Chemical Process Industries
The chemical industry comprises the companies that produce industrial chemicals. Central to the modern world economy, it converts raw materials ( oil, natural gas, air, water, metals, and minerals) into more than 70,000 different products. The plastics industry contains some overlap, as some chemical companies produce plastics as well as chemicals. Various professionals are involved in the chemical industry including chemical engineers, chemists and lab technicians. History Although chemicals were made and used throughout history, the birth of the heavy chemical industry (production of chemicals in large quantities for a variety of uses) coincided with the beginnings of the Industrial Revolution. Industrial Revolution One of the first chemicals to be produced in large amounts through industrial processes was sulfuric acid. In 1736 pharmacist Joshua Ward developed a process for its production that involved heating saltpeter, allowing the sulfur to oxidize and combine wi ...

FEMA - 37677 - Aerial Of A Louisiana Oil Refinary Repaired Since Katrina
The Federal Emergency Management Agency (FEMA) is an agency of the United States Department of Homeland Security (DHS), initially created under President Jimmy Carter by Presidential Reorganization Plan No. 3 of 1978 and implemented by two Executive Orders on April 1, 1979. The agency's primary purpose is to coordinate the response to a disaster that has occurred in the United States and that overwhelms the resources of local and state authorities. The governor of the state in which the disaster occurs must declare a state of emergency and formally request from the President that FEMA and the federal government respond to the disaster. The only exception to the state's gubernatorial declaration requirement occurs when an emergency or disaster takes place on federal property or to a federal asset—for example, the 1995 bombing of the Alfred P. Murrah Federal Building in Oklahoma City, Oklahoma, or the Space Shuttle ''Columbia'' in the 2003 return-flight disaster. While on-th ...

Prestonpans
Prestonpans ( gd, Baile an t-Sagairt, Scots: ''The Pans'') is a small mining town, situated approximately eight miles east of Edinburgh, Scotland, in the Council area of East Lothian. The population as of is. It is near the site of the 1745 Battle of Prestonpans (first called the Battle of Gladsmuir, then renamed the Battle of Tranent, and later still renamed the Battle of Prestonpans - although evidence shows the battle occurred a few miles outside of town). Prestonpans is "Scotland's Mural Town", with many murals depicting local history. History Foundation According to legend Prestonpans was founded in the 11th century by a traveller named Althamer, who became shipwrecked on the local beach/coastal area. Finding it impossible to get home, the survivors of the wreck decided to remain where they were and founded a settlement named "Althamer" in honour of their leader. The monks of Newbattle and Holyrood arrived in the district in the 12th century and, by 1198, were under ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glass
Glass is a non-crystalline, often transparent, amorphous solid that has widespread practical, technological, and decorative use in, for example, window panes, tableware, and optics. Glass is most often formed by rapid cooling (quenching) of the molten form; some glasses such as volcanic glass are naturally occurring. The most familiar, and historically the oldest, types of manufactured glass are "silicate glasses" based on the chemical compound silica (silicon dioxide, or quartz), the primary constituent of sand. Soda–lime glass, containing around 70% silica, accounts for around 90% of manufactured glass. The term ''glass'', in popular usage, is often used to refer only to this type of material, although silica-free glasses often have desirable properties for applications in modern communications technology. Some objects, such as drinking glasses and eyeglasses, are so commonly made of silicate-based glass that they are simply called by the name of the material. Despite bei ...

Soda Ash
Sodium carbonate, , (also known as washing soda, soda ash and soda crystals) is the inorganic compound with the formula Na2CO3 and its various hydrates. All forms are white, odourless, water-soluble salts that yield moderately alkaline solutions in water. Historically, it was extracted from the ashes of plants growing in sodium-rich soils. Because the ashes of these sodium-rich plants were noticeably different from ashes of wood (once used to produce potash), sodium carbonate became known as "soda ash". It is produced in large quantities from sodium chloride and limestone by the Solvay process. Hydrates Sodium carbonate is obtained as three hydrates and as the anhydrous salt: * sodium carbonate decahydrate (natron), Na2CO3·10H2O, which readily effloresces to form the monohydrate. * sodium carbonate heptahydrate (not known in mineral form), Na2CO3·7H2O. * sodium carbonate monohydrate (thermonatrite), Na2CO3·H2O. Also known as crystal carbonate. * anhydrous sodium carbonate ( n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glasgow
Glasgow ( ; sco, Glesca or ; gd, Glaschu ) is the most populous city in Scotland and the fourth-most populous city in the United Kingdom, as well as being the 27th largest city by population in Europe. In 2020, it had an estimated population of 635,640. Straddling the border between historic Lanarkshire and Renfrewshire, the city now forms the Glasgow City Council area, one of the 32 council areas of Scotland, and is governed by Glasgow City Council. It is situated on the River Clyde in the country's West Central Lowlands. Glasgow has the largest economy in Scotland and the third-highest GDP per capita of any city in the UK. Glasgow's major cultural institutions – the Burrell Collection, Kelvingrove Art Gallery and Museum, the Royal Conservatoire of Scotland, the Royal Scottish National Orchestra, Scottish Ballet and Scottish Opera – enjoy international reputations. The city was the European Capital of Culture in 1990 and is notable for its architecture, cult ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
