Patent number: 10124298Abstract: A filter medium for oil-water separation, the filter medium being a composite, nanofibrous mat formed from electrospinning a single solution of one natural polymer and one synthetic polystyrene polymer together, where fibers of the natural polymer are reinforced by fibers of the synthetic polystyrene polymer. The nanofibrous mat may initially be hydrophobic and oleophilic, making it a suitable filter medium for separating oil from oil-water mixtures. The mat may be treated with one or more surfactants to change the surface wettability of the mat to hydrophilic and oleophobic for separating water from oil-water mixtures or to hydrophobic and oleophobic for separating oil and water droplets from wet gas.Type: GrantFiled: July 6, 2016Date of Patent: November 13, 2018Assignee: The University of TulsaInventors: Lida Baghernejad, Erin Iski, Ram S. Mohan, Ovadia Shoham, Seyi Odueyungbo

Patent number: 8470252Abstract: A process to upgrade heavy oil and convert the heavy oil into lower boiling hydrocarbon products is provided. The process employs a catalyst slurry comprising catalyst particles with an average particle size ranging from 1 to 20 microns. In the upgrade process, spent slurry catalyst in heavy oil is generated as an effluent stream, which is subsequently recovered/separated from the heavy oil via membrane filtration. Residual hydrocarbons, i.e., heavy oil and solvent employed in the filtration for the heavy oil extraction are removed from the catalyst particles in a drying zone which employs at least two drying apparatuses to volatize residual hydrocarbons in the catalyst. Valuable metals can be recovered from catalyst particles for subsequent re-use in a catalyst synthesis unit, generating a fresh slurry catalyst.Type: GrantFiled: April 13, 2012Date of Patent: June 25, 2013Assignee: Chevron U.S.A. Inc.Inventor: Seyi A. Odueyungbo

The process employs a catalyst slurry comprising catalyst particles with an average particle size ranging from 1 to 20 microns. In the upgrade process, spent slurry catalyst in heavy oil is generated as an effluent stream, which is subsequently recovered/separated from the heavy oil via membrane filtration. In one embodiment, residual hydrocarbons, i.e., heavy oil and solvent employed in the filtration for the heavy oil extraction are removed from the catalyst particles with the use of a cleaning solution comprising a sufficient amount of at least a surfactant for removing at least 90% of the hydrocarbons from the catalyst particles. In one embodiment, ultrasonic cleaning is also used for the removal of hydrocarbons. In another embodiment, a plasma source is employed for the volatilization of the hydrocarbons.Type: GrantFiled: December 30, 2008Date of Patent: February 14, 2012Assignee: Chevron U.S.A.

Publication number: 20100163499Abstract: A process to upgrade heavy oil and convert the heavy oil into lower boiling hydrocarbon products is provided. The process employs a catalyst slurry comprising catalyst particles with an average particle size ranging from 1 to 20 microns. In the upgrade process, spent slurry catalyst in heavy oil is generated as an effluent stream, which is subsequently recovered/separated from the heavy oil via membrane filtration. In one embodiment, a sufficient amount of solvent is first added to the stream comprising the spent slurry catalyst in heavy oil to break up the colloidal suspension of the heavy oil, reduce the effective viscosity and density of the continuous liquid phase and hence enhance the separation into two phases with the bottom phase comprising catalyst particles in solvent and with a reduced heavy oil concentration. Valuable metals can be recovered from catalyst particles for subsequent re-use in a catalyst synthesis unit, generating a fresh slurry catalyst.Type: ApplicationFiled: December 30, 2008Publication date: July 1, 2010Inventor: Seyi A.

Patent number: 6833078Abstract: Methods and apparatus for separating liquid products and catalyst fines from a slurry used in a Fischer-Tropsch reactor. A settling system continuously or intermittently removes catalyst fines from the slurry and is coupled with catalyst-liquid separation system that separates liquid products from the slurry. The preferred separation system produces a sub-particle rich stream and a catalyst-lean stream that are removed from the system. The systems of the present invention act to reduce the concentration of catalyst fines in the reactor, thereby increasing the effectiveness of a catalyst-liquid separation system.Type: GrantFiled: September 13, 2002Date of Patent: December 21, 2004Assignee: ConocoPhillips CompanyInventors: Rafael L.
