  • Missiles and Rockets

  • Launchers (Astronautics)
DEF

A rocket propellant consisting of a single substance, especially a liquid, capable of creating rocket thrust without the addition of a second substance.

CONT

A monopropellant is a chemical propulsion fuel which does not require a separate oxidizer. A rocket engine which is based on a monopropellant requires only one fuel line instead of a fuel and an oxidizer line. The "mono" in monopropellant means singular - a fuel that can function alone. A chemical propulsion system that combines like hydrogen and oxygen would be a bipropellant. A monopropellant burns by itself because the oxidizer is bound into the molecule itself. This makes the rocket engine lighter, less expensive, and more reliable. Monopropellant designs are typically used in control thrusters but not in actual propulsion units.

CONT

The most commonly used monopropellant is hydrazine(N2H4), a chemical which is characterized as "strongly reducing". The most common catalyst is granular alumina coated with iridium(aka. Shell-405). There is no igniter with hydrazine. Shell 405 is a spontaneous catalyst, that is, hydrazine decomposes on contact with the catalyst. The reaction is highly exothermic and produces an 1800°F(1000°C) gas that is a mixture of nitrogen, hydrogen and ammonia. Another monopropellant is hydrogen peroxide, which, when purified to 90% or higher concentration, is self-decomposing at high temperatures or when a catalyst is present.

Subject field(s)
  • Petroleum Distillation
CONT

The Shell Middle Distillate Synthesis(SMDS) plant now operational at Bintulu, Malaysia, is the latest in a series of partnership projects between Shell companies and the people of Malaysia that stretches back for more than 100 years. The new plant uses advanced technology to convert natural gas, abundantly available from the Central Luconia field offshore Sarawak, into liquid fuels of high purity. These fuels can also be used as components to upgrade lower quality stock derived from conventional crude oil processing. In addition, the plant can produce high-value waxes, as well as feedstocks for detergents and lubricants. The product mix can be varied to meet market needs. The SMDS technology was developed at the Shell laboratory in Amsterdam(KSLA) over a period of 20 years. After commercial and technical assessment, Bintulu was chosen in preference to sites in other parts of the world as an appropriate location for the employment of SMDS technology in the first commercial plant.

CONT

February 2003, Royal Dutch Shell(Netherlands) announced its plans to build two GTL facilities with a combined capacity of 75 000 bbls/d. QP is looking to employ Shell' s middle distillates synthesis(SDMS) technology to convert gas into diesel and kerosene.

  • Environmental Studies and Analyses
CONT

SPI, or Sediment Profile Imagery, is an innovative and cost efficient method of surveying and/or monitoring lake or marine aquatic environments with a view to establishing the environmental status of these habitats or as part of a site suitability study.... SPI is based on single lens reflex(SLR) camera photography and computer-based image analysis which greatly accelerates the time required to write reports and provide relevant data to the client/legislator in a matter of weeks. SPI technology can readily quantify over 20 physical, chemical and biological parameters including : sediment grain size; prism penetration; surface pelletal layer; sediment surface relief; mud clasts; redox area; redox contrast; current apparent redox boundary; relict redox boundaries; methane gas vesicles; apparent faunal dominants; voids; burrows; surface features(e. g. worm tubes, epifauna, shell) ;dredged material; microbial aggregations; and successional stage.

Des photographies de profils sédimentaires obtenus de carottes prélevées à l'aide de carottiers en plexiglass Hargrave ont servi à mettre au point un moyen nouveau pour déterminer l'enrichissement en matières organiques. Des plongeurs autonomes prélèvent des carottes de sédiments pouvant aller jusqu'à 30 cm de longueur; une fois ramenées à la surface, les carottes sont photographiées, sous-échantillonnées et interprétées. L'interprétation repose sur la profondeur de discontinuité de l'oxydo-réduction et la présence ou l'absence d'organismes, de terriers et de vides, tels que révélés par les photographies numériques. On obtient ainsi un nombre intégré attribuable à l'indice d'enrichissement organique. M. Wildish a prouvé la justesse de cette méthode, appelée imagerie de profils sédimentaires (IPS), aux sites salmonicoles de la baie de Fundy et on prévoit aussi la mettre à l'essai à des installations semblables en Tasmanie (Australie).

CONT

Although carbon emissions have fallen since liberalisation of the UK’s electricity market, this was entirely fortuitous, in that a lower carbon fuel (gas) was cheaper than a high carbon fuel (coal).

  • Ovens, Furnaces and Boilers (Heating)
CONT

Steel boilers are fabricated into one assembly of a given size and rating, usually by welding. The heat exchange surface past the firebox usually is an assembly of vertical, horizontal, or slanted tubes. The tubes may be firetube(flue gas inside, heated fluid outside) or watertube(fluid inside). The tubes may be in one or more passes. As with cast-iron boilers, dry base, wet leg, or wet base design may be used. The majority of small steel heating boilers are of dry base, vertical firetube design. Larger boilers usually have horizontal or slanted tubes; both firetube and watertube designs are used. A popular design for medium and large steel boilers, is the Scotch, or Scotch Marine, which is characterized by having a central fluid-backed cylindrical firebox, surrounded by firetubes in one or more passes, all within the outer shell.... Steel boiler sizes range from approximately 14. 7 kW(150 mBh) to the largest boilers made.

OBS

The boiler heats the water for circulation through the system. It may be rectangular or square (occasionally even round) and made of steel or cast iron.

A method of blasting coal has been undercut, topcut, or sheared. Into one end of a seamless high-grade Mo-steel cylinder 2 to 3 inches in diameter and from 36 inches to 60 inches long is put a cartridge containing a mixture of potassium perchlorate and charcoal with an electric match. The other end is sealed by a metal disc weaker than the shell and held in place by a cap which has holes at about 45° to the axis of the cylinder. The cylinder is filled with liquid carbon dioxide at a pressure of 1, 000 pounds per square inch and inserted in the borehole with the cap holes pointing outward. The heating mixture is lit and raises the gas pressure so that the disc is sheared; the carbon dioxide escaping through the angular holes tends to hold the cylinder in place, break and push the coal forward.

L'abatage au gaz carbonique consiste à introduire dans un obus spécial du gaz carbonique liquide, puis à obtenir l'évaporation de celui-ci par une cartouche chauffante, jusqu'à cisaillement d'une pièce métallique qui permet au gaz de s'échapper de l'obus. La pression brise le massif. Le procédé appelé "Cardox" exige le havage. La manipulation des tubes qui doivent chaque fois être remplis au jour, le prix élevé de ses charges amorces qui n'ont jamais été fabriquées sur le continent (le Cardox est un brevet anglais) sont de sérieux inconvénients qui expliquent le recul et presque l'abandon du procédé dans les dernières années.
