Title (EN) OIL COAGULANT PRODUCTS AND METHOD OF USE THEREFOR
(FR) PRODUITS COAGULANT LE PETROLE ET PROCEDE D'UTILISATION DESDITS PRODUITS
Abstract:
(EN) Oil coagulant compositions and methods of using them to coagulate oil that has been spilled on water are prepared from a thermal reaction utilizing an oil component such as glycerides (e.g. linseed oil), fatty acids, alkenes or alkynes and a polymer component, such as polyisobutylmethacrylate. The oil coagulant composition floats on the water surface and coagulates oil independent of both agitation and temperature, and can be used in both salt and fresh water. After the coagulant has coagulated the spilled oil, the floating coagulated oil, at least 99.9 %, can be readily removed from the water mechanically. An alternative way of using the composition is to use it to impregnate a porous substrate, preferably floatable, which is then applied to spilled oil.
(FR) Composition coagulant le pétrole et procédés d'utilisation desdites compositions pour faire coaguler du pétrole qui a été déversé sur un plan d'eau. Lesdites compositions sont préparées sur la base d'une réaction thermique faisant appel à un constituant huileux tel que les glycérides (par ex. huile de lin), les acides gras, les alcènes ou les alkynes et à un constituant polymère tel que le polyisobutylméthacrylate. Ladite composition flotte sur la surface de l'eau et coagule le pétrole indépendamment de l'agitation et de la température, et peut être utilisée dans des eaux tant douces que salées. Une fois le pétrole déversé coagulé par le coagulant, il est facile d'enlever mécaniquement de l'eau le pétrole flottant coagulé, à raison d'au moins 99,9 %. Alternativement, on peut utiliser ladite composition pour imprégner un substrat poreux, de préférence flottant, qui est ensuite appliqué sur le pétrole déversé.
