International Classification:

C02F 124

US Classification:

210703, 210788, 210789, 2102212, 2105121, 210197, 210708, 210799, 669691, 669266, 669202

Abstract:

An improved production water treatment system and method are disclosed. The treatment apparatus includes a vertically oriented vessel with tangentially disposed injection nozzles including one or more injection nozzles for the introduction of production water and one or more injection nozzles for the introduction of recycled water from the vessel and a sparge gas. The tangential orientation of the injection nozzles creates a cyclonic flow within the vessel for improved sparge gas bubble/hydrocarbon contact. A hydrocarbon-rich layer migrates to the top surface of the liquid in the vessel where it is removed about a center axis of the vessel. The resulting hydrocarbon-lean production water has a sufficiently low hydrocarbon content that it is eligible for more intensive processing, such as with organophillic clay cartridges.

International Classification:

US Classification:

210/085000

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. At some point in time, the organophilic media will become “spent” and at a certain “spent level”, the saturated condition of the organomedia will be electronically detected by the embedded probe and alarm/control panel. The alarm indicates that the “spent” organophilic media should be replaced with fresh media or the spent media regenerated.

Abstract:

Cosmetic and personal care compositions can be manufactured using the multifunctional-additive compositions of the present invention. Such an additive preferably contains one or more particulate-based thickeners, such as a smectite clay, colloidal silica, laponite, and/or alumina, and most preferably one or more smectite clays. According to one important embodiment of the present invention, the thickener particles are co-dispersed with particles of one or more particulate UVR-filters such as titanium dioxide, zinc oxide, or SUNSPHERE (available from International Specialty Chemicals, ISP), and most preferably with the natural particulate sunscreens such as the metal oxides. Another important component of the multifunctional-additive compositions is a dispersant or surface-modifier for the foregoing particulate materials, selected from the family of polyphenolic, natural polymers such as lignosulfonates, lignins, humates, tannates, and derivatives thereof. In addition, these compositions optionally include one or more of the following components: electrolytes, defoamers, humectants, emollients for cosmetics, preservatives, whiteners, and the like.

Abstract:

By applying a polymerization catalyst or polymerization initiator directly to a liquid-absorbent or liquid-adsorbent (hereinafter collectively referred to as “liquid-sorbent”) substrate, preferably a porous geotextile in sheet material form, to form a polymerization-initiating substrate or sheet material, a slurry of a monomer and a water-absorbent clay that is subsequently embedded in the porous substrate will have its monomer content sufficiently contacted by the polymerization catalyst or polymerization initiator for complete polymerization of the embedded monomer to form embedded polymer solids and clay, without the monomer partially polymerizing before contacting the substrate. It has been found that polymerization of the monomer while in contact with the substrate achieves best results in retention of embedded and interlocked polymer and clay solids. Preferably only the polymerization catalyst or polymerization initiator, and optionally a cross-linker for the monomer, and/or a polymer neutralizing agent, together with any carrier, such as water or an organic solvent, are applied to the liquid-sorbent substrate prior to embedding the monomer into the substrate. In another embodiment, the cross-linker and/or the polymer neutralizing agent are embedded into the substrate together with the polymerization catalyst and/or polymerization initiator.

524/445000

Abstract:

Concentrated suspensions of smectite clays are obtained as either relatively “thin” or highly shear-thinning slurries that are easy to pump, by adding one or more of certain cationic polymers whose weight average molecular weight, Mw, is 50,000 or higher. It was found during the course of the invention that a cationic polymer with an Mw of 10,000 did not work, while the same polymer with a bimodal Mw of 50,000 and 30,000 worked satisfactorily. To achieve the full advantage of the present invention, the cationic polymer preferably has 1 to 10 milliequivalents of cationic charge per gram of the polymer, and more preferably 5 to 10 milliequivalents of cationic charge per gram of the polymer, and most preferably 6 to 8 milliequivalents of cationic charge per gram of the polymer.
