The invention discloses methods of making oil coagulant compositions, the oil coagulants made thereby and processes for using the coagulants to coagulate oil that has been spilled on water. The coagulant comprises a glyceride, such as, for example, the drying oil linseed oil, a polymer, such as, for example, poly(isobutylmethacrylate), and a solvent, such as, for example, 2,2,4-trimethyl-1, 3-pentanediol monoisobutyrate. The coagulant of the present invention coagulates oil independent of both agitation and temperature, and may be used in both salt and fresh water. After the coagulant has coagulated the spilled oil, the coagulated oil may be readily mechanically removed from the water such that at least 99.9 % of the oil is removed from the water and only a faint trace of oil remains in the water.
Procédés de fabrication de compositions coagulant du pétrole, coagulants de pétrole ainsi obtenus et procédés d'utilisation desdits coagulants pour coaguler du pétrole qui s'est répandu sur l'eau. Ledit coagulant comporte un glycéride tel que, par exemple, de l'huile de lin qui est une huile siccative, un polymère tel que, par exemple, du méthacrylate polyisobutylique et un solvant tel que, par exemple, 2,2-4-triméthyle-1 ou monoisobutyrate de 3-pentanediol. Le coagulant de la présente invention coagule du pétrole indépendamment de l'agitation et de la température, et peut être utilisé à la fois dans l'eau salée et dans l'eau douce. Une fois que le coagulant a coagulé le pétrole répandu, au moins 99,9 % du pétrole coagulé peut être éliminé mécaniquement et facilement de l'eau et il ne reste dans l'eau que de faibles traces de pétrole.
