  • Patent number: 9938682
    Abstract: A system, device, and method quantitatively measure average concentrations of target constituents (e.g., volatile organic compounds (VOCs)) in an ambient fluid (e.g., groundwater, surface water, air, etc.) over an extended period of time. The system uses a passive device having an outer equilibration chamber and an inner kinetic sampler. The device is placed in an ambient fluid for a specified period of time, wherein the target constituent(s) rapidly diffuse through a high-permeability membrane into the fluid-filled equilibration chamber. From there, the target constituents are taken up by an uptake rate the kinetic sampler that is configured to be less than an equilibration rate of the equilibration chamber.

  • Patent number: 9868913
    Abstract: There is disclosed a system and method for processing diesel fuel from petroleum-based waste oil on a small scale compared to conventional methods for re-refining waste oil to a valuable product. In an embodiment, the method comprises dehydrating waste oil to remove water from the waste oil, and operating a vertical cylindrical reactor to induce pyrolysis of the dehydrated waste oil and convert it into a hydrocarbon vapor phase. The hydrocarbon vapor derived from pyrolysis is condensed and distilled using a distillation tower to produce diesel fuel, heavy liquid hydrocarbon, light liquid hydrocarbon and light hydrocarbon vapor. A filtering step cleans the processed diesel fuel to obtain a clean diesel fuel product.

    Abstract: A system for collecting matter provides a low energy, low cost and nearly zero pollutant process for extracting suspended matter in a medium. The system collects the matter on a material which is deployed into the medium, and the matter is extracted off the material. If an oil spill occurs in a body of water, then the material can rapidly remove the oil from the water in high concentrations. If oil or bitumen is mixed with water due to tar sands processing, then the material can extract the oil or the water depending on a balance of oleophilic or hydrophilic properties of the material. The extracted matter and the medium can proceed to further processing such as water purification and/or petroleum refining. This invention collects matter in an economically and environmentally viable manner.

  • Publication number: 20120238021
    Abstract: Methods for synthesizing macroscale 3D heteroatom-doped carbon nanotube materials (such as boron doped carbon nanotube materials) and compositions thereof. Macroscopic quantities of three-dimensionally networked heteroatom-doped carbon nanotube materials are directly grown using an aerosol-assisted chemical vapor deposition method. The porous heteroatom-doped carbon nanotube material is created by doping of heteroatoms (such as boron) in the nanotube lattice during growth, which influences the creation of elbow joints and branching of nanotubes leading to the three dimensional super-structure. The super-hydrophobic heteroatom-doped carbon nanotube sponge is strongly oleophilic and an soak up large quantities of organic solvents and oil. The trapped oil can be burnt off and the heteroatom-doped carbon nanotube material can be used repeatedly as an oil removal scaffold.

  • Patent number: 8207298
    Abstract: The invention relates to methods for separating or purifying biopolymer conjugated molecules from unconjugated molecules. In particular, methods are described for purifying a PEGylated protein or oligonucleotide from an unPEGylated protein or oligonucleotide, respectively. The methods are quick and efficient separation methods because they do not require gradient chromatography, fractionation of an eluent or analysis of the eluted fractions. Further, the methods increase yield and purity of the biopolymer conjugated molecule.

  • Patent number: 8187469
    Abstract: The invention relates to a method of separating fluids from mixtures using a zeolite known as ITQ-32 consisting of a two-dimensional pore system comprising channels with openings formed by 8 tetrahedra which are interconnected by channels with openings formed by 12 tetrahedra. The inventive method comprises at least the following steps: a) the zeolite ITQ-32 material is brought into contact with the mixture of fluids, b) one or more of the components are adsorbed in the zeolite ITQ-32 material, c) the non-adsorbed components are extracted, and d) one or more of the components adsorbed in the zeolite ITQ-32 material are recovered.
