  • Patent number: 10640379
    Abstract: A process for the production of monochloramine characterized in that it provides for drawing a portion of water intended for the user and exclusively using the portion for preparing the monochloramine solution. The portion intended for the reaction of formation of monochloramine is subjected to a treatment on osmotic membrane, obtaining osmotized water. Subsequently, there is the reaction of the water with reagents in a reactor. In the reaction step, inside the reactor, the osmotized water enters from a first orifice (C) via a solenoid valve with micrometric regulation (EV1). Inside the same reactor, the base chemical products enter via the respective orifices A and B. The base chemical products enter due to the action of metering pumps (e.g. peristaltic pumps). The system is managed by PLC.

  • Patent number: 9713788
    Abstract: A method is described for separating CO2 and/or H2S from a mixed gas stream by contacting the gas stream with a non-aqueous, liquid absorbent medium of a primary and/or secondary aliphatic amine, preferably in a non-aqueous, polar, aprotic solvent under conditions sufficient for sorption of at least some of the CO2. The solution containing the absorbed CO2 can then be treated to desorb the acid gas. The method is usually operated as a continuous cyclic sorption-desorption process, with the sorption being carried out in a sorption zone where a circulating stream of the liquid absorbent contacts the gas stream to form a CO2-rich sorbed solution, which is then cycled to a regeneration zone for desorption of the CO2 (advantageously at <100° C.). Upon CO2 release, the regenerated lean solution can be recycled to the sorption tower. CO2:(primary+secondary amine) adsorption molar ratios>0.5:1 (approaching 1:1) may be achieved.

    Abstract: Processes for recovering inorganic powder materials from polymer-based coating compositions used to deposit a polymer-based coating. The process includes combining a polymer precursor, first solvent, and inorganic powder material to form a suspension, and applying the suspension to a substrate to form a layer. At least a portion of the suspension that did not adhere to the substrate is then collected. Residual portions of the first solvent and polymer precursor are at least partially removed from this portion of the suspension to yield a crude inorganic powder material comprising a residual portion of the inorganic powder and optionally a partially-cured polymer precursor, the latter of which can be removed by treating the crude inorganic powder material with a second solvent.

  • Patent number: 9180411
    Abstract: The invention relates to the treatment of water, including for example treatment in connection with hydrocarbon production operations. Silica in water produces undesirable scaling in processing equipment, which causes excess energy usage and maintenance problems. Electrocoagulation (EC) at relatively high water temperature, followed by any of membrane distillation or forward osmosis (FO), may be combined with a subsequent process of ceramic ultra-filtration (UF filtration) employed to treat water. Water to be treated may be produced water that has been pumped from a subterranean reservoir. The treated water may be employed to generate steam. The treatment units (e.g., EC, forward osmosis, UF filtration, etc) can be configured into one system as an on-site installation or a mobile unit for on-site or off-site water treatment.

  • Patent number: 9085476
    Abstract: Liquid membrane systems are provided for use in pervaporation techniques that achieves high selectivity, ensure stability and prevent contamination of the fermentation broth. Tri-n-octylamine (TOA), tri-laurlyamine or tri-decylamine as a liquid membrane is immobilized in the pores of a hydrophobic hollow fiber substrate having a nanoporous hydrophobic coating on the broth side. The liquid membrane in the coated hollow fibers demonstrate high selectivity and reasonable mass fluxes of solvents in pervaporation. The mass fluxes were substantially increased with the same selectivity of solvents when an ultrathin liquid membrane was used. The addition of butanol into the feed solution increases membrane selectivity.

The desalination facility includes a nanofiltration membrane section producing a first tailings stream and a reverse osmosis membrane section producing a second tailings stream and a desalinated water outlet stream from an inlet feed stream. The extraction facility produces at least one mineral compound, an extraction tailings stream, and a second desalinated water outlet stream. At least one of the first tailings stream and the second tailings stream is fed into the extraction facility. In certain exemplary embodiments, a natural gas combined cycle power unit supplies power to at least one of the desalination facility and the extraction facility. In certain exemplary embodiments, the extraction tailings stream is recycled into the desalination facility and there are no extraction tailings streams or desalination tailings streams discharged into the environment.

  • Publication number: 20150129493
    Abstract: A method for removal of at least a portion of carbon dioxide from an aqueous fluid such as a blood fluid includes placing a first surface of at least one membrane through which carbon dioxide and at least one acid gas other than carbon dioxide can pass in fluid in contact with the fluid. The membrane limits or prevent passage of the fluid therethrough. A carrier or sweep gas including the acid gas other than carbon dioxide is passed over a second surface (which is typically opposite the first surface) of the membrane so that the acid gas other than carbon dioxide can pass through the membrane into the fluid, and carbon dioxide from the fluid can pass from the liquid, through the membrane, and into the sweep gas.

  • Patent number: 9028697
    Abstract: The moisture absorption capacity of biofuels can be more or less 10 times that of fossil diesel oil, causing biofuels to form acids that induce metal corrosion and form deposits in the fuel tank and pipe lines. Methods for removing moisture from stored biofuels and plant oils are described wherein glycerol is used as a solvent to extract the moisture from the bioliquid or oil, comprising the steps of placing the biofuel or oil in fluid contact with glycerol, incubating for a time, and then removing the glycerol. A cellulous ester dialysis or other semi-permeable membrane may be used to prevent the glycerol from contaminating the biofuel while allowing moisture to pass. Crude glycerol produced as a byproduct of biodiesel production may be used in the method of the disclosed invention with good result. Preferred embodiments of apparatus that employ the method of the subject invention are described.
