Natural Gas Hydrates

Natural Gas Hydrates is written for the field engineer working in the natural gas industry, This book explains how, when and where hydrates form, while providing the knowledge necessary to apply remedies in practical applications, . New to the second edition, the use of new inhibitors: Kinetic Inhibitors and Anticoagulants and the topic of kinetics of hydrates. How fast do they form? How fast do they melt? New chapters on Hydrates in Nature, hydrates on the seafloor and a new section has also been added regarding the misconceptions about water dew points. Chapters on Hydrate Types and Formers, Computer Methods, Inhibiting Hydrate Formation with Chemicals, Dehydration of Natural Gas and Phase Diagrams Hydrate Dehydration of Natural Gas and Phase Diagrams have been expanded and updated along with the companion website

* Understand what gas hydrates are, how they form and what can be done to combat their formation
* Avoid the same problems BP experienced with clogged pipelines
* Presents the four most common approaches to evaluate hydrates: heat, depressurization, inhibitor chemicals, and dehydration.

Audience: Chemical engineers, petroleum engineers, Pipeline Engineers, Any engineers working with the production, transportation, or drilling of natural gas.

The petroleum industry spends millions of dollars every year to combat the formation of hydrates - the solid, crystalline compounds that form from water and small molecules - that cause problems by plugging transmission lines and damaging equipment. They are a problem in the production, transmission and processing of natural gas and it is even possible for them to form in the reservoir itself if the conditions are favorable.

?I have often thought that many technical books are written for the academic, and not for the practicing engineer. This book looks like the type that would be out on the engineers desk most of the time, rather than stuffed back in some cabinet.?

?Good mix of basic theory and application?

?Practical for everyday use.?

?Carroll uses a very practical approach that is useful for conveying concepts that are useful in resolving real-life problems with hydrates.?

?I?ve made use of the software (spreadsheets) that came with the 1st Edition. Very useful.?

?Carroll cites other books as competition. I got lucky and bought Carroll?s and haven?t needed any other, so I haven?t looked at them.?

?I have used it to resolve real problems that I might not have been able to handle as well with other approaches. I guarantee that you will not find a useful treatment of hydrates that includes how to calculate pipeline heat loss other than in Carroll?s book. I used that in handling a problem in Australia.?

After obtaining his Ph.D., John Carroll worked at the University of Alberta as a Research Associate and a Sessional Lecturer, teaching heat transfer and numerical analysis. He also worked on several research projects, resulting in many papers and conference presentations. Much of this work has been incorporated into AQUAlibrium. Dr. Carroll is the author or co-author of about 30 papers in refereed journals, nine articles in technical magazines, and approximately 25 conference presentations. He has a special interest in the application of Henry's Law. A series of papers, culminating in the recent publication of "Henry's law - Revisited" (Jan. 1999), have appeared in Chemical Engineering Progress. Other papers on Henry's Law have appeared in other publications as well. Following his term with the U. of A., he worked for Honeywell Hi-Spec Solutions (formerly SACDA) in London, Ontario. At Honeywell, he worked to develop a new thermodynamics and physical properties calculation package for their simulation software. He was the Team Leader of a group of dedicated thermodynamicists.
