advantages and limitations of various approaches to design and analysis.
This is supported by two appendices (one on the method of characteristics,
the other on the method of collocation). A third appendix provides a
synopsis of the PSA patent literature.

Adsorption Calculations and Modeling (C. Tien, Butterworth-Heine-
mann, Boston, 1994)
This book is a compendium of models and calculation procedures for the
design and analysis of physical adsorption separations. The author's
intention was to avoid duplication, as far as possible, with the standard texts
by Ruthven (1984), Faust and Aly (1987) and Yang (1987) and so some
subjects such as pressure swing adsorption and thermal swing adsorption are
not discussed in great detail. Instead, topics such as biological carbon
adsorption, adsorption with impregnated adsorbents, and characterization
of solutions of unknown composition have been given a more complete
coverage. Gas phase and liquid phase separations have been treated as far as
possible on a unified basis and are treated with equal emphasis. Thermody-
namics, adsorption equilibria and adsorption rate phenomena, including
summaries of theories for multicomponent systems, are covered in depth.
Subsequent chapters deal with calculations for batch and continuous flow
tanks, and for fixed beds. The book is supplied with a computer disk which
contains several computer programs so that the reader can carry out simple
calculations. Programs are included for equilibrium adsorption calculations
(single and multicomponent systems), batch adsorption calculations and
fixed bed adsorption calculations.

Separation Technology: The Next Ten Years (edited by J. Garside,
Institution of Chemical Engineers, Rugby, 1994)
In his invited contribution to this book, S. Sircar first explains the
development of the role of adsorption technology as a key separation
technique for the process industries. The principles of pressure and vacuum
swing adsorption are described with particular reference to air separation
for both oxygen and nitrogen production. The roles of individual steps in
each cycle are addressed. Sircar secondly discusses some of the challenges to
be faced in the design of new and improved PSA processes. These challenges
relate to the complex nature of process cycles, to fundamental understand-
ing of multicomponent gas-solid interactions, to the successful development
of simplified specific models, and to the understanding of adsorbent
heterogeneity and its effect on multicomponent gas adsorption character-
istics before a priori designs can be made with acceptable accuracy and
confidence.
