  • Patent number: 10046970
    Abstract: A two-step sc-SWCNT enrichment process involves a first step based on selective dispersion and extraction of semi-conducting SWCNT using conjugated polymer followed by a second step based on an adsorptive process in which the product of the first step is exposed to an inorganic absorptive medium to selectively bind predominantly metallic SWCNTs such that what remains dispersed in solution is further enriched in semiconducting SWCNTs. The process is easily scalable for large-diameter semi-conducting single-walled carbon nanotube (sc-SWCNT) enrichment with average diameters in a range, for example, of about 0.6 to 2.2 nm. The first step produces an enriched sc-SWCNT dispersion with a moderated sc-purity (98%) at a high yield, or a high purity (99% and up) at a low yield. The second step can not only enhance the purity of the polymer enriched sc-SWCNTs with a moderate purity, but also further promote the highly purified sample to an ultra-pure level.

  • Patent number: 9938161
    Abstract: A monitored release solid feed system having a solid chemical feed tank, a storage tank located below the solid chemical feed tank, and an automated valve. The solid chemical feed tank is loaded with a blend of inhibitors and an indicator-chemical in a solid form. A detector measures the amount of indicator in the recirculating water and periodically compares it to a setpoint. If the value is below the setpoint, the automated valve opens allowing water to pass through the storage tank and the solid chemical feed tank thus carrying inhibitors and a proportional amount of indicator-chemical into the recirculating system.

  • Patent number: 9815001
    Abstract: Processes are provided which utilize fiber conduit reactors/contactors to effect extraction from a fluid stream, particularly a fermentation broth, a waste stream of a fermentation process, a fluid comprising a dye, or a fluid comprising a pharmaceutical compound. In particular, methods are provided which include introducing a first stream comprising an extractant and a second stream which is substantially immiscible with the first stream into a conduit reactor proximate a plurality of fibers. The streams are introduced into the conduit reactor such that they are in contact with each other and the extractant of the first stream interacts with the second stream to extract a fermentation product, a fermentation byproduct, a dye or a pharmaceutical compound from the second stream into the first stream. The method further includes receiving the first and second streams in collection vessel/s and withdrawing separately the first and second streams from collection vessel/s.

  • Patent number: 9809681
    Abstract: A method for washing a polyarylene sulfide with a washing solution that contains a carefully controlled solvent content is provided. More particularly, the washing solution typically contains water (e.g., deionized water) in an amount of from about 30 wt. % to about 70 wt. % and an aprotic organic solvent in an amount of from about 30 wt. % to about 70 wt. %. Within such carefully controlled ranges, the present inventors have discovered that the polyarylene sulfide can retain a relatively high oligomer content, which in turn, helps minimize the melt viscosity.

  • Patent number: 9797109
    Abstract: A method for retracting oil on a water surface, and a method for reducing the quantity of oil on an oil control boom are described. Spreading of oil can be reversed by reducing the surface tension of the seawater, for example by using a low concentration of a water-soluble surfactant, such as a non-ionic surfactant. A controlled amount of the surfactant may be continuously discharged at the inner-wall of a spill control boom surrounding the oil spill. The spilled oil is caused to retract away from the boom toward the center of the area encircled thereby, such that the oil layer becomes sufficiently thick to be more effectively removed mechanically. The surfactant also reduces the amount of oil on the spill control boom, whereby the boom can easily be removed from a remediated oil spill and reused at a later date without further cleaning.

  • Patent number: 9610547
    Abstract: Composite porous hydrophobic membranes are prepared by forming a perfluorohydrocarbon layer on the surface of a preformed porous polymeric substrate. The substrate can be formed from poly (aryl ether ketone) and a perfluorohydrocarbon layer can be chemically grafted to the surface of the substrate. The membranes can be utilized for a broad range of fluid separations, such as microfiltration, nanofiltration, ultrafiltration as membrane contactors for membrane distillation and for degassing and dewatering of fluids. The membranes can further contain a dense ultra-thin perfluorohydrocarbon layer superimposed on the porous poly (aryl ether ketone) substrate and can be utilized as membrane contactors or as gas separation. membranes for natural gas treatment and gas dehydration.

    Abstract: A demulsification process for extracting surface active biochemical products from crude oil and its fractions when they are used as feedstock during biochemical productions utilizes subcritical/supercritical CO2 as a proton pump. The process also includes a pH tuning step, thereby inducing demulsification and precipitation of biochemical products into the aqueous phase, but avoiding asphaltene precipitation by apriori addition of resinous solvents derived from crude oil or bioresources. The biochemical products are then extracted from the aqueous phase via temperature change or some other technique.
