Preface
This book is presenting to explain the principles of process integration, the use of
pinchtechnologyaswellasenergyrecyclinginoil,gas,petrochemicalandindustrial
processes.
Wemadeeveryefforttopreparethisbookasacompletecontentoverviewofall
aspects in similar references in the field of energy recovery in oil, gas and petro-
chemicals, by considering standards and the way of performing heat exchangers
networkandimplementingtheengineering,procurementandconstructionprojects
also the helpful experiences in optimizing them via latest process modeling of the
largestengineeringcompanies,forthosewhoareinvolvinginthisfieldandwould
befocusingontheirfutureplans.
It is hoped that this book will serve as a guide and reference for professors,
technicians, craftsmen, managers, students and graduated people in various engi-
neering majors, especially chemical and process engineering. Meanwhile the con-
tentpresentedprovidesenoughbasicinformationasfeedforallstudentsinterested
in energy industry and its technical, process and operational topics. We wish that
the contents of this book would be a guide for developing the future and various
applicableplansfortheenergy,oil,gasanddownstreamindustries.
