Method for Enhancing Selectivity and Recovery in the Fractional Flotation of Flotation Column Particles USPN 7,992,718

Although research is currently inactive on the patented technology "Method for Enhancing Selectivity and Recovery in the Fractional Flotation of Flotation Column Particles," the technology is available for licensing from the U.S. Department of Energy’s National Energy Technology Laboratory (NETL).

Disclosed in this patent is a method of particle separation from a feed stream comprised of particles of varying hydrophobicity by injecting the feed stream directly into the froth zone of a vertical flotation column in the presence of a counter-current reflux stream. The current invention allows the height of the feed stream injection and the reflux ratio to be varied to optimize the concentrate or tailing stream recoveries desired based on existing operating conditions or other considerations. This novel method provides a high degree of particle collection with reduced carryover of lower hydrophobic or hydrophilic particles to the froth overflow, reduces or eliminates reliance on a clean wash-water supply, allows capture of coarse particles beyond the upper limiting size for liquid injection columns, allows capture of fine particles while mitigating the tendency of the low inertia particles to follow bubble streamlines and avoid capture, and provides other benefits over previously used methods of capture.

A Unique Split Laser System for Environmental Monitoring USPN 7,421,166; USPN 8,786,840; USPN 8,934,511; USPN 9,297,696; USPN 9,548,585

Researchers at the U.S. Department of Energy’s National Energy Technology Laboratory (NETL) have developed a novel split laser system for in situ environmental monitoring via Laser Induced Breakdown Spectroscopy (LIBS) or Raman analysis.  The design features fiber-coupled, optically-pumped, passively Q-switched lasers that are small, portable, low cost and robust enough for even downhole applications.  The technology can be used in a wide array of applications, including, but not limited to, carbon dioxide (CO2) monitoring for CO2 sequestration, oil and gas monitoring, and water analysis (groundwater and municipal systems).  The technology is available for licensing and/or further collaborative research with NETL.

Proof of concept experimentation has been completed. NETL researchers are continuing to design miniaturized lasers and optical delivery systems to allow further size and cost reductions. The researchers have identified the need to complete and demonstrate both single point and multipoint measurement prototypes.  The results would further validate the technology and expedite its deployment to the private sector.

Optimum Catalyst Size Selection for Slurry Bubble Column Reactors USPN 7,619,011

The Department of Energy’s National Energy Technology Laboratory (NETL) is seeking licensing partners interested in implementing United States Patent Number 7,619,011 titled "Design of Slurry Bubble Column Reactors: Novel Technique for Optimum Catalyst Size Selection."

Disclosed in this patent is a method to determine the optimum catalyst particle size for application in a fluidized bed reactor, such as a slurry bubble column reactor (SBCR), to convert synthesis gas into liquid fuels. The reactor can be gas-solid, liquid-solid, or gas-liquid-solid. The method considers the complete granular temperature balance based on the kinetic theory of granular flow, as well as the effect of a volumetric mass transfer coefficient between the liquid and the gas. After the method computes the granular temperature of the catalyst particles, the volumetric mass transfer coefficient between the gas and liquid phases is calculated using that temperature. The method then can determine the optimum catalyst particle size to maximize the production of fuels in fluidized bed reactors such as SBCRs.

Rapid Gas Hydrate Formation Process USPN 8,354,565

The Department of Energy’s National Energy Technology Laboratory (NETL) is seeking collaborative research and licensing partners interested in implementing United States Non-provisional Patent Application entitled "Rapid Gas Hydrate Formation Process." Disclosed in this application is a method and device for producing gas hydrates from a two-phase mixture of water and a hydrate forming gas such as methane (CH4) or carbon dioxide (CO2). The two-phase mixture is created in a mixing zone, which may be contained within the body of the spray nozzle. The two-phase mixture is subsequently sprayed into a reaction vessel, under pressure and temperature conditions suitable for gas hydrate formation. The reaction zone pressure is less than the mixing zone pressure so that expansion of the hydrate-forming gas in the mixture provides a degree of cooling and better mixing between the water and the hydrate-forming gas. The result of the process is the continuous formation of gas hydrates with a greatly reduced induction time for gas hydrate crystal formation. This invention may have utility in natural gas / CH4 storage and transport, COsequestration, cold energy storage, transportation fuels, and desalination.
