Counter-Current Extraction


Book Description

Counter-Current Extraction: An Introduction to the Design and Operation of Counter-Current Extractors provide useful conclusions and results pertaining to counter-current extraction. This book aims to present illustrations of the various mathematical techniques as tools as well as means to an end. Organized into eight chapters, this book begins with an overview of the various aspects of the transfer of a single solute between two immiscible phases in counter-current flow. This text then describes all possible factors and obtains their relationship to the extraction factor and number of stages or transfer units. Other chapters consider the flows and concentrations in counter-current forward and back extraction. This book discusses as well the optimization of forward and back extraction using counter-current flow in differential and stagewise extractors. The final chapter deals with further applications of counter-current extractions. Undergraduates and researchers involved in the design and operation of counter-current extractors will find this book useful.




Countercurrent Chromatography


Book Description

Covering definitions, concepts, and applications, Countercurrent Chromatography recounts the developments in two types of liquid-liquid chromatography termed countercurrent-high-speed countercurrent chromatography (HSCCC) and centrifugal partition chromatography (CPC)-as well as the HSCCC-derived cross-axis CCC, a versatile technique for purification in biotechnology applications. The text investigates mechanisms for mixing liquid phases, particularly hydrostatic techniques for CPC and hydrodynamic for coil planet centrifuges. It also explores the use of countercurrent chromatography in inorganic analysis, chiral separation, and the separation of natural products.

Principles of Adsorption and Adsorption Processes


Book Description

The first up-to-date summary and review for the fundamental principles and industrial practice of adsorption separation processes in more than 30 years. Emphasizes the understanding of adsorption column dynamics and the modeling of adsorption systems, as well as fundamental aspects of kinetics and equilibria.




Countercurrent Chromatography


Book Description

Countercurrent chromatography (CCC) is a separation technique in which the stationary phase is a liquid. The mobile phase is also a liquid, so biphasic liquid systems with at least two solvents are used. Centrifugal fields are used to hold the liquid stationary phase while pushing the liquid mobile phase through it. This comprehensive reference covers recent advancements in the two types of CCC machines: the high speed CCCs without rotary seals and with coiled spools and centrifugal partition chromatographs (CPC) with rotary seals and interconnected channels. Written by leading international experts in the CCC field, the book focuses on the liquid nature of the stationary phase: giving newcomers the basis to do CCC efficiently and rapidly; explaining the art of obtaining a biphasic liquid system; describing the flow patterns in both CPC and high speed CCC machines; showing possible other uses of a liquid stationary phase; presenting a wealth of applications in the separation of organic, pharmaceutical and inorganic mixtures; and demonstrating that even supercritical fluids can be used in CCC.




How Animals Work


Book Description

A study of comparative physiology that explains the ways in which specific bodily systems function in different species.




Currents and Countercurrents


Book Description

Soon after the inception of Buddhism in the sixth or fifth century B.C.E., the Buddha ordered his small band of monks to wander forth for the welfare and weal of the many, a command that initiated one of the greatest missionary movements in world religious history. But this account of a monolithic missionary movement spreading outward from the Buddhist homeland of India across the Asian continent is just one part of the story. The case of East Asian Buddhism suggests another tale, one in which the dominant eastward current of diffusion creates important eddies, or countercurrents, of influence that redound back toward the center. These countercurrents have had significant, even profound, impact on neighboring traditions. In East Asia perhaps the most important countercurrent of influence came from Korea, the focus of this volume. Chapters examine the role played by the Paekche kingdom in introducing Buddhist material culture (especially monastic architecture) to Japan and the impact of Korean scholiasts on the creation of several distinctive features that eventually came to characterize Japanese Pure Land Buddhism. The lives and intellectual importance of the monks Sungnang (fl. ca. 490) and Wonch’uk (613–696) are reassessed, bringing to light their role in the development of early intellectual schools within Chinese Buddhism. Later chapters discuss the influential teachings of the semi-legendary master Musang (684–762), the patriarch of two of the earliest schools of Ch’an; the work of a dozen or so Korean monks active in the Chinese T’ient’ai tradition; and the Huiyin monastery.
