Patent number: 8109047Abstract: A constructed permeability control infrastructure can include a permeability control impoundment defining a substantially encapsulated volume. A comminuted water-containing hydrocarbonaceous material can form a permeable body within the encapsulated volume. The impoundment includes a water vapor outlet for removing water vapor from the encapsulated volume. A heating device is also embedded within the permeable body to provide convective heating thereof. The permeable body can be heated sufficient to initially remove water therefrom as a water vapor. The water vapor can be removed from the infrastructure via the outlet which can be controlled or shut off when the permeable body is sufficiently dewatered. The dewatered permeable body can then be heated sufficient to remove hydrocarbons therefrom. During heating the hydrocarbonaceous material is substantially stationary as the constructed infrastructure is a fixed structure.Type: GrantFiled: January 4, 2011Date of Patent: February 7, 2012Assignee: Red Leaf Resources, Inc.Inventors: Todd Dana, James W.

Patent number: 8097149Abstract: Oil soluble catalysts are used in a process to hydrodesulfurize petroleum feedstock having a high concentration of sulfur-containing compounds and convert the feedstock to a higher value product. The catalyst complex includes at least one attractor species and at least one catalytic metal that are bonded to a plurality of organic ligands that make the catalyst complex oil-soluble. The attractor species selectively attracts the catalyst to sulfur sites in sulfur-containing compounds in the feedstock where the catalytic metal can catalyze the removal of sulfur. Because the attractor species selectively attracts the catalysts to sulfur sites, non-productive, hydrogen consuming side reactions are reduced and greater rates of hydrodesulfurization are achieved while consuming less hydrogen per unit sulfur removed.Type: GrantFiled: June 17, 2008Date of Patent: January 17, 2012Assignee: Headwaters Technology Innovation, LLCInventors: Zhihua Wu, Zhenhua Zhou, Bing Zhou

Patent number: 8083156Abstract: A dispersion apparatus for dispersing a treating agent into a fluid treatment system that includes a flow duct in which a fluid stream flowing through the duct is mixed with the treating agent. The apparatus is based on a multi-pipe lance positioned in the stream flow, where each pipe supplies a minimum of feed discharge nozzles (typically one to four), and the individual pipes branch off from the same location. Use of the multi-pipe lance, in combination with a suitable baffle, results in better overall dispersion/distribution of the injected medium by surface area. By improving the surface area distribution, better utilization of the injected sorbent can be achieved. The baffle acts to generate a low pressure zone on its downstream side and creates a high-intensity turbulence plume in the fluid. The orifices of the pipe are located to inject the treating agent into the turbulence plume to better distribute and intermix the injected treating agent into the surrounding fluid.Type: GrantFiled: May 28, 2009Date of Patent: December 27, 2011Assignee: URS CorporationInventors: Scott D. Miller, Mark A. Denlinger
