Patent number: 12222147Abstract: A trans-critical thermodynamic system includes an expansion device and a separator. The expansion device receives a supercritical fluid containing solutes. The expansion device is operable to expand the supercritical fluid to produce a sub-critical gas by reducing a temperature and/or a pressure of the supercritical fluid. The separator removes the solutes from the sub-critical gas.Type: GrantFiled: September 3, 2020Date of Patent: February 11, 2025Assignee: ROLLS-ROYCE plcInventors: Ian M Bunce, Chloe J Palmer

Patent number: 11927378Abstract: A sensor assembly is shown for sensing a crossing of the critical point in a system utilising a working fluid in a transcritical cycle passing through the critical point. A first broadband acoustic sensor is located upstream of a component and a second broadband acoustic sensor is located downstream of the component, each of which are arranged to detect high-frequency and low-frequency sounds caused by the crossing of the critical point. A flow regulation device regulates flow of working fluid through the component in response to the output of one or both of the first broadband acoustic sensor and the second broadband acoustic sensor, thereby adjusting the location of the crossing of the critical point.Type: GrantFiled: November 21, 2022Date of Patent: March 12, 2024Assignee: Rolls-Royce PLCInventors: Chloe J. Palmer, Ian M. Bunce

Patent number: 11111792Abstract: A turbomachine (105) configured to compress supercritical carbon dioxide is shown. The turbomachine comprises, in fluid flow series, an inlet (201), an inducerless radial impeller (202) having a plurality of blades, and a fully vaneless diffuser (203). The radius of the inlet (r0) is from 25 to 50 percent of the radius of the impeller (r2).Type: GrantFiled: February 22, 2019Date of Patent: September 7, 2021Assignee: ROLLS-ROYCE plcInventors: Martin N Goodhand, Ian M Bunce

Publication number: 20200063567Abstract: A turbomachine (105) configured to compress supercritical carbon dioxide is shown. The turbomachine comprises, in fluid flow series, an inlet (201), an inducerless radial impeller (202) having a plurality of blades, and a fully vaneless diffuser (203). The inlet is radially flared to induce a radial component in flow prior to an entry to the impeller.Type: ApplicationFiled: February 22, 2019Publication date: February 27, 2020Applicant: ROLLS-ROYCE plcInventors: Martin N.
