Electrode Processes and Electrochemical Engineering

Abstract

No part of this book may be reproduced, stored in a retrieval system, or transmitted in any form or by any means, electronic, mechanical, photocopying, microfilming, recording, or otherwise, without written permission from the Publisher FOREWORD This book has been planned and written by Dr. Hine with his knowledge and experience in electrochemical science and engineering for over thirty years since he joined with me at Kyoto University in 1948.This book is unique and is useful for engineers as well as scientists who are going to work in any interdisciplinary field connected with electrochemistry.Science is sure to clarify the truth of nature as well as bring prosperity and an improvement to the welfare of human beings. The origin of the word "science" is the same as of "conscience," which means the truth of our heart.When we consider a scientific and technological subject, first we classify it into the components and/or factors involved, and then we clarify them individually. Second, we combine them to grasp the whole meaning and feature of the subject under discussion. Computers may help us greatly, but how to establish the software that will be most desirable for our purposes is of great importance. We need to make these efforts ourselves, and not decorate with borrowed plumes.With this concept in mind, this book is attractive because the author describes the basic science in electrochemistry and practice, and discusses the electrochemical engineering applications as a combination of science and technology.Furthermore, Dr. Hine discusses the present situation and future trends in the industry with a number of drawings and photographs. He also tries to compare the electrochemical process to other competitive processes. He does this well because he has experience both in the field of science and in chemical process industries. Also, he is very happy that he has many friends worldwide who give him useful information and ideas.Dr. Hine attended classes in electrical engineering at the technical college in Osaka, then he came to my laboratory at the Department of Industrial Chemistry, Kyoto University, where he received his doctorate degree. He has studied hard and specialized in electrochemical engineering. This book is the fruit of his efforts. v vi FOREWORD It is a pleasure to provide these introductory remarks for Fumio Hine, who is so willing to work actively with an international sense.

A comparative study of electrochemical reactor configurations for the decomposition of copper cyanide effuent

“…The intermediate layers are separated by porous insulators and function as bipolar electrodes. Numerous patents and applications have appeared in the past twenty years [6]. E1-Ghaoui [1] found that in a bipolar reactor, high flow rate could cause bypass phenomena and reduce the current efficiency.…”

On the potential utility of 2 × 2 contingency tables in electrochemical engineering

“…Coeuret and Storck [1] state that in EE, all phenomena occurring simultaneously in an electrochemical reactor have to be accorded an overall consideration. Hine [2] affirms that EE is the bridge connecting science and practice in the field of electrochemistry, and that it concerns ''... practical subjects related either directly or indirectly to industrial processes...''; EE, therefore, uses principles of electrochemistry and chemical engineering.…”

Utilização da Simulação de Processo para Prever o Comportamento do Sistema de Tratamento de Efluente Ácido em uma Indústria de Cloro Soda

“…De acordo com Hine (1985), o processo de produção industrial de cloro e soda de tecnologia de diafragma consiste basicamente em uma área de tratamento de salmoura, eletrólise, evaporação da soda e processamento de cloro e hidrogênio, no entanto na unidade da BRASKEM em Alagoas contém também o processo de mineração e produção de dicloroetano (DCE), conforme a Figura 1. A solução aquosa de sal a uma concentração de 320 g/l de NaCl, também conhecida como salmoura, é obtida na mineração e encaminhada para o tratamento.…”
