Chemical Industry
The chemical industry comprises the companies and other organizations that develop and produce industrial, specialty and other chemicals. Central to the modern world economy, the chemical industry converts raw materials ( oil, natural gas, air, water, metals, and minerals) into commodity chemicals for industrial and consumer products. It includes industries for petrochemicals such as polymers for plastics and synthetic fibers; inorganic chemicals such as acids and alkalis; agricultural chemicals such as fertilizers, pesticides and herbicides; and other categories such as industrial gases, speciality chemicals and pharmaceuticals. 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 Revo ...

Commodity Chemicals
Commodity chemicals (or bulk commodities or bulk chemicals) are a group of chemicals that are made on a very large scale to satisfy global markets. The average prices of commodity chemicals are regularly published in the chemical trade magazines and web sites such aChemical WeekanICIS There have been several studies of the scale and complexity of this market for example in the USA. Commodity chemicals are a sub-sector of the chemical industry (other sub sectors are fine chemicals, specialty chemicals, inorganic chemicals, petrochemicals, pharmaceuticals, renewable energy (e.g. biofuels) and materials (e.g. biopolymers)). Commodity chemicals are differentiated primarily by the bulk of their manufacture. Types Chemical compounds are often classified into two classes, inorganic and organic. Inorganic chemicals * aluminium sulfate * ammonia * ammonium nitrate * ammonium sulfate * carbon black * chlorine * diammonium phosphate * monoammonium phosphate * hydrochloric acid * ...

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 order (United States), 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 U.S. state, state authorities. The governor of the state in which the disaster occurs must declare a state of emergency and formally request from the President of the United States, president that FEMA and the Federal government of the United States, 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 Oklahoma City bombing, bombing of the Alfred ...

Acid
An acid is a molecule or ion capable of either donating a proton (i.e. Hydron, hydrogen cation, H+), known as a Brønsted–Lowry acid–base theory, Brønsted–Lowry acid, or forming a covalent bond with an electron pair, known as a Lewis acid. The first category of acids are the proton donors, or Brønsted–Lowry acid–base theory, Brønsted–Lowry acids. In the special case of aqueous solutions, proton donors form the hydronium ion H3O+ and are known as Acid–base reaction#Arrhenius theory, Arrhenius acids. Johannes Nicolaus Brønsted, Brønsted and Martin Lowry, Lowry generalized the Arrhenius theory to include non-aqueous solvents. A Brønsted–Lowry or Arrhenius acid usually contains a hydrogen atom bonded to a chemical structure that is still energetically favorable after loss of H+. Aqueous Arrhenius acids have characteristic properties that provide a practical description of an acid. Acids form aqueous solutions with a sour taste, can turn blue litmus red, and ...

Samuel Garbett
Samuel Garbett (1717– 5 December 1803R. H. Campbell, ‘Garbett, Samuel (1717–1803)’, Oxford Dictionary of National Biography, Oxford University Press, 200accessed 29 July 2012/ref>) was a prominent citizen of Birmingham England, during the Industrial Revolution, and a friend of Matthew Boulton. Historian Carl Chinn argues that he: Garbett's education extended: Garbett was employed by a London merchant named Hollis, as his agent for purchasing goods in Birmingham. In that role, he came: He married Anne Clay (d. 1772) of Aston in August 1735. He then made his fortune as a merchant in his own right, before entering partnership with Dr John Roebuck to set up a laboratory in Steelhouse Lane where precious metals were refined and assay An assay is an investigative (analytic) procedure in laboratory medicine, mining, pharmacology, environmental biology and molecular biology for qualitatively assessing or quantitatively measuring the presence, amount, or fu ...

