The ammonia-soda process was first patented in 1838 by H. G. Dyar and J. Hemming, who carried it out on an experimental scale in Whitechapel.
The title of the album was inspired by Eric Woolfson's visit to Imperial Chemical Industries (ICI) in Billingham, England, where the first thing he saw was a street with miles of pipes, no people, no trees and a sign that said 'Ammonia Avenue'.
Arcjets are a form of electric propulsion for spacecraft, whereby an electrical discharge (arc) is created in a flow of propellant (typically hydrazine or ammonia).
The theory is that aerobic bacteria covering the surface of the porous live rock and sand convert harmful ammonia (from fish and invertebrate waste) into nitrites, then nitrates, which are much less harmful to the tank's inhabitants.
Another study demonstrates how racemic nicotine (mixture of S and R-enantiomers 1 in scheme 3) can be deracemized in a one-pot procedure involving a monoamine oxidase isolated from Aspergillus niger which is able to oxidize only the amine S-enantiomer to the imine 2 and involving an ammonia–borane reducing couple which can reduce the imine 2 back to the amine 1.
Ludwigshafen also refined "30-50 tons/day of crude oil...brought in from Brücksel, near Karlsruhe...to products including lube oils." About 2.5 miles away from Ludwigshafen, an Oppau plant produced fertilizer and up to "800 T/day nitrogen as ammonia and a considerable part of this was exported as liquid ammonia to Hochst, Wolfen and Bittefeld." A separate Oppau plant produced up to 60 T/day of urea.
One of the later (1991) successful gun fuels was a saturated solution of Ammonium perchlorate in Ammonia.
However, most petrochemical reactors are catalytic, and are responsible for most of industrial chemical production in the world, with extremely high-volume examples such as sulfuric acid, ammonia, reformate/BTEX (benzene, toluene, ethylbenzene and xylene) and alkylate gasoline blending stock.
For this reason, the Firestreak missile on ground test was cooled by Arcton and in flight by ammonia pumped through the missile from the parent aircraft.
(KPC), an integrated international oil company, is the parent company of the government's operations in the petroleum sector, and includes Kuwait Oil Company, which produced oil and gas; Kuwait National Petroleum Co., refining and domestic sales; Petrochemical Industries Co., producing ammonia and urea; Kuwait Foreign Petroleum Exploration Co., with several concessions in developing countries; Kuwait Oil Tanker Co.
Ramagundam unit was unique in terms of Urea and Ammonia production wherein coal gasification methodology was used - FCI Ramagundam (simultaneously with FCI Talcher) was the first fertilizer plant in India to use coal gasification technology besides being world's biggest coal gasification based fertilizer unit.
Préface de Stanislas Meunier— Gauthier-Villars et fils (1897)--- Determination of ammonia in the air, nitrogen absorption from the air by plants.
This constituted the first step in the development of the ammonia system of compounds, a concept which, owing to the later contributions of Edward C. Franklin and Charles A. Kraus, became an outstanding feature of American chemical achievement.
Hantzsch pyrrole synthesis, the chemical reaction of β-ketoesters with ammonia and α-haloketones to give substituted pyrroles
The mission included three spacewalks to remove and replace a materials processing experiment outside ESA’s Columbus module and return an empty ammonia tank assembly.
Total Kjeldahl Nitrogen or TKN is the sum of organic nitrogen, ammonia (NH3) and ammonium (NH4+) in the chemical analysis of soils.
Live sand, a term used in aquarism, is natural reef coral sand populated with millions of beneficial bacteria and organisms which aid in the dissolving of organic wastes like ammonia, nitrites and nitrates produced by larger organisms in saltwater aquariums.
Independently, Charles H. Townes, James P. Gordon, and H. J. Zeiger built the first ammonia maser at Columbia University in 1953.
pH 7.5-8.4 is ideal with an almost pristine (near 0 ppm) Ammonia and Ammonium Nitrite content, Ammonium Nitrate levels are controlled by water changes as needed to maintain these demanding levels.
Examples include the use of high doses of pyridoxine (vitamin B6) in some patients with homocystinuria to boost the activity of the residual cystathione synthase enzyme, administration of biotin to restore activity of several enzymes affected by deficiency of biotinidase, treatment with NTBC in Tyrosinemia to inhibit the production of succinylacetone which causes liver toxicity, and the use of sodium benzoate to decrease ammonia build-up in urea cycle disorders.
During fermentation, selected bacteria (coryneform bacteria) cultured with ammonia and carbohydrates from sugar beets, sugar cane, tapioca or molasses, excrete amino acids into the culture broth from where L-glutamate is isolated.
Claud E. Cleeton and Neal H. Williams, Electromagnetic Waves of 1.1 cm Wave-Length and the Absorption Spectrum of Ammonia, Lancaster, Pa., Lancaster press, inc., 1934.
The major imports of the port are crude and petroleum products, LPG, wood pulp, timber logs, finished fertilizers, liquid ammonia, phosphoric acid, other liquid chemicals, containerized cargo, etc.
The loose crusty scales may also be removed by soaking the afflicted bird's legs in soapy water mixed with diluted ammonia, and the encrusted areas scrubbed gently with a soft brush.
Charles A. Kraus measured the electrical conductance of metal ammonia solutions and in 1907 was the first to attribute it the electrons liberated from the metal.
•
Hamilton Cady in 1897 was the first to relate the ionizing properties of ammonia to that of water.
Wishing to develop a better process for the production of alkali than the Leblanc process, he joined in partnership with John Brunner, who also worked for Hutchinson, to improve the ammonia-soda process, building a factory for this purpose at Winnington.
However, the purification system did not have bacteriostatic or bactericidal properties and it was incapable of removing impurities such as lithium, alcohols, ammonia, strong acids and bases or inorganic substances like sodium, lead, iron, arsenic and nitrates.
