Abstract

Material to fight oil pollution made of graminaceous (plant) material which has been dehydrated by roasting, and can float on water. It is treated by washing with blown air, ventilation and then roasting, to obtain a blackened color demonstrating complete dehydration without destroying the graminates. The graminaceous material is between 0.1 mm<3> and 10 mm<3> in size and contains a mixture of graminates.

Description

<Desc/Clms Page number 1> <Desc / Clms Page number 1>

La présente invention concerne une utilisation de graminées, pour la prévention, et la lutte contre la pollution des produits gras, et en particulier, des hydrocarbures et de ses dérivés bruts ou transformés, en milieu aqueux, tel que les mers, les océans, les rivières, les étangs, les bassins de retenu, et bien d'autres. Elle permet à la fois de résoudre leur dispersion, et leur Adhésion sur tous les supports minéraux naturels ainsi que sur les animaux dans leur ensemble, en particulier les animaux à plumes ou poils. Cette invention est mélangée aux pollutions, elle permet aux animaux qui entre en contact avec la pollution de ne pas être recouvert sur leur partie physique du corps de cette dite pollution. Cette invention permet aux pollutions d'être traitées avant qu'elle ne trouve une destination finale sur des rivages ou autres lieux souvent inconnus dus aux changements climatiques, cette invention permet de faire flotter la pollution en surface afin d'être plus facilement récoltée. The present invention relates to a use of grasses, for the prevention and the fight against the pollution of fatty products, and in particular, of hydrocarbons and its crude or processed derivatives, in aqueous medium, such as seas, oceans, rivers, ponds, retention ponds, and many more. It makes it possible both to resolve their dispersion and their adhesion to all natural mineral supports as well as to animals as a whole, in particular animals with feathers or hair. This invention is mixed with pollution, it allows animals which come into contact with pollution not to be covered on their physical part of the body with this so-called pollution. This invention allows pollution to be treated before it finds a final destination on shores or other places often unknown due to climate change, this invention allows pollution to float on the surface in order to be more easily collected.

Cette présente invention permet de protéger de la pollution car elle rassemble la pollution en aggloméré mou indépendant, de ce qui pourraient rentrer en contact avec la pollution ellemême ou, bien que la pollution puisse recouvrir par effet des forces naturelles de la nature, tel que le flux ou le reflux des marées, le vent et toutes autres conditions climatiques. This present invention makes it possible to protect from pollution because it gathers the pollution in independent soft agglomerate, of what could come into contact with the pollution itself or, although the pollution can cover by effect of the natural forces of nature, such as the ebb or flow of tides, wind and all other climatic conditions.

Les pollutions des hydrocarbures en milieu liquide sont souvent combattues par des produits dispersants ou, chimique. Oil pollution in a liquid medium is often combated by dispersants or chemicals.

Les produits utilisés protège l'adhérence de la pollution sur les minéraux, uniquement s'ils sont tout recouvert, avant que la pollution arrive sur le lieu traité, et si la pollution ne se dirige pas ailleurs. The products used protect the adhesion of pollution on the minerals, only if they are completely covered, before the pollution arrives at the treated place, and if the pollution does not go elsewhere.

Les produits utilisés ne permettent pas toujours la flottaison des pollutions traitées, et de plus n'offre pas de sécurité pour les matières minérale sur lesquelles ces pollution se déposent. The products used do not always allow the flotation of the pollution treated, and moreover do not offer safety for the mineral matter on which this pollution is deposited.

Aucun produit ne permet une protection des animaux avant leur contact avec la pollution seul des machines existe pour les nettoyer après qu'ils ont été en contact avec une pollution. No product protects animals before they come into contact with pollution, only machines exist to clean them after they have been in contact with pollution.

Le produit selon l'invention permet de remédier à cet inconvénient. The product according to the invention overcomes this drawback.

Il est constitué par des graminées ayant subi un traitement de torréfaction afin de les déshydratés et étant susceptible de flotter en milieu aqueux, et en particulier dans l'eau de mer. It is made up of grasses which have undergone a roasting treatment in order to dehydrate them and are capable of floating in an aqueous medium, and in particular in sea water.

Les dimensions des dites graminées sont préférentiellement comprises entre 0.1 et 10 mm3
Leur pouvoir de rassembler la pollution par hydrocarbure est rapide, elle peut être accélérée par les forces naturelles tel que le vent et les flux et reflux. The dimensions of said grasses are preferably between 0.1 and 10 mm3
Their power to collect oil pollution is rapid, it can be accelerated by natural forces such as wind and ebb and flow.

Elle est facile d'utilisation, naturel, ce qui lui donne faculté de ce détruire biodégradablement. L'invention permet à la pollution ou qu'elle se dirige de ne pas adhérer à un support minéral, dés son arrivée, sans avoir eu besoin de traiter auparavant le minéral. Les animaux qui rentreront en contact avec la pollution ne serraient pas recouvert de la dite pollution du fait que sa nouvelle texture n'adhérerait pas sur la partie physique de l'animal en question. It is easy to use, natural, which gives it the ability to destroy biodegradably. The invention allows the pollution or that it is directed not to adhere to a mineral support, as soon as it arrives, without needing to treat the mineral beforehand. The animals which will come into contact with the pollution would not be covered with the said pollution because its new texture would not adhere to the physical part of the animal in question.

graminées, celles-ci sont soumises à un procédé global de traitement qui consistes-en : - un lavage des graminées par air pulsé sous pression. In order to improve the absorption qualities of petroleum product derivatives by these
Figure img00010001

grasses, these are subjected to a global treatment process which consists of: - washing of the grasses by pulsed air under pressure.

- une torréfaction des graminées jusqu'à obtention d'une couleur noirâtre en fin de traitement. - roasting the grasses until a blackish color is obtained at the end of treatment.

- selon une variante non illustrée le temps de cuisson est différent, selon la nature et la taille des dites graminées. - According to a variant not shown, the cooking time is different, depending on the nature and size of said grasses.

L'essentiel étant d'aboutir à une déshydratation aussi parfaite que possible, sans destruction du produit. The main thing is to achieve as perfect dehydration as possible, without destroying the product.

A titre d'exemple non limitatif le produit peut être utilisé lors de l'échouage d'un bateau transportant du produit pétrolifère. (Test effectué en laboratoire au CEDRE de Brest) By way of non-limiting example, the product can be used during the grounding of a boat carrying petroleum product. (Test carried out in the laboratory at CEDRE in Brest)
