Public Company
A public company is a company whose ownership is organized via shares of share capital, stock which are intended to be freely traded on a stock exchange or in over-the-counter (finance), over-the-counter markets. A public (publicly traded) company can be listed on a stock exchange (listing (finance), listed company), which facilitates the trade of shares, or not (unlisted public company). In some jurisdictions, public companies over a certain size must be listed on an exchange. In most cases, public companies are ''private'' enterprises in the ''private'' sector, and "public" emphasizes their reporting and trading on the public markets. Public companies are formed within the legal systems of particular states and so have associations and formal designations, which are distinct and separate in the polity in which they reside. In the United States, for example, a public company is usually a type of corporation, though a corporation need not be a public company. In the United Kin ...

Papua, Indonesia
Papua is a province of Indonesia, comprising the northern coast of Western New Guinea together with island groups in Cenderawasih Bay to the west. It roughly follows the borders of the Papuan customary region of Tabi Saireri, and is divided into eight regencies () and one city (''kota''), the latter being the provincial capital of Jayapura. It is bordered by the nation of Papua New Guinea to the east, the Pacific Ocean to the north, Cenderawasih Bay to the west, and the provinces of Central Papua and Highland Papua to the south. The province also shares maritime boundaries with Palau in the Pacific. Papua, along with the five other Papuan provinces, has a higher degree of autonomy level compared to other Indonesian provinces. Before 2003, the province (known as Irian Barat from 1962 to 1973 and Irian Jaya from 1973 to 2002) covered the entirety of Western New Guinea, a region also known as "Papua". In 2002, Papua adopted its current name and was granted a special autonomou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herman Frasch
Herman Frasch r Hermann Frasch(December 25, 1851 – May 1, 1914) was a chemist, mining engineer and inventor known for his work with petroleum and sulfur. Biography Early life He was the son of Johannes and Frieda Henrietta (Bauer) Frasch. Both his parents were natives of Stuttgart. His father was burgomaster of Gaildorf. Herman attended the Latin school in Gaildorf and was then apprenticed to a bookseller in nearby Schwäbisch Hall. At the age of 16 or 19, he left the apprenticeship and sailed from Bremen to New York, then took the train to Philadelphia. After his arrival in the United States, he became a lab assistant to John Michael Maisch at the Philadelphia College of Pharmacy. Engineering career Oil career In 1875, Frasch invented a recovery process for tin scrap and process to make white lead from galena. He patented a process for refining paraffin wax in 1876, and sold the patent to Standard Oil, for whom he became a consulting chemist based in Cleveland. In 1884, Fr ...

Union Sulphur Company
The Union Sulphur Company was an American sulfur mining corporation founded in 1896 by the famous inventor Herman Frasch. It utilized the Frasch Process to extract previously inaccessible sulfur deposits located beneath swampland in Louisiana. The Union Sulphur Company dominated the world sulfur market until its patents expired in 1908. Its success led to the development of the present-day city of Sulphur, Louisiana. After its sulfur patents expired, the company transitioned into oil and natural gas production and was renamed the Union Sulphur & Oil Company and later the Union Oil & Gas Corporation. During World War I, the company was a critical source of sulfur for the U.S. war effort. During World War II, the company operated at least twenty-seven Liberty Ships and was awarded a War Service Flag. In 1960, the company merged with the Texas Natural Gas Corporation to form the Union Texas Natural Gas Corporation. In 1962, Union Texas was acquired by Allied Chemical Corporat ...

Sulfur Mining In Sicily
Sulfur was one of Sicily's most important mineral resources, which is no longer exploited. The area covered by the large deposits is the central area of the island and lies between the provinces of Caltanissetta, Enna and Agrigento: The area is also known to geologists as the chalky-sulfur plateau. But the area of mining exploitation also extended as far as the Province of Palermo with the Lercara Friddi basin and the Province of Catania, of which a part of the Province of Enna was part until 1928; it is the one in which sulfur mining, processing and transport took place in the last quarter of the millennium. For a time it also represented the maximum production area worldwide. History The harvesting of outcrop sulfur took place even in very ancient times. In fact, mining vestiges have been found dating back to 200 B.C.E.; it was used in medicine from time immemorial but the Ancient Rome, Romans also used it for war purposes by mixing it with other fuels.

Frasch Process
The Frasch process is a method to extract sulfur from underground deposits by taking advantage of the low melting point of sulfur. It is the only industrial method of recovering sulfur from elemental deposits. Most of the world's sulfur was obtained this way until the late 20th century, when sulfur recovered from petroleum and gas sources became more commonplace (see Claus process). In the Frasch process, superheated water is pumped into the sulfur deposit; the sulfur melts and is extracted. The Frasch process is able to produce high-purity sulfur of about 99.5%. History In 1867, miners discovered sulfur in the caprock of a salt dome in Calcasieu Parish, Louisiana, but it was beneath quicksand, which prevented mining. In 1894 the German-born American chemist, Herman Frasch (1852–1914), devised his Frasch method of sulfur removal using pipes to bypass the quicksand. This replaced the inefficient and polluting Sicilian method. The process proved successful, on December 24 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freeport, Texas
Freeport is a city in Brazoria County, Texas, United States, located on the Gulf of Mexico, founded in 1912.

Freeport's economic growth began in 1939 with the construction of Dow Chemical Company facilities, which remain its largest employer and are the largest integrated chemical manufacturing facility in the United States. In 2002, Freeport LNG was founded; an LNG export terminal was developed in the early 2010s after the US shale gas revolution and came online in 2019. In June 2022 a pipeline rupture and explosion closed the terminal until February 2023. History Freeport was founded as a European-American settlement in November 1912 by the Freeport Sulphur Company.

Salt Dome
A salt dome is a type of structural dome formed when salt (or other evaporite minerals) intrudes into overlying rocks in a process known as diapirism. Salt domes can have unique surface and subsurface structures, and they can be discovered using techniques such as seismic reflection. They are important in petroleum geology as they can function as petroleum traps. Formation Diagram showing formation of salt domes Stratigraphically, salt basins developed periodically from the Proterozoic to the Neogene. The formation of a salt dome begins with the deposition of salt in a restricted basin. In these basins, the outflow of water exceeds inflow. Specifically, the basin loses water through evaporation, resulting in the precipitation and deposition of salt. While the rate of sedimentation of salt is significantly larger than the rate of sedimentation of clastics, it is recognized that a single evaporation event is rarely enough to produce the vast quantities of salt needed to f ...

Sulfur
Sulfur ( American spelling and the preferred IUPAC name) or sulphur ( Commonwealth spelling) is a chemical element; it has symbol S and atomic number 16. It is abundant, multivalent and nonmetallic. Under normal conditions, sulfur atoms form cyclic octatomic molecules with the chemical formula S8. Elemental sulfur is a bright yellow, crystalline solid at room temperature. Sulfur is the tenth most abundant element by mass in the universe and the fifth most common on Earth. Though sometimes found in pure, native form, sulfur on Earth usually occurs as sulfide and sulfate minerals. Being abundant in native form, sulfur was known in ancient times, being mentioned for its uses in ancient India, ancient Greece, China, and ancient Egypt. Historically and in literature sulfur is also called brimstone, which means "burning stone". Almost all elemental sulfur is produced as a byproduct of removing sulfur-containing contaminants from natural gas and petroleum.. Downloahere Th ...
