The 89th edition continues the format of the past, with new tables added for atomic radii, composition and properties of common oils and fats, global warming potential of greenhouse gases, weather-related scales, energy content of fuels, properties of gas clathrate hydrates, melting curve of mercury, enthalpy of hydration of gases, and electrical resistivity of graphite materials.
Sloan and Koh, both affiliated with the Colorado School of Mines, describe all major aspects of natural gas clathrate hydrates in this book/CD-ROM package for engineers and researchers.
Ethylene glycol is widely used to discourage the formation of natural gas clathrates (hydrates) in long multiphase pipelines that are used to convey natural gas from remote gas fields to a gas processing facilities.
In fact, natural gas clathrates make up a substantially greater source of carbon than the estimated natural gas reserves (up to 2,500 gigatonnes of carbon compared with 230 GtC for natural gas).
Mixed gas clathrates are more stable, yet denser, at Europa's outer surface than pure O2 clathrates and could more easily sink through the thick ice crust to the subsurface ocean.
Although inert gas clathrates had been described previously, this was the first charge-transfer compound of xenon to be stable at room temperature.
