Forming gas treatment of metals, because it reduces oxides on the metal surface. Forming gas Forming gas is a mixture of hydrogen (mole fraction varies) and nitrogen. It is sometimes called a "dissociated ammonia atmosphere" due to the reaction which generates it: It can also be manufactured by thermal cracking of ammonia, in an ammonia cracker or forming gas generator. Forming gas is used as an atmosphere for processes that need the properties of hydrogen gas. Typical forming gas formulations (5% H2 in N2) are not explosive. It is used in chambers for gas hypersensitization, a process in which photographic film is
Natural gas in the United States was still increasing. The most commonly quoted producer price for natural gas is the Louisiana-based Henry Hub price, which is futures-traded on NYMEX. A barrel of oil releases about 5.8 million BTU when burned, so that 5.8 MCF of gas (at the standard one thousand BTU per cubic foot) releases about the same energy as a barrel of oil. Sometimes gas containing 5.8 million BTU is defined as a "barrel of oil equivalent for energy calculation purposes. When describing reserves or production, however, the oil and gas industry more commonly uses the rounded number of 6 MCF of gas (or
