Patent number: 9593881Abstract: Provided is a natural gas processing facility for the liquefaction or regasification of natural gas. The facility includes a primary processing unit, e.g., refrigeration unit, for warming natural gas or chilling natural gas to at least a temperature of liquefaction. The facility also has superconducting electrical components integrated into the facility. The superconducting electrical components incorporate superconducting material so as to improve electrical efficiency of the facility by at least one percent over what would be experienced through the use of conventional electrical components. The superconducting electrical components may be one or more motors, one or more generators, one or more transformers, switch gears, one or more electrical transmission conductors, variable speed drives, or combinations thereof.Type: GrantFiled: January 6, 2011Date of Patent: March 14, 2017Assignee: ExxonMobil Upstream Research CompanyInventors: Eric D Nelson, Peter C Rasmussen, John B Stone, Stanley O Uptigrove

Publication number: 20110209786Abstract: The present invention discloses apparatuses, systems, and methods for utilizing oil-free gas in a gas processing system. In some embodiments, an oil-free or “dry” gas is provided by a gas source to an oil-free compressor, such as a dry seal compressor, which charges a receiver vessel or vessels, which then provides the oil-free gas to at least one piece of processing equipment, such as an injection compressor or compressors for use in EOR, carbon sequestration, sour gas injection, or other gas handling operations. The methods and systems may include a controller for charging the receiver vessel when the pressure in the vessel decreases below a low pressure threshold and reducing the charging flow rate when the pressure in the vessel meets or exceeds a high pressure threshold in the vessel, thereby maintaining an operational pressure in the vessel.Type: ApplicationFiled: August 19, 2009Publication date: September 1, 2011Inventors: Peter C.
