Publication number: 20230030534Abstract: A printed circuit board (PCB) includes first and second signal voids and a guard trace formed on a surface of the PCB. The first and second signal voids are for connecting to signal contacts of a high-speed data communication interface. The guard trace is located between the first signal void and the second signal void. The PCB further includes first, second, and third ground vias that couple the guard trace to a ground plane of the PCB. The first ground via is located at a first end of the guard trace. The second ground via is located at a second end of the guard trace. The third ground via is located between the first via and the second via.Type: ApplicationFiled: October 26, 2021Publication date: February 2, 2023Inventors: Vijender Kumar, Malikarjun Vasa, Bhyrav Mutnury

Patent number: 10766836Abstract: Systems and methods for separating one or more olefins are provided. In one or more embodiments, the method for separating one or more olefins can include separating at least a portion of one or more C3 and heavier hydrocarbons from a hydrocarbon containing C1 to C20 hydrocarbons to provide a first mixture that can include methane, ethane, ethylene, and/or acetylene. At least a portion of the first mixture can be hydrogenated to convert at least a portion of the acetylene to ethane and ethylene. At least a portion of the methane can be separated from the hydrogenated mixture to provide a second mixture that can include ethane and ethylene. At least a portion of the ethylene can be separated from the second mixture to provide a first product that can include at least 95 mol % ethylene and a second product that can include at least 95 mol % ethane.Type: GrantFiled: March 13, 2014Date of Patent: September 8, 2020Assignee: KELLOGG BROWN & ROOT LLCInventors: Vijender Kumar Verma, Curtis Eng

Patent number: 8256243Abstract: Methods and apparatus for the integration of a fractionation process and an olefin refrigeration system, wherein the fractionation process olefin effluent is supplied to the refrigeration system, can eliminate a fractionation process condenser and reflux drum typically present. A plurality of bottoms streams can be collected from the fractionation process. The olefin refrigerant can be supplied to alternate olefin refrigerant consumers, as desired. A column in the fractionation process can be refluxed with an olefin stream from refrigeration system, and olefin product can be collected or exported via line.Type: GrantFiled: December 16, 2006Date of Patent: September 4, 2012Assignee: Kellogg Brown & Root LLCInventor: Vijender Kumar Verma

Patent number: 7628197Abstract: Apparatus and processes for quenching a pyrolysis furnace effluent are provided. In one embodiment, a hydrocarbon stream comprising gas and oil vapor can be quenched with a first quench water stream to form a mixed vapor-liquid stream. The mixed vapor-liquid stream can be fed to a water quench tower to separate the vapor and liquid. The separated vapor can be further quenched with a second quench water stream in the quench tower to form an overhead vapor product comprising light hydrocarbons. Water and liquid hydrocarbons can be collected from the quench tower in an oil-water separator. The liquid hydrocarbons can be recovered from the oil-water separator. Water can be recovered from the oil-water separator. A portion of the recovered water can be cooled. The cooled water can be recycled to the first and second quench water streams.Type: GrantFiled: December 16, 2006Date of Patent: December 8, 2009Assignee: Kellogg Brown & Root LLCInventor: Vijender Kumar Verma

Patent number: 5877380Abstract: The viscosity of quench oil circulated in a pyrolysis fractionation unit is controlled by contacting pyrolysis furnace effluent with a slip stream of 0.1-0.5 kg/kg of the quench oil, separating the resulting vapor-liquid mixture to remove tarry liquid, and feeding the remaining vapor to the fractionator. Removing the tarry liquid from the fractionator feed in this manner allows operation of the fractionator with less reflux, a higher bottoms temperature, and more heat recovery at a higher temperature.Type: GrantFiled: October 27, 1997Date of Patent: March 2, 1999Assignee: The M.
