This book offers a straightforward, informative guide to the chemicals used for gas hydrate formation and inhibition, providing the reader with the latest information on the definition, structure, formation conditions, problems, and applications of gas hydrates. The authors review not only the inhibitors used to prevent or mitigate hydrate formation, but also the conditions under which it is necessary to form hydrates quickly, which require the use of promoters. Various promoters are discussed, including their specifications, functions, advantages and disadvantages. The possibility of using natural reservoirs of gas hydrate as an energy source is also considered. Lastly, due to the difficulty of conducting experiments that reflect all conditions and concentrations, the book presents a number of models that can predict the basic parameters in the presence of the chemicals. Given its scope, the book will be of interest to professionals working in this field in an industrial context, as well as to researchers, undergraduate and graduate students of chemical engineering.

Natural gas hydrate, a solid form of natural gas and water, occurs in nature in association with deep permafrost and in offshore environments adjacent to continental margins. This report presents results of a gas hydrate research well project located at the north-eastern edge of the Mackenzie Delta. The project brought together researchers from North America and Japan to undertake the first investigation of a natural gas hydrate occurrence beneath permafrost that included extensive dedicated coring and associated engineering and scientific studies. The report compiles papers from the project in the following categories: an overview of the project, including drilling operations; a regional overview of gas hydrate occurrences, permafrost conditions, and geology in the project area; geology and biostratigraphy of the drilled cores; physical properties and geochemistry of the cores; characteristics of the gas hydrate, including chemical and physical analyses; downhole geophysics; and regional gas hydrate occurrences, production, and climate change considerations. Includes author index.

This book discusses the contemporary techniques and the latest applications in the field of nucleation, growth, inhibition and dissolution of solids. It covers techniques, including diffraction, small angle scattering, probe microscopy, optical microscopy, crystallization techniques and both atomistic and meso-scale modelling methods; and applications, which consider inorganic materials, micro-porous and meso-porous materials, molecular crystals, biomaterials, minerals, semi-conductors and pharmaceuticals. It is a key point of reference for researchers working in related fields and offers a comprehensive guide to research and opinion in this area. Faraday Discussions document a long-established series of Faraday Discussion meetings which provide a unique international forum for the exchange of views and newly acquired results in developing areas of physical chemistry, biophysical chemistry and chemical physics. The papers presented are published in the Faraday Discussion volume together with a record of the discussion contributions made at the meeting. Faraday Discussions therefore provide an important record of current international knowledge and views in the field concerned.
