A Real-Time Approach to Process Control
John Wiley & Sons Inc (Verlag)
978-1-119-99388-9 (ISBN)
the need for clean, efficient and low-cost processes is one of the
most critical challenges facing chemical engineers. The ability to
control these processes, optimizing one, two or several variables
has the potential to make more substantial savings in time, money
and resources than any other single factor.
Building on the success of the previous editions, this new third
edition of A Real-Time Approach to Process Control employs
both real industry practice and process control education without
the use of complex or highly mathematical techniques, providing a
more practical and applied approach.
Updated throughout, this edition:
?
Includes a brand new chapter on Model predictive Control (MPC)
?
Now includes wireless and web-based technologies
?
Covers bio-related systems
?
Details the new multivariable control measure developed by the
authors
?
Includes PowerPoint slides and solutions to Workshop problems on
the accompanying website: http://www.wiley.com/go/svrcek-real-time-3e
From the reviews of previous editions:
?Would appeal to practising engineers due to its
?hands on? feel for the subject matter. But more
importantly, the authors present these concepts as fundamentals of
chemical engineering, in a way that is consistent with how
professor teach at the universities.? ?Chemical
Engineering Process (CEP)
?The book has been beautifully crafted?
?Engineering Subject Centre
?Provides a refreshing approach to the presentation of
process analysis and control? ?The Chemical
Engineer
