Record 2 2007-03-27

English

Subject field(s)
  • Coal Gasification
  • Energy Transformation
DEF

A process that uses an inert heavy liquid with a specific gravity between that of coal and free mineral matter to separate coarse or fine-size coal in a static bath or cyclone separator.

CONT

By running finely ground coal through a chemical bath(currently pentane, a hydrocarbon similar to butane), the Otisca process separates out all but 1% of the mineral content, or ash, and 0. 5% of the sulfur that forms sulfur oxides when it burns.

French

Domaine(s)
  • Gazéification des charbons
  • Transformation de l'énergie
CONT

Le procédé Otisca, développé par Otisca Corp. aux États-Unis, utilise le pentane comme agent de séparation.

Record 3 2005-11-09

English

Subject field(s)
  • Black Products (Petroleum)
DEF

A special grade of gas-oil with an extra-low sulfur content, used as a fuel for [diesel engine road] vehicles.

OBS

Derv: An acronym for diesel engine road vehicle which is now commonly used to refer to a high quality automatic diesel fuel rather than the vehicle itself.

French

Domaine(s)
  • Produits noirs (Pétrole)
DEF

Carburant pour les véhicules Diesel.

OBS

gasoil : Cette graphie, puisée des Rectifications de l'orthographe recommandées par le Conseil supérieur de la langue française, est attestée dans le Petit Robert (2004).

Record 4 2005-08-03

English

Subject field(s)
  • Crude Oil and Petroleum Products
DEF

Crude oil having a high proportion of viscous, high-molecular-weight hydrocarbons, and often having a high sulfur content.

OBS

Crude oils are often referred to as heavy crudes or light crudes, according to their API gravities, the lighter oils having higher API gravities.

OBS

heavy crude oil: Source: Petroleum and Gas Revenue Tax Act.

French

Domaine(s)
  • Pétroles bruts et dérivés
DEF

Terme désignant généralement un pétrole brut de densité supérieure à 900 kg/m3.

CONT

Une analyse préliminaire, en laboratoire, permet de déterminer la quantité et la qualité de produits finis que l'on peut attendre du pétrole brut étudié : un brut «léger», c'est-à-dire de faible densité, produira plus d'essences, un brut «lourd» plus de fuels ou de bitumes.

OBS

pétrole lourd brut : Source : Loi de l'impôt sur les revenus pétroliers.

  • Petrochemistry
DEF

The sulphur in the fuel expressed as a percentage by weight.

CONT

Crude oil is customarily described in terms of its gravity, base, color, and sulfur content.

CONT

Sulphide facies. ... This facies ... formed under anaerobic conditions. Its high sulphur content precludes its exploitation as an iron ore. It has ... been mined for its sulphur content ... in Czechoslovakia.

  • Metals Treatment
  • Petrochemistry
DEF

A material for reducing the sulfur content of cast iron or steel in the cupola or smelter.

OBS

desulfurize; desulfur: to remove sulfur or sulfur compounds from (as molten metals or petroleum oils) by suitable agents.

French

Domaine(s)
  • Chimie
  • Traitements des métaux
  • Chimie du pétrole
DEF

Substance propre à provoquer la désulfuration.

OBS

Record 7 1993-03-25

English

Subject field(s)
  • Pulp Preparation (papermaking)
OBS

Because of significant advantages, the kraft process has become established as the world's dominant pulping method. Nonetheless, the process also has some severe shortcomings, principally the low yield from wood, the comparatively high residual lignin content of bleachable grades, and the malodors caused by reduced sulfur compounds.... Most of the earlier modifications were aimed at increased retention of carbohydrates by stabilizing the end groups of the cellulose and hemicellulose polymer chains against "peeling reactions". These reactions cause dissolution of the end groups one unit at a time and consume a significant portion of the cooking chemical.

French

Domaine(s)
  • Préparation de la pâte à papier
OBS

La place prédominante qu'occupe le procédé kraft parmi les méthodes de mise en pâte utilisées dans le monde témoigne bien du nombre d'avantages marqués qu'il offre. Le procédé comporte néanmoins de graves inconvénients dont les principaux sont un faible rendement du bois et les mauvaises odeurs causées par les composés de soufre réduits. (...) La plupart des modifications proposées visent l'obtention d'une meilleure rétention des hydrates de carbone par une stabilisation des monomères de bouts de chaîne des polymères de la cellulose et des hémicelluloses afin d'éviter leur départ. Cette réaction qui consiste en une dissolution successive des monomères de bouts de chaîne consomme une part importante du réactif de cuisson.
