    摘要： A method for controlling vertical migration of contaminants in an aquifer includes introduction of a solubilizing solution having a surfactant and an alcohol or other light co-solvent. The surfactant is selected to solubilize the contaminant. The alcohol or other solvent is selected to provide the microemulsion with a substantially neutral buoyance with respect to groundwater. The neutral buyoancy of the microemulsion prevents the normal downward movement which is typical of the solubilized dense non-aqueous phase liquid in surfactant-enhanced a quifer remediation. Thus, the risk that any significant amount of solubilized dense non-aqueous contaminants will migrate vertically can be controlled. The relative tendency for vertical migration may also be reduced by increasing the injection rate or injected fluid viscosity by adding polymer or reducing the well (120, 130) spacing.

    摘要： Oil coagulant compositions, and methods of using such compositions to coagulate the oil that has been spilled on water are prepared from a thermal reaction utilizing an oil component selected from the group consisting of glycrides, fatty acids, alkenes and alkynes, and a copolymer component. Representative polymers include, for example, isobutyl methacrylate polymers, and representative oil components include, for example, glycerides such as those derived from a drying oil such as linseed oil. The composition of the present invention 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 can be readily removed from the water by mechanical means 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. An alternate way of using the composition is to incorporate it into a porous substrate, which substrate is then applied to the spilled oil. Preferably, the porous substrate is a floatable material, enabling the product to keep afloat Group 5 oils or asphalt.

    摘要： A method for recuperating crude oil from the body of a spill. First, the body of the spill is sprayed at low pressure then the same operation is done at a relatively higher pressure of at least 100 psi. After the dispersant is allowed to penetrate the body o f the spill for several hours, physical agitation of the body of the spill is induced by the use of air compressors operating in the range between 500 and 700 psi, causing the crude oil to disperse and come to the surface. The crude oil is then extracted from the spill through the use of skimmers and vacuum suction means and subsequently processed.

    摘要： 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.

    摘要： Bille (16) dont une surface extérieure est au moins partiellement recouverte d'un matériau qui lorsqu'on l'éclaire en présence d'air, peut accélérer l'oxydation de composés organiques flottant sur l'eau. La bille recouverte d'une couche de matériau peut flotter à la surface de l'eau et son diamètre équivaut à moins de 2 mm, de préférence il est de l'ordre de 10 à 30 microns. On peut utiliser ces billes recouvertes d'une couche de matériau pour accélérer sous l'effet de la lumière, l'oxydation d'une pellicule huileuse flottant sur l'eau (18) (provenant par exemple d'une fuite de pétrole), en dispersant ces dernières sur la pellicule et en les laissant s'oxyder au contact de la lumière solaire (24) et de l'oxygène ambiant.
