Reducing atmosphere that sodium is reduced and evaporated to produce the sodium tail of the Moon (see atmosphere of the Moon). Reducing atmosphere A reducing atmosphere is an atmospheric condition in which oxidation is prevented by removal of oxygen and other oxidizing gases or vapours, and which may contain actively reducing gases such as hydrogen, carbon monoxide, and gases such as hydrogen sulphide that would be oxidized by any present oxygen. In metal processing, a reducing atmosphere is used in annealing ovens for relaxation of metal stresses without corroding the metal. A non oxidizing gas, usually nitrogen, is used, or for more
Shale gas in the United States natural gas expenditures by as much as 11.6 billion by 2025. America's Natural Gas Association (ANGA) estimates that lower gas prices will add an additional $926 of disposable household income annually between 2012 and 2015, and that the amount could increase to $2,000 by 2035. Over a 100 billion dollars is going to be invested in the US Petrochemical industry and most of it in Texas. Due to emergence of shale gas, coal consumption declined from 2009. One study finds that hyraulic fracturing has contributed to job growth and higher wages. The results of the study "suggest new oil and
