Publication number: 20190359899Abstract: Systems and methods are provided for hydroconversion of a heavy oil feed under slurry hydroprocessing conditions and/or solvent assisted hydroprocessing conditions. The systems and methods for slurry hydroconversion can include the use of a configuration that can allow for improved separation of catalyst particles from the slurry hydroprocessing effluent. In addition to allowing for improved catalyst recycle, an amount of fines in the slurry hydroconversion effluent can be reduced or minimized. This can facilitate further processing or handling of any “pitch” generated during the slurry hydroconversion. The systems and methods for solvent assisted hydroprocessing can include processing of a heavy oil feed in conjunction with a high solvency dispersive power crude.Type: ApplicationFiled: August 6, 2019Publication date: November 28, 2019Inventors: Benjamin S. UMANSKY, Himanshu GUPTA, John D. NELSON, Cindy J. HUGHART, Jane C. CHENG, Steven W. LEVINE, Stephen H. BROWN, Todd P. MARUT, David C. DANKWORTH, Stuart L. SOLED, Thomas F. DEGNAN, JR., Robert J.

Patent number: 4668129Abstract: A retaining wall system which uses rigid tieback elements having portions, column portions and web portions and wall panels disposed between the tieback elements. The tieback elements are designed to produce arching in the soil to reduce bearing stresses on the soil below base portions of the tieback elements by providing web portions sufficiently large to produce a complete ditch condition in the soil upon movement of the rigid tieback elements. This provides an economical retaining wall system in which multiple tiered walls can be spaced by an amount sufficient to produce a complete ditch condition. The wall can be implemented as a vertical wall or as a battered wall.Type: GrantFiled: September 6, 1985Date of Patent: May 26, 1987Assignee: Stresswall International IncorporatedInventors: John W. Babcock, Ronald K. Wormus, John D. Nelson
