Title: Improved method for collecting matter with a matter collection unit
Inventor: MARTIN JONATHAN E
IPC: C02F1/28
Filed: 2011-10-10
Abstract: A method for collecting matter using a matter collection Unit, as described below, provides a low energy, low cost and nearly zero pollutant process for extracting suspended and/or dissolved matter in a medium. The method collects the matter on a material when the medium is permitted to flow past the material which is disposed within a chamber, and the medium, with less suspended matter, can flow back to a medium body to permit, e.g., further growth and/or higher collection efficiency. The process can operate continuously alongside, e.g. a growth system, to harvest suspended matter until the matter is ready for extraction. Post extraction collected matter, e.g., can be converted into valuable commercial products or the process can be used to remediate a medium, such that the valuable product is a substantially cleaner medium.

Abstract: The invention provides a method for preparing a carboxylic acid, which method comprises the steps of - providing magnesium carboxylate, wherein the carboxylic acid corresponding with the carboxylate has a solubility in water at 20 °C of 80 g/100 g water or less; - acidifying the magnesium carboxylate with HCl, thereby obtaining a solution comprising carboxylic acid and magnesium chloride (Mg Cl2); - optionally a concentration step, wherein the solution comprising carboxylic acid and MgCl2 is concentrated; - precipitating the carboxylic acid from the solution comprising the carboxylic acid and MgCl2, thereby obtaining a carboxylic acid precipitate and a MgCl2 solution. The inventors found that the addition of HCl to a magnesium salt of the carboxylic acid and subsequent precipitation of the carboxylic acid from the solution leads to a very efficient separation of the carboxylic acid from a magnesium carboxylate solution.

Abstract: The valve is integrated into a fluid distribution network and makes it possible, in a selective manner, to interrupt or authorize the flow of a fluid in an axial direction of a pipe. This valve comprises an external body (20), inside which a shut-off member (22) is disposed, a service seal (220) which, in a shut-off position of the valve, provides sealing between the shut-off member and the body (20) of the valve, and a maintenance sealing mechanism (M) which is disposed upstream of the service seal (220) and which provides sealing during maintenance operations on the service seal (220). The mechanism (M) comprises a ring (206) which is able to move axially, with respect to the body (20) of the valve, between a retracted position, in which it does not prevent the passage of the fluid, and a forward position, where it bears in a sealing manner against the shut-off member (22).

Title: Process to obtain random copolymers derived from itaconic acid and/or its isomers and sodium alkenyl sulfonates and use of the product thereof
Inventor: HERNANDEZ ALTAMIRANO RAUL
IPC: C08F220/54
Filed: 2014-04-24
Abstract: The present invention relates to the process for obtaining random copolymers based on itaconic acid and/or isomers and sodium alkenyl sulfonates, by means of polymerization in aqueous solution via free radicals at an acidic pH in the range from 1.0 to 3.5 and with a redox system as initiator, and the use thereof as calcium carbonate and calcium, strontium and barium sulfates mineral scale inhibitors and as dispersants of clays, iron oxides, calcium carbonate and strontium, barium and calcium sulfates. Random copolymers prevent and control damage to the formation by mineral salts scale that occurs in an oil reservoir, obstruction of water injection and crude oil production pipelines, as well as in production rigs due to mineral scale precipitation, all this as a consequence of high levels of salinity of the formation water and incompatible mixtures of injection water and formation water. Random copolymers are characterized for being tolerant to high concentrations of divalent ions, such as calcium, magnesium, strontium and barium, and by the fact that for its application to the reservoir and to injection or production pipelines, treated water, sea water and water that is characteristic of the reservoir (formation water) can be used as means of transportation. On the other hand, the copolymers can also be used to inhibit and disperse mineral scale occurring in cooling systems and boilers used in the oil and chemistry industry. Furthermore, the random copolymers of the present invention are characterized for meeting internationally established environmental standards and are classified as particularly non-toxic and therefore they can be used in pipelines and equipment from oil and chemical industry that uses fresh water and sea water that are characteristic of offshore and inland facilities.