John Roebuck
John Roebuck of Kinneil FRS FRSE (1718 – 17 July 1794) was an English industrialist, inventor, mechanical engineer, and physician who played an important role in the Industrial Revolution and who is known for developing the industrial-scale manufacture of sulphuric acid. Life and work John Roebuck was born in Sheffield, where his father, also John Roebuck, had a prosperous manufacturing business. After attending Sheffield Grammar School and Dr. Philip Doddridge's academy at Northampton, Roebuck studied medicine at Edinburgh, where he developed a taste for chemistry from the lectures of William Cullen and Joseph Black. He finally graduated M.D. at the University of Leiden in 1742. Roebuck started medical practice at Birmingham, but devoted much of his time to chemistry, especially its practical applications. Among the most important of his early achievements in this field was the introduction, in 1746, of leaden condensing chambers for the manufacture of sulphur ...

Joshua Ward
Joshua Ward (1685–1761) was an English doctor, most remembered for the invention of Friar's Balsam. He sat briefly in the House of Commons from 1715 to 1717. Life Ward was born in Yorkshire. He was the brother of John Ward, who was MP for several years. At the 1715 general election Ward was returned as Member of Parliament for Marlborough, through the artifice of one of the mayors, but was unseated on petition in 1717. Ward went to France where he practiced as a quack doctor, but returned to London in 1734. He invented a medicine called "Joshua Ward's drop", also known as the "Pill and Drop". It was supposed to cure people of any illness they had, gaining acclaim and notoriety for Ward. Ward is widely cited as an example of a quack. His pills, which he claimed could cure any illness, are suspected of containing large amounts of antimony, which is poisonous and could cause permanent liver damage. The pills were artificially coloured red, purple and blue. The historian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sulfuric Acid
Sulfuric acid (American spelling and the preferred IUPAC name) or sulphuric acid (English in the Commonwealth of Nations, Commonwealth spelling), known in antiquity as oil of vitriol, is a mineral acid composed of the elements sulfur, oxygen, and hydrogen, with the molecular formula . It is a colorless, odorless, and Viscosity, viscous liquid that is Miscibility, miscible with water. Pure sulfuric acid does not occur naturally due to its Dehydration reaction, strong affinity to water vapor; it is Hygroscopy, hygroscopic and readily absorbs water vapor from the Atmosphere of Earth, air. Concentrated sulfuric acid is a strong oxidant with powerful dehydrating properties, making it highly corrosive towards other materials, from rocks to metals. Phosphorus pentoxide is a notable exception in that it is not dehydrated by sulfuric acid but, to the contrary, dehydrates sulfuric acid to sulfur trioxide. Upon addition of sulfuric acid to water, a considerable amount of heat is releas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Industrial Revolution
The Industrial Revolution, sometimes divided into the First Industrial Revolution and Second Industrial Revolution, was a transitional period of the global economy toward more widespread, efficient and stable manufacturing processes, succeeding the Second Agricultural Revolution. Beginning in Kingdom of Great Britain, Great Britain around 1760, the Industrial Revolution had spread to continental Europe and the United States by about 1840. This transition included going from craft production, hand production methods to machines; new Chemical industry, chemical manufacturing and Puddling (metallurgy), iron production processes; the increasing use of Hydropower, water power and Steam engine, steam power; the development of machine tools; and rise of the mechanisation, mechanised factory system.

Pharmaceutical Industry
The pharmaceutical industry is a medical industry that discovers, develops, produces, and markets pharmaceutical goods such as medications and medical devices. Medications are then administered to (or self-administered by) patients for curing or preventing disease or for alleviating symptoms of illness or injury. Pharmaceutical companies may deal in generic drugs, branded drugs, or both, in different contexts. Generic materials are without the involvement of intellectual property, whereas branded materials are protected by chemical patents. The industry's various subdivisions include distinct areas, such as manufacturing biologics and total synthesis. The industry is subject to a variety of laws and regulations that govern the patenting, efficacy testing, safety evaluation, and marketing of these drugs. The global pharmaceutical market produced treatments worth a total of $1,228.45 billion in 2020. The sector showed a compound annual growth rate (CAGR) of 1.8% in 2021, ...
