Process machines are critical to the profitability of processes. Safe, efficient and reliable machines are required to maintain dependable manufacturing processes that can create saleable, on-spec product on time, and at the desired production rate. As the wards of process machinery, we wish to keep our equipment in serviceable condition.

One of the most challenging aspects of a machinery professional or operator''s job is deciding whether an operating machine should be shut down due to a perceived problem or be allowed to keep operating. If he or she wrongly recommends a repair be conducted, the remaining useful machine life is wasted, but if he or she is right, they can save the organization from severe consequences, such as product releases, fires, costly secondary machine damage, etc. This economic balancing act is at the heart of all machinery assessments.

Troubleshooting is part science and part art. Simple troubleshooting tables or decision trees are rarely effective in solving complex, real-world machine problems. For this reason, the authors want to offer a novel way to attack machinery issues that can adversely affect the reliability and efficiency of your plant processes. The methodology presented in this book is not a rigid "cook book" approach but rather a flexible and dynamic process aimed at exploring process plant machines holistically, in order uncover the true nature the problem at hand.

When installed and operated properly, general purpose steam turbines are reliable and tend to be forgotten, i.e., out of sound and out of mind.  But, they can be sleeping giants that can result in major headaches if ignored.  Three real steam turbine undesirable consequences that immediately come to mind are:

A major goal of this book is to provide readers with detailed operating procedure aimed at reducing these risks to minimal levels.  Start-ups are complicated by the fact that operators must deal with numerous start-up scenarios, such as:

It is not enough to simply have a set of procedures in the control room for reference.  To be effective, operating procedures must be clearly written down, taught, and practiced—until they become habit.

The perfect primer for anyone responsible for operating or maintaining process gas compressors.

Gas compressors tend to be the largest, most costly, and most critical machines employed in chemical and gas transfer processes. Since they tend to have the greatest effect on the reliability of processes they power, compressors typically receive the most scrutiny of all the machinery among the general population of processing equipment. To prevent unwanted compressor failures from occurring, operators must be taught how their equipment should operate and how each installation is different from one another.

The ultimate purpose of this book is to teach those who work in process settings more about gas compressors, so they can start up and operate them correctly and monitor their condition with more confidence. Some may regard compressor technology as too broad and complex a topic for operating personnel to fully understand, but the author has distilled this vast body of knowledge into some key, easy to understand lessons for the reader to study at his or her own pace.

This groundbreaking new work is a must-have for any engineer, operator, or manager working with process compressors.

Process Machinery Handbook: For Field Personnel, Decision Makers, and Students equips newcomers and seasoned professionals with essential insights into the diverse world of process machinery, empowering them to understand unique performance characteristics, common failure modes, and effective strategies for enhancing reliability in their operations.

Any professional working at a production site for any length of time knows that process machinery comes in a wide range of designs and sizes, but not all process machines are considered equal. Some machines are more critical to the process than others, some are small, some are very large, some spin fast, and some turn relatively slowly. The great diversity in their construction and application can be daunting to those new to the industry and sometimes even challenge machinery veterans. There are many common concepts that apply to all equipment types, but each equipment category has its own unique application and performance characteristics, including cavitation in liquid handling pumps, surging in centrifugal gas compressors, rotor instability in high-speed centrifugal compressors, and the effect of the compression ratio on a reciprocating compressor’s the discharge temperature. It is also essential for users to understand how and why different types of machinery fail, keeping in mind that the common failure modes differ greatly between rotating machinery types. We know that by addressing the common types of failure modes associated with each machine type, we can achieve significant improvements in their reliability.

The first step in organizing an effective machinery reliability program is committing to performing failure analyses and gathering failure statistics. These activities will help users learn how and why their machines are failing. The next step is to continuously modify machines, processes, and methods to avoid common failures. Process Machinery Handbook: For Field Personnel, Decision Makers, and Students gives students and professionals alike the tools they need to understand the fundamentals of working with rotating machinery.
