Melt Crystallization Technology

by Tine Arkenbout-de Vroome

From the Author's Preface: There is a growing demand for ultrapure organic compounds such as fine chemicals, pharmaceuticals, and basic materials for use in the polymer industry. . . . In quite a number of cases, it is difficult or impossible to manufacture ultrapure organics efficiently using conventional separation techniques such as distillation. Moreover, conventional techniques usually require large amounts of energy. To improve the purification efficiency of organics, special techniques based on crystallization from the melt have been developed. Melt crystallization meets industry's need for a highly selective separation process for organic compounds which operates at low enough temperatures to prevent thermal degradation. Melt crystallization processes have the added advantage that they are energy-efficient and ecologically sound. Melt crystallization techniques appear to be particularly promising for upgrading organic materials and are one of the few routes that appear to be feasible for purifying starter materials for high-tech polymers. The aim of this book is to provide basic information on melt crystallization technology. . . . This monograph consists of three parts: 1. basic principles, 2. process options, and 3. technical equipment and applicability. This new book is the first unified guide and reference to an important chemical process technology. It is comprehensive and organized for easy reference. More than 150 diagrammatic representations, flow charts and photographs illustrate equipment and processes. More than 40 tables provide useful reference data.

Melt Rheology and its Applications in the Plastics Industry

by Jian Wang John M Dealy

This is the second edition of Melt Rheology and its Role in Plastics Processing, although the title has changed to reflect its broadened scope. Advances in the recent years in rheometer technology and polymer science have greatly enhanced the usefulness of rheology in the plastics industry. It is now possible to design polymers having specific molecular structures and to predict the flow properties of melts having those structures. In addition, rheological properties now provide more precise information about molecular structure. This book provides all the information that is needed for the intelligent application of rheology in the development of new polymers, the determination of molecular structure and the correlation of processability with laboratory test data. Theory and equations are limited to what is essential for the use of rheology in the characterization of polymers, the development of new plastics materials and the prediction of plastics processing behavior. The emphasis is on information that will be of direct use to practitioners. Extensive references are provided for those wishing to pursue certain issues in greater depth. While the primary audience is applied polymer scientists and plastics engineers, the book will also be of use to postgraduate students in polymer science and engineering and as a text for a graduate course.

Meltdown!: The Nuclear Disaster in Japan and Our Energy Future (Single Titles Ser.)

by Fred Bortz

Japan. March 11, 2011. 2:46 P.M. The biggest earthquake in Japan's history—and one of the world's five most powerful since 1900—devastated the Tohoku region, 320 kilometers (200 miles) northeast of Tokyo. It triggered a huge tsunami that left crippling damage in its wake. More than 13,000 people drowned, and thousands of buildings and homes were reduced to rubble. As people assessed the damage, they made the most frightening discovery of all: the Fukushima #1 nuclear power plant was seriously damaged and three of its six reactors were heading for meltdowns. Workers tried desperately—but unsuccessfully—to save them. Explosions and fires released radioactivity into the air. Within days the Japanese government declared a 20-kilometer (12-mile) evacuation zone. The future of the plant, the long-term health of those exposed to radiation, and the effects on the environment remained uncertain. Learn more about this massive catastrophe as Dr. Fred Bortz examines both the human tragedy and the scientific implications of the nuclear meltdown. Compare this disaster to similar nuclear events in the United States and in Ukraine, and move ahead with Dr. Bortz as he explores the global debate about the future of nuclear power and alternative sources of energy.

Meltdown

by James Powlik

A DEADLY SECRET LIES BURIED BENEATH THE WORLD'S LAST FRONTIER Dr. Carol Harmon has taken her research vessel, the Phoenix, deep into one of the most forbidding places in the world, the ceaselessly shifting Arctic icescape. In one frightening moment, everything goes very wrong. During a routine dive, two of her crew are ravaged by what appears to be radiation poisoning. Knowing she needs help fast, Carol calls on the person she trusts most, a man leading his own expedition on the opposite pole of the globe. Brock Garner is an oceanographer, a former Naval officer, and a man who has never quite stopped loving his ex-wife, Carol. By the time Garner arrives, a frightening scenario is taking shape: Deep beneath the ice, something is leaking deadly radiation. Worse yet, it may be only part of a bigger cataclysm. A disaster of untold proportions is looming-the world's first man-made Ice Age. A life-and-death battle is about to be unleashed...not just for the Arctic, but for the very future of Earth.

Membrane Process Design Using Residue Curve Maps

by David Glasser Diane Hildebrandt Mark Peters Shehzaad Kauchali

Design and Synthesis of Membrane Separation Processes provides a novel method of design and synthesis for membrane separation. While the main focus of the book is given to gas separation and pervaporation membranes, the theory has been developed in such a way that it is general and valid for any type of membrane. The method, which uses a graphical technique, allows one to calculate and visualize the change in composition of the retentate (non-permeate) phase. This graphical approach is based on Membrane Residue Curve Maps. One of the strengths of this approach is that it is exactly analogous to the method of Residue Curve Maps that has proved so successful in distillation system synthesis and design.
