Abstract: System in fluid communication with an oil-contaminated water supply, such as a water leg portion of an offshore drilling or production platform sump tank, for conveying the separated water into contact with an organophilic clay in a vessel maintained at an operating pressure of at least 10 psig, such that the hydrocarbons and other organic material will be adsorbed onto the organophilic clay and will be conveyed back to the ocean water without contamination.
Abstract: Intercalated layered materials prepared by reacting the layered material with a coupling agent and co-intercalating an onium ion and an oligomer or polymer between the planar layers of a swellable layered material, such as a phyllosilicate, preferably a smectite clay. The spacing of adjacent layers of the layered materials is expanded at least about 3 Å, preferably at least about 5 Å, usually preferably to a d-spacing of about 15-20 Å, e.g., 18 Å with the onium ion spacing/compatibilizing agent. The intercalation of the oligomer or polymer then increases the spacing of adjacent layers an additional at least 3 Å, e.g., to at least about 20 Å, preferably about 25 Å to about 30 Å, generally about 28 Å, and provides a nanocomposite having increased tensile strength, flexibility, and ductility (less brittle).

Abstract: Apparatus in fluid communication with a water leg portion of a hydrocarbon-contaminated water, e.g., a water leg portion of an offshore drilling or production platform sump tank for conveying water, separated from oil, into contact with organophilic media canisters such that the hydrocarbons and other organic materials commingled with the sump tank water will be adsorbed onto the organophilic media and detected by the embedded probe in selected canisters. The canisters are provided in a plurality of stacks and are in fluid communication with a header disposed at the bottom of the vessel housing the various stacks of canisters. Solids that do not pass through the canisters are accumulated at the bottom of the vessel and easily drained through a drain port. The water will pass through the media and will be conveyed back to the ocean water without contamination.

Abstract: Intercalated layered materials prepared by co-intercalation of a multi-charged onium ion spacing/coupling agent and a matrix polymer between the planar layers of a swellable layered material, such as a phyllosilicate, preferably a smectite clay. The spacing of adjacent layers of the layered materials is expanded at least about 3 Å, preferably at least about 5 Å, usually to about 15-20 Å, e.g., 18 Å with the di-charged onium ion spacing/coupling agent. The intercalation of the matrix polymer then increases the spacing between adjacent layers to at least about 15 Å, preferably to about 20 Å to about 30 Å.

Abstract: Intercalates formed by contacting a layered material, e.g., a phyllosilicate, with an intercalant monomer ether and/or ester to sorb or intercalate the intercalant monomer between adjacent platelets of the layered material. Sufficient intercalant monomer is sorbed between adjacent platelets to expand the adjacent platelets to a spacing of at least about 5 Å (as measured after water removal to a maximum of 5% by weight water), up to about 100 Å and preferably in the range of about 10-45 Å, so that the intercalate easily can be exfoliated into individual platelets. The intercalated complex can be combined with an organic liquid into a viscous carrier material, for delivery of the carrier material, or for delivery of an active compound; or the intercalated complex can be combined with a matrix polymer to form a strong, filled polymer matrix. Alternatively, the intercalated complex can be exfoliated prior to combination with the organic liquid or the matrix polymer.

Abstract: Intercalates formed by contacting a layered material, e.g., a phyllosilicate, with an intercalant onium ion spacing agent and an anhydride-curable epoxy resin. The intercalant onium ion spacing agent converts the interlayer region of the layered materials from hydrophilic to hydrophobic, therefore, the anhydride-curable epoxy resin can be easily intercalated into the interlayer spacing. The co-presence of the co-intercalant anhydride-curable epoxy resin in the interlayer space provides surprising increase in glass transition temperature for anhydride-curable epoxy resin matrix polymer/co-intercalant compounded nanocomposites. The nanocomposites (e.g., epoxy-clay) prepared from the intercalants demonstrate enhanced mechanical, thermal and chemical resistance compared with pristine polymer matrices.
Abstract: Intercalates formed by contacting a layered material, e.g., a phyllosilicate, with an intercalant surface modifier selected from the group consisting of a compound having an alkyl radical containing at least 6 carbon atoms, a compound containing an aromatic ring, and mixtures thereof, said surface modifier including a matrix material-reactive functional group, to sorb or intercalate the intercalant surface modifier between adjacent platelets of the layered material. Sufficient intercalant surface modifier is sorbed between adjacent platelets to expand the adjacent platelets to at least about 10 Å, up to about 100 Å. The intercalated complex can be combined with an organic liquid into a viscous carrier material, for delivery of the carrier material, or for delivery of an active compound; or the intercalated complex can be combined with a matrix polymer to form a strong, filled polymer matrix.

Abstract: Apparatus in fluid communication with a water leg portion of a hydrocarbon-contaminated water, e.g., a water leg portion of an offshore drilling or production platform sump tank for conveying water, separated from oil, into contact with organophilic clay cannisters such that the hydrocarbons and other organic materials commingled with the sump tank water will be adsorbed onto the organophilic clay and detected by the embedded probe in selected cannisters. The water will pass through the clay and will be conveyed back to the ocean water without contamination. At some point in time, the organophilic clay will become “spent” and at a certain “spent level”, the saturated condition of the organoclay will be electronically detected by the embedded probe and alarm/control panel. The alarm indicates that the “spent” organophilic clay should be replaced with fresh clay or the spent clay regenerated.

Abstract: A method of determining a quantity of amorphous SiC2-containing impurities in a montmorillonite clay sample comprising the steps of:
(a) analyzing the clay sample to determine the weight percent of SiO2 contained in the clay sample;
(b) analyzing the clay sample for non-montmorillonite SiO2-containing crystalline components;
(c) calculating the weight percent of SiO2 from step (a) that is derived from the montmorillonite and amorphous SiQ2-containing impurities by lowering the weight percent of SiO2 in step (a) based on the non-montmorillonite SiO2-containing crystalline impurities found in step (b); and
(d) determining the amorphous SiO2-containing impurity portion of the SiO2 calculated in step (c) by further lowering the amount of SiO2 from step (c) until the amount of montmorillonite-derived SiO2 is consistent with one or more properties of the clay sample, the amount of further lowering being proportional to an amount of amorphous SiO2-containing impurities contained in the clay sample.
