It develops and builds apparatus for the processes involving the transfer of heat in the petrochemical, chemical and metallurgical industries, e.g. cracked gas coolers for the manufacture of ethylene, gas coolers for the manufacture of methanol, ammonia and hydrogen and a multitude of equipment for special purposes. The company continues to be ...
Drawing the retorts at the Great Gas Establishment Brick Lane, from The Monthly Magazine (1821). The history of gaseous fuel, important for lighting, heating, and cooking purposes throughout most of the 19th century and the first half of the 20th century, began with the development of analytical and pneumatic chemistry in the 18th century.
A drawing and detailed description of Melville's Improved Gas Apparatus, presumably reflecting the 1813 patent, may be seen in an 1814 letter from Benjamin Silliman, Professor of Chemistry at Yale College, to David Melville, Patentee of the Improved Gas Apparatus, as recorded in The Journal of Foreign Medical Science and Literature. Likewise ...
Ethylene (IUPAC name: ethene) is a hydrocarbon which has the formula C 2 H 4 or H 2 C=CH 2.It is a colourless, flammable gas with a faint "sweet and musky" odour when pure. [7] It is the simplest alkene (a hydrocarbon with carbon–carbon double bonds).
Thomas Midgley Jr. (May 18, 1889 – November 2, 1944) was an American mechanical and chemical engineer.He played a major role in developing leaded gasoline (tetraethyl lead) and some of the first chlorofluorocarbons (CFCs), better known in the United States by the brand name Freon; both products were later banned from common use due to their harmful impact on human health and the environment.
In 1892, after working on this idea for several years, he considered his theory to be completed. In the same year, Diesel was given the German patent DRP 67207. [ 12 ] In 1893, he published a treatise entitled Theory and Construction of a Rational Heat-engine to Replace the Steam Engine and The Combustion Engines Known Today , that he had been ...
An ethylene plant, once running, does not need to import steam to drive its steam turbines. A typical world scale ethylene plant (about 1.5 billion pounds (680 KTA) of ethylene per year) uses a 45,000 horsepower (34,000 kW) cracked gas compressor, a 30,000 hp (22,000 kW) propylene compressor, and a 15,000 hp (11,000 kW) ethylene compressor.
1823: The concept of a gas vacuum engine is patented by British engineer Samuel Brown. One of Brown's engines was used to pump water at a canal in London from 1830 to 1836. 1824: The Carnot cycle – a thermodynamic theory for heat engines – is published in a research paper by French physicist Nicolas Léonard Sadi Carnot.
