The field of membrane separation technology is presently in a state
of rapid growth and innovation. Many different membrane separation
processes have been developed during the past half century and new
processes are constantly emerging from academic, industrial, and
governmental laboratories. While new membrane separation processes
are being conceived with remarkable frequency, existing processes
are also being constantly improved in order to enhance their
economic competitiveness. Significant improvements are currently
being made in many aspects of membrane separation technology: in
the development of new membrane materials with higher selectivity
and/or permeability, in the fabrication methods for high-flux
asymmetric or composite membranes, in membrane module construction
and in process design. Membrane separation technology is presently
being used in an impressive variety of applications and has
generated businesses totalling over one billion U.S. dollars
annually.
The main objective of this book is to present the principles and
applications of a variety of membrane separation processes from the
unique perspectives of investigators who have made important
contributions to their fields. Another objective is to provide the
reader with an authoritative resource on various aspects of this
rapidly growing technology. The text can be used by someone who
wishes to learn about a general area of application as well as by
the knowledgeable person seeking more detailed information.
Useful as a reference for engineers in industry and as an advanced
level text for graduate engineering students, Multiphase Flow and
Fluidization takes the reader beyond the theoretical to demonstrate
how multiphase flow equations can be used to provide applied,
practical, predictive solutions to industrial fluidization
problems. Written to help advance progress in the emerging science
of multiphase flow, this book begins with the development of the
conservation laws and moves on through kinetic theory, clarifying
many physical concepts (such as particulate viscosity and solids
pressure) and introducing the new dependent variable--the volume
fraction of the dispersed phase. Exercises at the end of each
chapterare provided for further study and lead into applications
not covered in the text itself.

This book presents new approaches to security risk analysis and
scenario building on the basis of water works such as flood
barriers and storm surge barriers. Defending flood barriers is not
only important because of climate change and rising sea levels, but
also due to the vulnerability of fresh water supplies and the
increasing number of people living in vulnerable low-lying river
and sea deltas.
Handbook of Flotation Reagents: Chemistry, Theory and Practice:
Flotation of Gold, PGM and Oxide Minerals, Volume 2 focuses on the
theory, practice, and chemistry of flotation of gold, platinum
group minerals (PGMs), and the major oxide minerals, along with
rare earths. It examines separation methods whose effectiveness is
limited when using conventional treatment processes and considers
commercial plant practices for most oxide minerals, such as
pyrochlore-containing ores, copper cobalt ores, zinc ores, tin
ores, and tantalum/niobium ores. It discusses the geology and
mineralogy of gold, PGMs, and oxide minerals, as well as reagent
and flotation practices in beneficiation. The book also looks at
the factors affecting the floatability of gold minerals and
describes PGM-dominated deposits such as Morensky-type deposits,
hydrothermal deposits, and placer deposits. In addition, case
studies of flotation and beneficiation in countries such as Canada,
Africa, Russia, Chile, and Saudi Arabia are presented. This book
will be useful to researchers, university students, and professors,
as well as mineral processors faced with the problem of
beneficiation of difficult-to-treat ores.

This book addresses the developing area of biomass for
technological applications. Written by leading researchers in the
field, the book differs from other literature available by
providing a detailed, in-depth discussion of the characteristics of
these materials. The use of biomass for technological applications
is a rapidly growing area in materials engineering and green
bioprocesses. In this approach, pre-treatments focus on the
bioavailability of nutrients and facilitate the use of biomass for
delivering byproducts (e.g. enzymes) and for bioenergy production,
both of which are discussed at length in this book. In this regard,
it explores various aspects of the structural complexity of
residual biomass produced by agricultural, industrial and livestock
activities for biotechnological purposes, and assesses both
conventional and emerging pre-treatments (e.g. biological,
enzymatic and physical-chemical). This book reveals the advantages
of these techniques, both individually and in combination, making
it an excellent resource for all readers interested in cutting-edge
applications of biomass.

