"Nouveaux produits industriels issus de la t'ourbe, leur procédé .-de fabrication, et leur application pour combattre l'entartrement et les corrosions des ohaudières"
La présente invention a pour objet principal de nouveaux produits industriels issus de la tourbe, et leur procédé de fa- brication; elle comprend en outre leur application spéciale pour combattre l'entartrement et les oorrosions des chaudières.
@
Parmi les nombreux produits qui ont été utilisés dans une telle application figure la tourbe, soit à l'état pur, soit en mélange avec de la soude; cependant, les résultats obtenus n'ont pas été satisfaisants, et l'emploi de la tourbe, pure ou en mélange avec de. la soude, ne s'est pas développé.
Les nouveaux produits industriels qui font l'objet principal de l'invention résultent du traitement de la tourbe à chaud, à une température voisine de l'ébullition, par une solu- tion de soude à un pour oent environ, qui donne naissance à une 'solution de corps dits humates de soude t cette solution est séparée de la partie non attaquée de la tourbe, par exemple par filtration.
Cette solution d'humates de soude présente de bonnes qualités antitartres; mais il est possible d'obtenir de meilleurs résultats encore en procédant de l'une des manières exposées ci-après :
1 - La solution d'humates de soude est traitée par un acide,minéral, tel que l'acide chlorhydrique par exemple, et à chaud. La proportion diacide à employer peut varier dans des limites assez étendues, et être, par exemple de 35 cm3 d'acide chlorhydrique à 18 Baumé pour un litre de la solution d'humates
<Desc/Clms Page number 2>
de soude précitée; la température de traitement peut également varier, mais elle est avantageusement de 80 à 90 .
Les acides humiques précipitent, et sont séparés par filtration.-On obtient ainsi un gel contenant environ 10 % d'acides humiques et 90 % d'eau.
Ce gel peut être utilisé directement, ou par dessication à basse température (inférieure à 60 ), être transformé en produit solide.
Les produits ainsi préparés ont, du point de vue anti- tartre et antioxygène, des propriétés au moins équivalentes à celles des extraits tannants; à poids égal d'extrait sec, ils peuvent remplacer les extraits tannants dans tous produits antitartres.
2 - La solution d'humates de soude obtenue comme précédem- ment indiqué n'a qu'une efficacité limitée sur les précipités de sulfate de chaux; en conséquence, l'invention prévoit ltad- dition, en mélange aux humates de soude, de carbonates ou de phosphates alcalins (de sodium, de potassium ou d'amonium).
Bien que les proportion des corps en mélange puissent varier considérablement, les dosages suivants sont indiqués à titre dtexemple particulièrement avantageux : - Solution d'humates de soude préparée comme décrit plus haut; quantité correspondante à 2 grammes dtextrait sec par mètre cube d'eau et par degré hydrotimétrique de dureté totale.
- Carbonate de soude :10 grammes par mètre cube d'eau et par degré hydrotimétrique de dureté permanente.
REVENDICATIONS
1 - Un procédé de traitement de la tourbe à chaud par une solution de soude, donnant une solution d'humates de soude.
2 - Un procédé de traitement de la solution d'humates de soude, obtenue selon le procédé revendiqué en 1, par un acide minéral, en vue de précipiter les acides humiques, recueillis sous forme de gel ou de produits solides et utilisables tels quels ou en mélange avec tous autres produits..

"New industrial products from peat, their manufacturing process, and their application to combat scaling and corrosions in boilers"
The main object of the present invention is new industrial products derived from peat, and their manufacturing process; it also includes their special application to combat scaling and oorrosions in boilers.
@
Among the many products which have been used in such an application is peat, either in the pure state or as a mixture with soda; however, the results obtained were not satisfactory, and the use of peat, pure or mixed with. soda, did not develop.
The new industrial products which are the main object of the invention result from the hot treatment of peat, at a temperature close to boiling, with a solution of sodium hydroxide at about one percent, which gives rise to a 'solution of substances called sodium humates t this solution is separated from the unattacked part of the peat, for example by filtration.
This solution of soda humates has good anti-scale qualities; but even better results can be obtained by doing one of the following ways:
1 - The sodium humates solution is treated with an acid, mineral, such as hydrochloric acid for example, and hot. The proportion of diacid to be used can vary within fairly wide limits, and be, for example, 35 cm3 of 18 Baumé hydrochloric acid for one liter of the humate solution
<Desc / Clms Page number 2>
of the aforementioned soda; the treatment temperature can also vary, but it is advantageously from 80 to 90.
The humic acids precipitate, and are separated by filtration. A gel is thus obtained containing about 10% of humic acids and 90% of water.
This gel can be used directly, or by drying at low temperature (below 60), to be transformed into a solid product.
The products thus prepared have, from the anti-tartar and antioxidant standpoint, properties at least equivalent to those of the tanning extracts; for equal weight of dry extract, they can replace tanning extracts in all scale inhibitors.
2 - The sodium humates solution obtained as previously indicated has only a limited effectiveness on lime sulphate precipitates; consequently, the invention provides for the addition, as a mixture with sodium humates, of alkaline carbonates or phosphates (of sodium, potassium or ammonium).
Although the proportions of the substances in mixture can vary considerably, the following dosages are given by way of particularly advantageous example: - solution of sodium humates prepared as described above; quantity corresponding to 2 grams of dry substance per cubic meter of water and per hydrotimetric degree of total hardness.
- Soda ash: 10 grams per cubic meter of water and per hydrotimetric degree of permanent hardness.
CLAIMS
1 - A process for the hot treatment of peat with a soda solution, giving a solution of soda humates.
2 - A process for treating the solution of sodium humates, obtained according to the process claimed in 1, with a mineral acid, with a view to precipitating the humic acids, collected in the form of a gel or of solid products and which can be used as such or mixed with all other products.
