Dew droplets scatter the light of the early morning sun like thousands of diamonds. Billions of passing rain droplets, refracting and internally reflecting the sunlight, form the rainbow, stretching across the sky and competing in its magnificence with the red fire ball of the sunset. Droplets are encountered not only in nature but also in a wide range of engineering applications, such as spray combustion, spray drying, spray cooling, etc., etc. ...
Deposition and aggregation of small solid particles from a liquid dispersion encountered in a variety of situations in manufacturing and process technology and in natural aquatic environments. Deposition may occur onto a surfimmersed into the suspension, that is of macroscopic dimensions compared with particle, or solids may settle due to gravity to form a sediment at the bott of the vessel containing the mixture. Aggregation involves the formati...
During the last 40 years, consumer choice has been transformed by developments in the production, distribution and retailing of food, which with improvements in the design and equipment of the domestic kitchen have facilitated a major change in our lifestyle. Perhaps the most striking development is the marketing of a wide and expanding range of chilled perishable foods. Convenience, easy preparation and the ?fresh` and ?healthy` image and an ext...
In preparing the second edition of this book, the authors have been concerned to maintain or expand those aspects of the subject that are specific to chemical and process engineering. Thus, the chapter on gas-liquid two-phase flow has been greatly extended to cover flow in the bubble regime as well as to provide an introduction to the homogeneous model and separated flow model for the other flow regimes. The chapter on non-Newtonian flow has also...
This reference guide is intended for anyone who requires a source book on food irradiation, including those in the manufacturing and retail industries, and teachers and students in academia. The extent of the information covering food irradiation is impressive but it is scattered throughout a vast literature. Our aim is to provide basic information about the major aspects of food irradiation and also to simplify access to the more detailed inform...
Drying is the oldest method of food preservation practised 6y man. Today the dehydration section of the food industry is large and extends to all countries throughout the world. Facilities range in size from simple sun driers to very large capacity, sophisticated drying installations. A very wide range of dehydrated foods is available including vegetables, fruits, meat, fish, cereal and milk products. Dehydrated soup and sauce mixes and complete ...
This book is an outgrowth of an earlier book, Chemical Reactor Design, John Wiley & Sons, 1987. The title is different and reflects a new emphasis on optimization and particularly on scaleup, a topic rarely covered in undergraduate or graduated education but of paramount importance to many practicing engineers.The treatment of biochemical and polymer reaction engineering is also more extensive than normal.Practitioners are the primary audience fo...
Ever since man walked on the face of this earth, he has consumed food to survive, to maintain his body and mind, and later for pleasure too. In the early days, he had to gather his food wherever he found it. Gradually man started to understand how to grow and cultivate his own food, and he gained more and more control over his environment. All this time, man observed and the mechanisms behind it, longing to understand what happened, what happens...
This document is intended as a typical guideline and reference book that may be applied at petroleum, petrochemical and chemical facilities. It is suggested that this document is used as a practical reference to prepare the safety review requirements for these and related industries, and their process safety management systems. This publication is intended to provide guidance to I-IAZOP (Hazard and Operability) and What-If review teams associated...
This volume, Fluidization, Solids Handling, and Processing, is the first of a series of volumes on ?Particle Technology? to be published by Noyes Publications with L. S. Fan of Ohio State University as the consulting editor. Particles are important products of chemical process industries spanning the basic and specialty chemicals, agricultural products, pharmaceuticals, paints, dyestuffs and pigments, cement, ceramics, and electronic materials. ...
Although supercritical fluid (SCF) technology is now widely used in extraction and purification processes (in the petrochemical, food and pharmaceuticals industries), this book is the first to address the new application of cleaning. Our objective was to provide a road map for readers who want to know whether SCF technology can meet their own processing and cleaning needs. It should be particularly help fbl to those striving to balance the requi...

Among the popular concerns about the environment, none ranks higher than the safety and quality of the food that we eat. Issues relating to genetically modified (GM) crops, pesticide residues in fruit and vegetables, cancer-causing chemicals, hazardous micro-organisms such as E. coli, the incidence and control of transmissible spongi form encephalopathies such as BSE and CJD, are but a few of the problem areas that receive frequent and widespread...
This book discusses recent developments and future directions in the field of membrane separation systems. It describes research needed to bring energy-saving membrane separation processes to technical and commercial readiness for commercial acceptance within the next 5 to 20 years. The assessment was conducted by a group of six internationally known membrane separations experts who examined the worldwide status of research in the seven major mem...
This volume has been written as an introductory reference and working guide to the subject of liquid filtration engineering. The book is designed to acquaint the newcomer to industry practices, and general design and operating methodology for filtration processes. Emphasis is given to pollution control applications, however the technologies and equipment described herein are equally applicable to product recovery and product purification applicat...
This handbook emphasizes the use of synthetic membranes for separations involving industrial or municipal process streams. Little will be said concerning the use of membranes in medical applications as in artificial kidneys or for controlled drug release. Most of the membrane processes are pressure driven. The notable exception to this is electrodialysis (ED) by which ions are separated under the influence of an electric field. In addition, the c...
The science of slurry hydraulics started to flourish in the 1950s with simple tests on pumping sand and coal at moderate concentrations. It has evolved gradually to encompass the pumping of pastes in the food and process industries, mixtures of coal and oil as a new fuel, and numerous mixtures of minerals and water. Because of the diversity of minerals pumped, the wide range in sizes [43 m (mesh 325) to 51 mm (2 in)], and the various physical and...
