Patent number: 7010937Abstract: A process for liquefying natural gas in conjunction with producing a liquid stream containing predominantly hydrocarbons heavier than methane is disclosed. In the process, the natural gas stream to be liquefied is partially cooled, expanded to an intermediate pressure, and supplied to a distillation column. The bottom product from this distillation column preferentially contains the majority of any hydrocarbons heavier than methane that would otherwise reduce the purity of the liquefied natural gas. The residual gas stream from the distillation column is compressed to a higher intermediate pressure, cooled under pressure to condense it, and then expanded to low pressure to form the liquefied natural gas stream.Type: GrantFiled: April 13, 2004Date of Patent: March 14, 2006Assignee: ElkCorpInventors: John D. Wilkinson, Hank M. Hudson, Kyle T. Cueller

Patent number: 6936329Abstract: A fastener-free composite roofing product comprising a roofing material and an interply material attached to the roofing material, wherein the interply material includes an adhesive coating on one side. The interply material is attached adjacent to an edge of the roofing material to permit a major portion of the interply material to be folded away from the roofing material for application to a roof. The adhesive is effective to secure the roofing product to the roof without the use of nails or other fasteners. The roofing material may be a roofing shingle or roll roofing, and the interply material is comprised of a water resistant material.Type: GrantFiled: July 15, 2003Date of Patent: August 30, 2005Assignee: ElkCorp.Inventors: Matti Kiik, Michael Bryson, Micheal Allen McLintock, Kevin L.

Patent number: 6915662Abstract: A process for the recovery of ethane, ethylene, propane, propylene and heavier hydrocarbon components from a hydrocarbon gas stream is disclosed. In recent years, the preferred method of separating a hydrocarbon gas stream generally includes supplying at least portions of the gas stream to a fractionation tower having at least one reboiler, and often one or more side reboilers, to supply heat to the column by withdrawing and heating some of the tower liquids to produce stripping vapors that separate the more volatile components from the desired components. The reboiler and side reboilers (if any) are typically integrated into the feed stream cooling scheme to provide at least a portion of the refrigeration needed to condense the desired components for subsequent fractionation in the distillation column.Type: GrantFiled: October 26, 2001Date of Patent: July 12, 2005Assignee: ElkCorp.Inventors: John D. Wilkinson, Hank M. Hudson, Michael C. Pierce

Patent number: 6889523Abstract: A process for liquefying natural gas in conjunction with processing natural gas to recover natural gas liquids (NGL) is disclosed. In the process, the natural gas stream to be liquefied is taken from one of the streams in the NGL recovery plant and cooled under pressure to condense it. A distillation stream is withdrawn from the NGL recovery plant to provide some of the cooling required to condense the natural gas stream. A portion of the condensed stream is expanded to an intermediate pressure and then used to provide some of the cooling required to condense the natural gas stream, and thereafter routed to the NGL recovery plant so that any heavier hydrocarbons it contains can be recovered in the NGL product. The remaining portion of the condensed stream is expanded to low pressure to form the liquefied natural gas stream.Type: GrantFiled: March 7, 2003Date of Patent: May 10, 2005Assignee: ElkCorpInventors: John D. Wilkinson, Hank M. Hudson, Kyle T. Cuellar

Publication number: 20040258883Abstract: A laminated roofing shingle has an increased nailing zone obtained by increasing the width of the backer strip and thinning a portion of the extended backer strip underlying the nailing zone on the upper shingle layer. The thinned portion is of a width such that when a pair of the shingles are stacked one atop the other with their respective backer strips oriented in opposite directions, the respective thinned portions are aligned with one another and are separated only by the upper shingle layer of the lowermost shingle. When stacked and bundled, the extended backer strip portions do not substantially increase the height of the bundle. The height of the bundle may be further reduced by forming a longitudinally extending thinned area in the upper shingle layer overlying the thinned portion of the backer strip.Type: ApplicationFiled: June 17, 2003Publication date: December 23, 2004Applicant: ElkCorp.Inventor: Casimir Paul Weaver
