English

Subject field(s)
  • Natural Gas and Derivatives
CONT

The term "unconventional gas" applies to natural gas from coal seams, tight gas sands, gas shales and gas hydrates.... Canada's CBM [coalbed methane] reserves are estimated to be about 60 trillion cubic feet(Tcf), with over 20 Tcf in Alberta.... For comparison, the total production of conventional natural gas in Alberta to date is over 100 Tcf and the remaining conventional natural gas reserves are slightly over 40 Tcf.

French

Domaine(s)
  • Gaz naturel et dérivés
CONT

[...] contrairement à l'Alberta, dont les réserves conventionnelles de gaz naturel déclinent déjà, les ressources hydroélectriques québécoises sont renouvelables et pourraient donc générer une rente collective relativement inépuisable.

CONT

Papier blanchi sans chlore, vendu souvent comme papier bio ou éco. Cette appellation peut signifier beaucoup de choses : La cellulose peut être blanchie avec des composés chlorés au lieu de chlore [...] ou avec de l'oxygène. Les abréviations ECF et TCF indiquent plus exactement le processus de production du papier. ECF = «elementary chlorine free» = sans chlore élémentaire = blanchi avec des composés chlorés. TCF = «totally chlorine free» = totalement sans chlore = blanchi à l'oxygène.

Peroxide brightening stages have been used for many years in mechanical pulp mills and has recently gained acceptance in kraft pulp mills. It has been used to replace chlorine dioxide brightening stages in applications where very low AOX or TCF pulps are required. For chemical pulps typical peroxide stage conditions are temperatures of 80-90°C, pHs over 10. 8 and retention times over 3h. It is important to maintain a high concentration of peroxide through the stage to reach the desired brightness.

French

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

Les stades d'éclaircissement au peroxyde sont utilisés depuis de nombreuses années par les usines de pâte mécanique et ont récemment pénétrés les usines kraft. Le peroxyde remplace le bioxyde de chlore lors des derniers stades de blanchiment afin d'abaisser les rejets de COA ou pour permettre la production de pâte SC. Pour les pâtes chimiques, les conditions usuelles sont : une température de 80-90 °C; un pH supérieur à 10.8; et un temps de résidence de plus de trois heures.

... stage... used to delignify pulps to very low Kappa numbers normally in a TCF bleaching sequence. Due to the very fast reaction rate and the large amount of oxygen gas present mixing is very important.

[...] stade [...] employé, habituellement dans les séquences SC, pour délignifier les pâtes jusqu'à de très faibles indices kappa. Le mélange de la pâte et du gaz est un facteur important parce que la vitesse de réaction de l'ozone est très élevée et sa concentration dans l'oxygène relativement faible. L'ozonation est effectuée normalement à une température de 50-60 °C, à un pH entre 2 et 4 et un temps de résidence de quelques minutes. L'ozone peut également être associée au bioxyde de chlore dans un stade combiné (DZ).

Subject field(s)
  • Chemical Elements and Compounds
  • Pulp Preparation (papermaking)
DEF

peroxyacids : Oxidative bleaching agents which can be used to delignify and brighten chemical pulps and to activate peroxide brightening stages. Increased study and evaluation in laboratories and mills have resulted primarily from the search for TCF bleaching alternatives. Peroxyformic acid has been evaluated in Finland(MILOX process).

CONT

The peroxyacids of most current interest are monopersulphuric acid(Caro's Acid) and peroxyacetic acid. They have been demonstrated to increase the brightness ceiling and strength of TCF chemical pulps.

CONT

Peroxyacids are classified by the presence of the peroxide group. X-OO-Y, X-N-Y contain species that ionize to a proton.

French

Domaine(s)

DEF

CONT

L'acide peracétique [...], l'acide persulfurique de Caro [...], sont des peroxyacides. Dérivés de l'eau oxygénée, les peroxyacides sont rarement assez stables pour être isolés; ils ont des propriétés voisines de celles de l'eau oxygénée.

CONT

[Les] peroxyacides [sont employés] pour délignifier et blanchir les pâtes chimiques ainsi que pour activer les stades de blanchiment au peroxyde.

English

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

A treatment, most often SO2, but in some cases H2SO4 or HCl, applied a) After a final chlorine dioxide, hyprochlorite or peroxide stage to destroy residual bleaching agent and remove metal ions which prevents brightness loss and avoids fibre degradation, and to create a pH favourable for brightness stability(alkaline pulps tend to yellow on exposure to light and air) ;b) As a pretreatment before an oxygen stage, which tends to improve both brightness and physical strength, probably by removing metal ions from pulp; and c) Between stages, such as peroxide-hydrosulphite, to eliminate the washing steps by creating acid conditions necessary for the hydrosulphite stage, and to destroy residual peroxide by reduction which would otherwise consume costly hydrosulphite; d) Has been used in place of a chelation stage in a TCF sequence with peroxide. In this application the PH is very important.

OBS

SO2 and H2SO4 should be read: SO2 and H2SO4.

French

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

Traitement pour lequel le SO2 est le plus souvent utilisé. Dans certains cas, on utilise également le H2SO4 ou le HCl. a) Utilisé en fin de séquence, après un traitement au bioxyde de chlore, à l'hypochlorite ou au peroxyde, il permet de détruire les résidus d'agents de blanchiment et d'enlever les ions métalliques. Ce traitement prévient la perte de blancheur (jaunissement) et la dégradation des fibres. Bref, un pH favorable à la stabilité de la blancheur est obtenu (les pâtes alcalines ont tendance à jaunir sous l'action de la lumière et de l'air). b) Utilisé comme prétraitement avant un traitement à l'oxygène ou un stade de peroxyde d'hydrogène, il permet d'améliorer à la fois la blancheur et les propriétés physiques, en solubilisant les métaux de transition. c) Entre deux stades tel que peroxyde et hydrosulfite, il permet d'éliminer l'étape de lavage en créant les conditions acidiques nécessaires à un traitement à l'hydrosulfite, et de détruire (par réduction) le peroxyde résiduaire, qui autrement consommerait l'hydrosulfite.

OBS

Dans le texte qui précède, on doit lire : SO2 ainsi que H2SO4.
