Porter Ranch, Los Angeles
Porter Ranch is a suburban neighborhood of the City of Los Angeles, in the northwest portion of the San Fernando Valley. History The Porter family acquired part of Rancho Ex-Mission San Fernando in 1874. Porter Ranch community started as a housing tract in the community of Northridge. This was along San Fernando Mission Blvd west of Reseda Blvd circa 1960–1963. Almost no homes were north of Rinaldi Street until the area was annexed by the City of Los Angeles in 1965. These homes were only accessible via Tampa. Approximately 50 homes of the original tract was destroyed north of San Fernando Mission Blvd to build the 118 freeway. The new home construction that was completed in the Porter Ranch area in the 1990s–2000s, including the Renaissance Summit development, was mired in controversy and Los Angeles politics in the late 1980s and early 1990s. This largely undeveloped area on the very edge of the San Fernando Valley slated for a master-planned $2 billion real estate a ...

Methane Emissions
Increasing methane emissions are a major contributor to the rising concentration of greenhouse gases in Earth's atmosphere, and are responsible for up to one-third of near-term global heating. During 2019, about 60% (360 million tons) of methane released globally was from human activities, while natural sources contributed about 40% (230 million tons). Reducing methane emissions by capturing and utilizing the gas can produce simultaneous environmental and economic benefits. Since the Industrial Revolution, concentrations of Atmospheric methane, methane in the atmosphere have more than doubled, and about 20 percent of the warming the planet has experienced can be attributed to the gas. About one-third (33%) of anthropogenic greenhouse gases, anthropogenic emissions are from gas release during the mining, extraction and delivery of fossil fuels; mostly due to gas venting and gas leaks from both active fossil fuel infrastructure and orphan wells. Russia is the world's top methane e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Odorant
An aroma compound, also known as an odorant, aroma, fragrance, flavoring or flavor, is a chemical compound that has a smell or odor. For an individual chemical or class of chemical compounds to impart a smell or fragrance, it must be sufficiently Volatility (chemistry), volatile for transmission via the air to the olfactory system in the upper part of the nose. As examples, various fragrant fruits have diverse aroma compounds, particularly strawberries which are plant breeding, commercially cultivated to have appealing aromas, and contain several hundred aroma compounds. Generally, molecules meeting this specification have molecular weights of less than 310. Flavors affect both the sense of taste and Olfaction, smell, whereas fragrances affect only smell. Flavors tend to be naturally occurring, and the term ''fragrances'' may also apply to synthetic compounds, such as those used in cosmetics. Aroma compounds can naturally be found in various foods, such as fruits and their pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tert-Butylthiol
''tert''-Butylthiol, also known as ''tert''-butyl mercaptan (TBM), and abbreciated ''t''-BuSH, is an organosulfur compound with the formula (CH3)3CSH. This thiol has a strong odor. It is considered a flavoring agent. Preparation ''tert''-Butylthiol was first prepared in 1890 by Leonard Dobbin by the reaction of zinc sulfide and ''t''-butyl chloride. The compound was later prepared by the reaction of the Grignard reagent, ''t''-BuMgCl, with sulfur to give the corresponding thiolate, followed by hydrolysis. This preparation is shown below: :''t''-BuMgCl + S → ''t''-BuSMgCl :''t''-BuSMgCl + H2O → ''t''-BuSH + Mg(OH)Cl It is made industrially by the reaction of isobutylene with hydrogen sulfide over a clay (silica alumina) catalyst. Reactions ''tert''-Butylthiol is deprotonated by lithium hydride in an aprotic solvent such as hexamethylphosphoramide (HMPA). The resulting lithium thiolate salt has been used as demethylating reagent. For example, treatment with 7-methyl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natural Gas
Natural gas (also fossil gas, methane gas, and gas) is a naturally occurring compound of gaseous hydrocarbons, primarily methane (95%), small amounts of higher alkanes, and traces of carbon dioxide and nitrogen, hydrogen sulfide and helium. Methane is a colorless and odorless gas, and, after carbon dioxide, is the second-greatest greenhouse gas that contributes to global climate change. Because natural gas is odorless, a commercial odorizer, such as Methanethiol (mercaptan brand), that smells of hydrogen sulfide (rotten eggs) is added to the gas for the ready detection of gas leaks. Natural gas is a fossil fuel that is formed when layers of organic matter (primarily marine microorganisms) are thermally decomposed under oxygen-free conditions, subjected to intense heat and pressure underground over millions of years. The energy that the decayed organisms originally obtained from the sun via photosynthesis is stored as chemical energy within the molecules of methane and other ...

Aliso Canyon Oil Field
The Aliso Canyon Oil Field (also Aliso Canyon Natural Gas Storage Field, Aliso Canyon Underground Storage Facility) is an oil field and natural gas storage facility in the Santa Susana Mountains in Los Angeles County, California, north of the Porter Ranch neighborhood of the City of Los Angeles. Discovered in 1938 and quickly developed afterward, the field peaked as an oil producer in the 1950s, but has remained active since its discovery. One of its depleted oil and gas producing formations, the Sesnon-Frew zone, was converted into a gas storage reservoir in 1973 by the Southern California Gas Company, the gas utility servicing the southern half of California. This reservoir is the second-largest natural gas storage site in the western United States, with a capacity of over 86 billion cubic feet of natural gas. Currently it is one of four gas storage facilities owned by Southern California Gas, the others being the La Goleta Gas Field west of Santa Barbara, Honor Rancho near Ne ...
