A detailed inventory of greenhouse gas emissions from upstream oil and gas activities in Canada for the year 2000 estimated that fugitive equipment leaks had a global warming potential equivalent to the release of 17 million metric tonnes of carbon dioxide, or 12 percent of all greenhouse gases emitted by the sector, [9] while another report put fugitive emissions at 5.2% of world greenhouse ...
Electron-beam furnaces are used for production and refining of high-purity metals (especially titanium, vanadium, tantalum, niobium, hafnium, etc.) and some exotic alloys. [1] The EB furnaces use a hot cathode for production of electrons and high voltage for accelerating them towards the target to be melted.
Gas leaks can damage or kill plants. [4] [5] In addition to leaks from natural gas pipes, methane and other gases migrating from landfill garbage disposal sites can also cause chlorosis and necrosis in grass, weeds, or trees. [6] In some cases, leaking gas may migrate as far as 100 feet (30 m) from the source of the leak to an affected tree. [7]
Most processes in a streamer discharge are two-body processes, where an electron collides with a neutral molecule. An important example is impact ionization, where an electron ionizes a neutral molecule. Therefore, the mean free path is inversely proportional to the gas number density. If the electric field is changed linearly with the gas ...
The fourth category of furnace is the high-efficiency condensing gas furnace. High efficiency condensing gas furnaces typically achieve between 90% and 98% AFUE. [3] A condensing gas furnace includes a sealed combustion area, combustion draft inducer and a secondary heat exchanger. The primary gain in efficiency for a condensing gas furnace, as ...
In atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals. [1] For example, the electron configuration of the neon atom is 1s 2 2s 2 2p 6 , meaning that the 1s, 2s, and 2p subshells are occupied by two, two, and six ...
A report from a group of Texas environmental nonprofits released in June found around 2,600 reported gas leaks from 2010-2021 in the U.S. pipeline system resulting in serious injury or death ...
The structure is reminiscent of cuprate superconductors, except that the copper atom arrangement in the latter is a square lattice. [2] The cobalt atoms have formal oxidation state 4−x. Namely, the fully reduced compound NaCoO 2 can be interpreted as Na + · Co 3+ · (O 2−) 2.