synonyms, exposure limits, chemical and physical properties,
incompatibilities and reactivities, measurement methods, respirator
selections, signs and symptoms of exposure, and procedures for
emergency treatment.
Solid biofuels, in different trading forms, constitute an integral
component of the energy mix of almost all developed and developing
countries. Either in the form of pellets, briquettes, chips,
firewood, or even as raw feedstock, solid biofuels are used mainly
in the heating and power sector. Numerous sustainability concerns,
focusing on the environmental, economic and technical aspects of
solid biofuels exploitation, led to considerable advances in the
recent years in this field. These developments mainly focus on the
pre-treatment processes of the solid biomass to biofuels chain, the
minimum requirements of the produced solid biofuels, as well as the
efficiency and the environmental performance of their
thermochemical conversion routes. This work aspires to provide the
state of the art in the field of the exploitation of solid biofuels
to present the main advances as well as the major challenges of
this scientific fields. The topics presented in this book were
examined and dealt with by the authors in the past few years, in
numerous research projects and scientific publications. This book
compiles all the assembled experience of the past few years, and
aims to provide an overview of the solid biofuels exploitation
field. Presents the latest standards and considerations on solid
biofuels technical requirements; Contains numerous examples on
applications in the field of solid biofuels thermochemical
conversion, as well as the state of the art in this field; Includes
sustainability aspects, including life cycle assessment aspects and
financial concerns for the exploitation of solid biofuels.
The selection of the most adequate thermodynamic model in a
process simulation is an issue that most process engineers have to
face sooner or later. This book, conceived as a practical guide,
aims at providing adequate answers by analyzing the questions to be
answered. The analysis (first chapter) yields three keys that are
further discussed in three different chapters. The fourth chapter
illustrates the phase behavior and makes model recommendations for
the most significant industrial systems. A decision tree is
provided at the end of this chapter. In the last chapter, the key
questions are reviewed for a number of typical processes. This book
is intended for process engineers who are not specialists in
thermodynamics, but are confronted with this kind of problems and
need a reference book, as well as process engineering students who
will find an original approach to thermodynamics, complementary to
traditional lectures.
There is hardly any technical library in the world in which the
volumes of the Chemical Formulary (Volumes 1-34) do not occupy a
prominent place. Chemists both experienced and beginner,
continually refer to them. It does not duplicate any of the
formulas included in previous volumes, but lists a wide array of
modern and salable products from all branches of the chemical
industries. An excellent reference for formulation problems.

taught in our schools and colleges, concerns chiefly synthesis,
analysis, and engineering-and properly so. It is part of the right
foundation for the education of the chemist. Many a chemist
entering an Industry soon finds that most of the products
manufactured by his concern are not synthetic or definite complex
compounds, but are mixtures, blends, or highly complex compounds of
which he knows little or nothing. The literature in this field, if
any, may be meager, scattered, or obsolete. Even chemists with
years of experience In one or more Industries spend considerable
time and effort in acquainting themselves with any new field which
they may enter. Consulting chemists similarly have to solve
problems brought to them from industries foreign to them. There was
a definite need for an up-to-date compilation of formulae for
chemical compounding and treatment. Since the fields to be covered
are many and varied, an editorial board of chemists and engineers
engaged in many industries was formed. Many publications,
laboratories, manufacturing firms, and Individuals have been
consulted to obtain the latest and best information. It is felt
that the formulas given in this volume will save chemists and
allied workers much time and effort. Manufacturers and sellers of
chemicals will find, In these formulae, new uses for their
products. Non-chemical executives, professional men, and Interested
laymen will make through this volume a "speaking acquaintance" with
products which they may be using, trying or selling. It often
happens that two Individuals using the same Ingredients in the same
formula get different results. This may be due to slight deviations
in the raw materials or unfamiliarity with the intricacies of a new
technique. Accordingly, repeated experiments may be necessary to
get the best results. Although many of the formulas given are being
used commercially, many have been taken from the literature and may
be subject to various errors and omissions. This should be taken
into consideration. Wherever possible, it is advisable to consult
with other chemists or technical workers regarding commercial
production.
As a result of knowledge exchange between the academic and
industrial worlds, this book analyzes the process industries
impacted by the digital revolution that accompanies the ongoing
energy and environmental transitions. Process Industries 2 first
discusses bio-industries and analyzes the development of products
of microbial origin. It then studies all the stages of
industrialization that facilitate the progress from research to the
production of a finished product, as well as industrial management
techniques. Using concrete examples, this book presents the
instruments of the digital revolution (artificial intelligence,
virtual reality, augmented reality, the Internet of Things, digital
twins), while analyzing their impact on the supply chain and
operators. Boxes within the book, written by recognized
specialists, invite both students and professionals, who are faced
with a changing world, to reflect on the industry and the world of
tomorrow.
