Design of Distillation Column Control Systems

Design of Distillation Column Control Systems
P. Buckley , J. Shunta, W. Luyben | 1985-01-01 00:00:00 | Butterworth-Heinemann | 576 | Chemical Engineering
Product Description
A distillation column is both multivariable and nonlinear - and it consumes immense quantities of energy. Yet, despite the desigh challenges it presents, it is still the most popular unit operation for refining in industrial plants today. Much has been published on the subject of distillation column design, but much remains to be explained. That is why this book is unique. In a departure from the more traditional empirical and theoretical approaches, it introduced the reader to the practical realm, by presenting quantitative design techniques that have been demonstrated to be useful and valid over the course of hundreds of actual applications.

The book is divided into three main parts. Part I, an introduction, presents an industrial perspective of control objectives. It discusses briefly the relationship between column design features and column controllability. It thus provides a short refresher course for chemical engineers and background for those trained in other branches of engineering. Part II, Concepts and Configurations, discusses column overhead and base arrangements, typical control schemes, and some hardware considerations. Part III is dedicated to quantitative design. Mathematical models are presented for pressure and differential pressure controls, liquid level control, and composition control of binary distillation.

Emphasis on topics of primary interest to the control engineer
Essentially nonmathematical treatment
Ideal for those involved in troubleshooting existing columns as well to design engineers

Gem and Ornamental Materials of Organic Origin

Gem and Ornamental Materials of Organic Origin
Maggie Campbell Pedersen | 2004-01-01 00:00:00 | Butterworth-Heinemann | 283 | Do It Yourself
The materials covered in the book include Amber and Copal; Jet; Ivory; Bone; Antler; Rhino horn; Horn; Tortoiseshell; Pearl; Shell; Coral, and other materials of plant and animal origin that have been used as gem or ornamental material. The book describes how to recognise them and how to distinguish them from the materials most commonly used to immitate them, for example plastic.

A comprehensive list of materials is included and each is presented with details of its origin, availability and conservation status, examples of, and a brief history of, their use. Organics fit together because of their origins, because they are constantly used together, have similar histories and were the earliest gem materials used.

200 colour images are included for ease of reference and identification, allowing you to identify this material by sight, avoiding the usual gemological tests which ruin them.

Organics occur in modern and antique jewellery, in decorative items and in some furniture, and this book draws all the information together to provide the first complete overview of the subject.

* A unique reference book comprehensively documenting organic materials
* Highly illustrated colour filled book for ease of reference
* Learn the background and how to identify organic material

Physical Chemistry in Depth

Physical Chemistry in Depth
Johannes Karl Fink | 2009-10-01 00:00:00 | springer | 532 | Chemistry
"Physical Chemistry in Depth" is not a stand-alone text, but complements the text of any standard textbook on "Physical Chemistry" into depth having in mind to provide profound understanding of some of the topics presented in these textbooks. Standard textbooks inPhysical Chemistry start with thermodynamics, deal with kinetics, structure of matter, etc. The "Physical Chemistry in Depth " follows this adjustment, but adds chapters that are treated traditionally in ordinary textbooks inadequately, e.g., general scaling laws, the graphlike structure of matter, and cross connections between the individual disciplines ofPhysical Chemistry . Admittedly, the text is loaded with some mathematics, which is a prerequisite to thoroughly understand the topics presented here. However, the mathematics needed is explained at a really low level so that no additional mathematical textbook is needed.

Voice Over IPv6: Architectures for Next Generation VoIP Networks

Voice Over IPv6: Architectures for Next Generation VoIP Networks
| 2006-04-11 00:00:00 | | 0 | VoIP/IP Telephony


IPv6 (Internet Protocol version 6) is the future of Internet telephony. And this book is your guide to that future.

IPv6 is the replacement for the currently used IPv4 (Internet Protocol version 4). IPv6 will offer increased IP addresses (full 128-bit addresses, compared to the 32-bit addresses of IPv4), enhanced security, and greater robustness. It will also be fully `backwards compatible` with existing IPv4 systems. These capabilities will finally make Internet telephony a viable competitor to conventional switched telephone networks. In this book, Dan Minoli clearly explains IPv6 and how telephone networks can be built on its foundations.

This is not just another IPv6 book; instead, it focuses on those aspects of IPv6 relevant to Internet telephony systems and voice networks. Minoli uses a compare/contrast approach, exploring where IPv6 is similar to IPv4 and where it differs, to let you quickly grasp the essence of IPv6 and the similarities (and differences) between current IPv4-based systems and IPv6-based systems.

If you will be designing, implementing, or maintaining the next generation of Internet telephony systems, then you need the information in this book!

*Explains the essential concepts of IPv6 and how they relate to Internet telephony
*Describes how Internet telephony systems using IPv6 are different from, and better than, Internet telephony systems based on the older IPv4 standard
*Discusses how to transition existing IPv4 Internet telephony systems and conventional switched systems to IPv6-based systems
*Extensive treatment of security issues, including IP layer encryption and authentication methods
*Explains connection techniques, including `plug and play` approaches, for equipment used in IPv6 systems

* The first title describing how the next generation Internet protocol-IPv6-can be used for Internet telephony
* Explains IPv6 as it applies to Internet telephony (VoIP)
* Shows how IPv6 gives better security, QoS, and signal integrity in Internet telephony

Deception

Deception
Jonathan Kellerman | 2010-03-30 00:00:00 | | 0 | Fiction
Alex Delaware fans will enjoy Deception. The plot is tight, the balance between Alex/Milo just about right, the cutesy-poo interchanges with Alex's luthier/love kept to a bare minimum. A substitute teacher/tutor at an elite Westwood prep school turns up dead, packed with dry ice. With a taste for Grey Goose and a roving eye that extends beyond her relationship with a pudgy, gambler/salesman, there are any number of possible suspects and motives for the icing. The problem is that the LAPD Chief's son is a student at the school and the Chief fears that any adverse publicity could jeopardize the school's reputation and, hence, the son's chances for admission to Yale.

It's great to see the Chief again, a model of insight/cleverness yoked with snarky political incorrectness. In a world where coptalk and copspeak are the coin of the realm, you can see why he is the head honcho. He tries to keep Milo on a short leash (with predictable, negative results) as Milo and Alex investigate the pomps and works of prep schools and the politics of the SAT's/ACT's. Alex gets to use a bit of his psychological training; we get to see some of the dark side of L.A. and the even darker side of L.A.'s prep schools.

This is a solid outing, not the best of the series necessarily, but one which is smooth, tight and to the point. The chief and his son are worlds apart in their takes on things; you'll like both.

Learning Technology in Transition

Learning Technology in Transition
Jane K. Seale | 2003-01-01 00:00:00 | Taylor & Francis | 166 | Education
In April 2003, The Association for Learning Technology (ALT) celebrated its tenth anniversary and this book has been produced in order to commemorate this landmark achievement. It represents a collaboration between key members of ALT and members of ALTs' sister organisations: SURF in Holland and ASCILITE in Australia.
The aims of the book are to use the topic of "institutional implementation" to present a review of the impact of learning technology on tertiary education over the past few years; and to highlight and discuss key changes and developments that are shaping present and future activities and consider the implications for individual enthusiasts who work in the field of learning technology. The book outlines the context in which individual enthusiasts have operated and institutional implementation has occurred over the last ten years.
Four key themes are highlighted throughout the book:
* the individual enthusiast and their role in institutional implementation;
* the institutional enthusiast and their role in local and global e-learning initiatives;
* finding the evidence to justify enthusiasm and underpin implementation;
* reinventing the individual enthusiast.
