Preface to the Distillation Collection
For more than 5,000 years distillation has been used as a method for separating
binary and multicomponent liquid mixtures into pure components. Even today, it
belongs to the most commonly applied separation technologies and is used at
such a large scale worldwide that it is responsible for up to 50% of both capital
and operating costs in industrial processes. It moreover absorbs about 50% of the
total process energy used by the chemical and petroleum refining industries every
year.Giventhatthechemicalindustryconsumed19%oftheentireenergyinEurope
(2009),distillation is the bigdriverof overall energyconsumption.
Althoughdistillationisconsideredthemostmatureandbest-understoodsepara-
tion technology, knowledge on its manifold aspects is distributed unevenly among
different textbooks and manuals. Engineers, by contrast, often wish for just one
referencebookinwhichthemostrelevantinformationispresentedinacondensed
andaccessibleform.Distillationaimsatfillingthisgapbyofferingasuccinctover-
viewofdistillationfundamentals,equipment,andapplications.Students,academics,
and practitioners will find in Distillation a helpful summary of pertinent methods
and techniques and will thus be able to quickly resolve any problems in the field
of distillation.
This bookprovidesa comprehensiveand thorough introductioninto all aspects
of distillation, covering distillation history, fundamentals of thermodynamics,
hydrodynamics, mass transfer, energy considerations, conceptual process design,
modeling, optimization and control, different column internals, special cases of
distillation, troubleshooting, and the most important applications in various
industrialbranches, including biotechnologicalprocesses.
Distillation forms part of the “Handbook of Separation Sciences” series and is
available as a paper book and as an e-book, thus catering to the diverging needs
ofdifferentreaders.Itisdividedintothreevolumes:“Fundamentalsandprinciples”
(EditorsA.Go´rakandE.Sorensen),“Equipmentandprocesses”(EditorsA.Go´rak
and Z(cid:1). Oluji(cid:3)c), and “Operation and applications” (Editors A. Go´rak and H.
Schoenmakers). Each volume contains chapters written by individual authors with
acclaimed expertise in their fields. In addition to that, readers will find cross-
references to other chapters, which allow them to gain an extensive overview of
state-of-the-arttechnologiesandvariousresearchperspectives.Helpfulsuggestions
for further reading concludeeach chapter.

Distillation: Operation
Preface to
and Applications
ThisisthelastofthreebooksinaseriescoveringallaspectsofDistillation.Thisbookon
Operation and Applications provides an overview on all operational aspects and
describestechnologiesinvariousapplicationfields.Itconsistsof10chaptersofdifferent
authors.Theapproachtothecontenttogetherwiththechoiceofsubjectsandexamples
are the authors’ choice but the book represents a comprehensive overview on the
operationalprinciplesandthewidespreadapplicationrangeofdistillationingeneral.
In Chapter 1 control and operation principles for columns including coupled
mass and heat integrated configurations and plantwide control are described. The
secondchapterdealswithcolumntroobleshooting.Analysisofdisturbancesisintro-
ducedandmethodstosolvetheproblemsareoutlined.Strategiesforunderstanding
problems in connection with plant operation are given and special investigation
techniques are explained in detail. Chapter 3 is on performance testing techniques
forindustrialscalecolumnswithalltypesofinternals.Instructionsforrunningtests
and proceduresto evaluate the results aregiven.
The following four chapters describe in detail the configurations of distillation
sequences used in different applications. The content of Chapter 4 is distillation
in refining processes. Flowsheets of such processes are explained in detail and the
improvement potentials even for well-established processes are shown including
the choice of special and new column internals. Chapter 5 deals with distillation
in bulk chemicals industry, in which columns of similar dimensions as in refining
processes are used but physical properties of the separated components are quite
different. Consequently new operational challanges like foaming, fouling, and
designproblemsconnectedwithcolumnefficienciesarise.InChapter6theaspects
of distillation in small-scale plants for specialty chemicals that frequently need
low-pressure conditions are discussed. Special aspects are low liquid loads in the
columns, aqueous three phase systems, and reactions that may occur. In Chapter 7
veryspecialapplicationofairdistillationispresented.Thedifferentprocessvariants
at the extreme conditions of pressure and temperature are explained and problems
like maldistributionat the lowliquid loads are adressed.
