for modeling of supercritical and subcritical fluid extraction (SSFE) processes and phenomena. It provides details for SSFE from managing the experiments to modeling and optimization. It includes the fundamentals of SSFE as well as the necessary experimental techniques to validate the models. The optimization section includes the use of process simulators, conventional optimization techniques and state-of-the-art genetic algorithm methods. Numerous practical examples and case studies on the application of the modeling and optimization techniques on the SSFE processes are also provided. Detailed thermodynamic modeling with and without co-solvent and non equilibrium system modeling is another feature of the book.
The book consists of seven chapters. Chapter 1 presents an overview of the field of supercritical and subcritical fluid extraction (SSFE) and their importance to food, cosmetic and pharmaceutical industries. Chapter 2 describes the concepts and methodologies for modeling, simulation as well as optimization. It presents conservation laws related to SFE traditional first principle modeling and optimization techniques, statistical modeling as well as advanced artificial intelligence (AI) techniques like genetic algorithm, fuzzy logic and artificial neural network (ANN). The characteristics and physical properties of palm oil as the most referred solute in the book, and descriptions of some existing palm oil industrial processes are presented in Chapter 3. In Chapter 4, the first principle methodology is applied for modeling of properties of palm oil components, mixtures and for the supercritical fluid extraction of palm oil components. Modeling applications involving advanced techniques such as AI, ANN and fuzzy logics and ANFIS are discussed in Chapter 5. Next, Chapter 6 describes experimental design concepts and procedures as well as statistical optimization techniques involving SSFE processes. Finally, optimisation of SSFE using first principle modeling and other advanced techniques are presented in Chapter 7.

Описание: Recent advances in analytical chemistry have turned it into a virtually unrecognizable science compared to a few decades ago, when it lagged behind other sciences and techniques. However, advances in analytical science have been far from universal: while innovations in instrumentation and data acquisition and processing systems have reached unprecedented levels thanks to parallel breakthroughs in computer science and chemo- metrics, progress in preliminary operations has been much slower despite their importance to analytical results. Thus, such clear trends in analytical process development as automation and miniaturization have not reached preliminary operations to the same extent, even though this area is pro- bably in the greatest need. Improvement in preliminary operations is thus an urgent goal of analytical chemistry on the verge of the twenty first century. Increased R&D endeavours and manufacture of commercially available automatic equipment for implementation of the wide variety of operations that separate the uncollected, unmeasured, untreated sample from the signal measuring step are thus crucial on account of the wide variability of such operations, which precludes development of all-purpose equipment, and the complexity of some, particularly relating to solid samples. Supercritical fluid extraction opens up interesting prospects in this context and is no doubt an effective approach to automatioI1 and mini- aturization in the preliminary steps of the analytical process. The dramatic developments achieved in its short life are atypical in many respects.

Over the past four decades, notable advancements in the theory and application of ion exchange science uncovered a wealth of knowledge that fueled new scientific pursuits and created synergies with myriad scientific endeavors. Today, pioneers continue to break new ground by synthesizing novel materials and merging the interdisciplinary fields of science and engineering.
Now in its 20th volume, Ion Exchange and Solvent Extraction: A Series of Advances chronicles the ongoing changes that drive innovation in this important field. Beginning with a review of research studies that show how functionalized ion exchange polymers serve as supports to stabilize metal nanoparticles (MNPs) without forming larger than nano aggregates, the book describes the sorption of different gases from the air by ion exchange resins and fibrous ion exchangers and discusses the selective ion exchange technology capable of removing and recovering perchlorate quantitatively through stable isotope ratio analysis of chlorine and oxygen atoms, allowing for the forensic analysis of perchlorate origin in contaminated water.
Later chapters demonstrate how numerical simulations coupled with small-scale bench-top experiments can help tailor particle size distribution and enhance the efficiency of each application, review dual-temperature ion exchange processes in which sorption and desorption are carried out solely by varying temperature, and present the preparation and characterization of a new composite material in which microparticles of clinoptilolite are embedded in a matrix of cross-linked chitosan, opening new opportunities for the natural biopolymer. The book concludes with the preparation, characterization, and field-level experience of an emerging class of "hybrid ion exchangers" that enhance the application opportunities of ion exchange resins.
Highlighting the latest and most pivotal discoveries, the 20th volume of a field standard codifies the current state-of-the-art and lays the groundwork for the next generation of growth and expansion in the field of ion exchange.
