A unique resource for process measurement Basic Process Measurements provides a unique resource explaining the industrial measuring devices that gauge such key variables as temperature, pressure, density, level, and flow. With an emphasis on the most commonly installed technologies, this guide outlines both the process variable being measured as well as how the relevant measuring instruments function. The benefits of each technology are considered in turn, along with their potential problems. Looking at both new and existing technologies, the book maintains a practical focus on properly selecting and deploying the best technology for a given process application. The coverage in Basic Process Measurements enables the practitioner to: Resolve problems with currently installed devicesUpgrade currently installed devices to newer and better technologiesAdd instruments for process variables not previously measurableEvaluate device installations from a perspective of both normal process operating conditions and abnormal conditionsDetermine the best technology for a given set of process conditions Designed for a wide range of technical professionals, Basic Process Measurements provides a balanced treatment of the concepts, background information, and specific processes and technologies making up this critical aspect of process improvement and control.
Practical Process Control

Practical Process Control

Practical Process Control (loop tuning and troubleshooting). This book differs from others on the market in several respects. First, the presentation is totally in the time domain (the word "LaPlace" is nowhere to be found). The focus of the book is actually troubleshooting, not tuning. If a controller is "tunable", the tuning procedure will be straightforward and uneventful. But if a loop is "untunable", difficulties will be experienced, usually early in the tuning effort. The nature of any difficulty provides valuable clues to what is rendering the loop "untunable". For example, if reducing the controller gain leads to increased oscillations, one should look for possible interaction with one or more other loops. Tuning difficulties are always symptoms of other problems; effective troubleshooting involves recognizing the clues, identifying the root cause of the problem, and making corrections. Furthermore, most loops are rendered "untunable" due to some aspect of the steady-state behavior of the process. Consequently, the book focuses more on the relationship of process control to steady-state process characteristics than to dynamic process characteristics. One prerequisite to effective troubleshooting is to "demystify" some of the characteristics of the PID control equations. One unique aspect of this book is that it explains in the time domain all aspects of the PID control equation (including as the difference between the parallel and series forms of the PID, the reset feedback form of the PID equation, reset windup protection, etc.) The book stresses an appropriate P&I (process and instrumentation) diagram as critical to successful tuning. If the P&I is not right, tuning difficulties are inevitable. Developing and analyzing P&I diagrams is a critical aspect of troubleshooting.

Learn to Design the Best Control Configuration for Any Distillation Column Today, distillation is by far the most common separation technique used in the chemical and petroleum industries. All distillation columns need to be carefully controlled in order to meet specified production and quality levels. Distillation Control enables readers to do this by approaching the subject from a process to develop, analyze, and troubleshoot all aspects of column controls. Readers are efficiency and effectiveness and minimizing coats. Distillation Control begins with a chapter dedicated to underlying principles, including separation processes, reflux and boilup ratios, and composition dynamics. Next, the author covers such critical topics as: Composition controlPressure control and condensersReboilers and feed preheatersApplication of feedforwardUnit optimizationComplex towers As readers progress through the text, they’ll discover that the best control configuration for a distillation column is largely determined using steady-state process characteristics. The stage-by-stage separation models that the author sets forth for column design, therefore, provide information that is essential in developing the optimal control configuration. In addition to its clear explanations, Distillation Control is filled with clear diagrams and illustrations that clarify complex concepts and guide readers through multi-step procedures. Engineers as well as other professionals working in process facilities that use distillation to separate materials will fin that this book enables them to implement the latest tested and proven distillation control methods to meet their particular processing needs.

This book fills the gap between basic control configurations (Practical Process Control) and model predictive control (MPC). For those loops whose performance has a direct impact on plant economics or product quality, going beyond simple feedback or cascade can improve control performance, or specifically, reduce the variance about the target. However, the effort required to implement such control technology must be offset by increased economic returns from production operations. The economic aspects of the application of the various advanced control technologies are stressed throughout the book.

What should you do if you find a bug on your plate? How do you ask someone to dance? What's the least offensive way to enjoy your cigar? These and other questions of social decorum are answered in this classic etiquette book. Published just before the Civil War, this volume offers enduring advice for courtesy-challenged men. Common-sense suggestions for socializing, exercise, flirting, dining, and dressing reveal that the basics of proper behavior haven't changed all that much ― and in situations where they have, today's gentlemen may find something worth learning from their predecessors.Suggestions for the best way to behave, as well as how not to behave, include conduct in the street ("Avoid striking your umbrella against those which pass you"); making calls ("No man in the United States, excepting His Excellency, the President, can expect to receive calls unless he returns them"); and dating ("Any lover-like airs or attitudes, although you may have the right to assume them, are in excessively bad taste in public"). These and other etiquette tips provide intriguing glimpses of nineteenth-century society in addition to a wealth of timeless counsel on behaving with sincerity, dignity, and kindness in our own day and age.
Jaroslav Hasek

Jaroslav Hasek

Cecil Parrott

Cambridge University Press

pokkari
This 1982 book was the first major critical study of Jaroslav Hašek and his most important literary creation, The Good Soldier Švejk. For many people Hašek's book is simply extremely funny. Cecil Parrott begins from the point of view that a closer examination of the conditions under which the book was written reveal it to be a much deeper work than it appears on the surface: a tragic as well as a comic masterpiece. A leading authority on Hašek, Parrott wrote the definitive biography, The Bad Bohemian, and translated the unexpurgated version of Švejk and many of Hašek's short stories. This book is lucidly written and aimed at the non-specialist reader who requires guidance in coming to terms with this strange book. All quotations are translated, and the book also includes a number of illustrations including the only sketch of Švejk that Hašek approved.
Rimbaud

Rimbaud

Cecil Arthur Hackett

Cambridge University Press
1981
pokkari
Originally published in 1981, this critical survey of Rimbaud's work was intended mainly for the student and the general reader, but the specialist will also find in it fresh and illuminating comments. While taking into account the 'two Rimbauds', the visionary poet and the trader, and the two aspects of the work, the poems and the letters, Professor Hackett's chief concern is the poetry. He concentrates on the more important of the early verse poems, the Lettre du voyant, the 1872 verse poems, and the major writings, Illuminations and Une Saison en enfer. Although he makes some shrewd criticisms, Professor Hackett shows Rimbaud's work to be that of a major poet who has had a decisive influence on the development of French poetry. English translations of the quotations are given at the end of the book, together with additional notes, chronology table and a select bibliography that lists books and articles which should prove helpful.
