Patent number: 10759722Abstract: Aspects of the invention are associated with the discovery of approaches for the conversion of sour natural gas streams, by conversion to liquid hydrocarbons. Particular processes and their associated apparatuses advantageously combine (i) dehydroaromatization (DHA) of methane in a gaseous feedstock, to produce aromatic hydrocarbons such as benzene, with (ii) the reaction of H2S and methane in this feedstock, to produce organic sulfur compounds such as carbon disulfide (CS2) and thiophene (C4H4S). A gaseous product having a reduced concentration of H2S is thereby generated. The aromatic hydrocarbons and organic sulfur compounds may be recovered in a liquid product. Both the gaseous and liquid products may be easily amenable to further upgrading. Other advantages of the disclosed processes and apparatuses reside in their simplicity, whereby the associated streams, including a potential gaseous recycle, generally avoid high partial pressures of H2S.Type: GrantFiled: January 11, 2018Date of Patent: September 1, 2020Assignee: Gas Technology InstituteInventors: Terry Marker, Jim Wangerow, Dane Boysen, Martin B. Linck, Pedro Ortiz-Toral

Patent number: 7577536Abstract: The present invention provides a method for determining voltage loss in an electrical device. The method includes the steps of obtaining an array A of voltage values corresponding to at least one current interrupt measurement at current In, wherein In corresponds to current values I1, I2, . . . , In, wherein subscript n is at least 3; forming an array D of difference values using a difference of the array A over an elapsed time; processing the difference values of the array D to obtain Vn; determining Vn for each In to form an array V of Vn; and calculating a resistance, R, using the array V, thereby determining voltage loss in the electrical device.Type: GrantFiled: June 8, 2007Date of Patent: August 18, 2009Assignee: Superprotonic, Inc.Inventors: Calum Chisholm, Dane Boysen, Matt Hetterman, Alex Papandrew
