Patent number: 11433351Abstract: A system and method for recovering carbon dioxide from a stream of gas using an absorption unit configured to receive the stream of gas and a stream of liquid absorbent. The gas includes carbon dioxide and vaporized water, and the liquid absorbent is chemically reactive with the carbon dioxide to form a solidified carbon dioxide-rich absorbent material. The gas and the liquid absorbent are mixed in the absorption unit such that a slurry that includes the solidified carbon dioxide-rich absorbent material and condensed water is formed therein. The system and method may also employ a transport mechanism coupled in communication with the absorption unit, wherein the transport mechanism is configured to channel the slurry downstream from the absorption unit.Type: GrantFiled: March 23, 2020Date of Patent: September 6, 2022Assignee: BAKER HUGHES COMPANYInventors: Tiffany Elizabeth Pinard Westendorf, Paul Russell Wilson, Rachel Lizabeth Farnum

Patent number: 6790929Abstract: This invention relates to an extrusion method preparing polycarbonates from a solution of an oligomeric polycarbonate. A mixture of bis(methyl salicyl)carbonate (BMSC), BPA and a transesterification catalyst are first equilibrated at moderate temperatures to provide a solution of polycarbonate oligomer in methyl salicylate. The solution is then fed to a devolatilizing extruder, where the polymerization reaction is completed and the methyl salicylate solvent is removed. The solution comprising the oligomeric polycarbonate can also be pre-heated under pressure to a temperature above the boiling point of methyl salicylate and subsequently fed to a devolatilizing extruder equipped for rapid flashing off the solvent. The method provides polycarbonate with greater efficiency than the corresponding process in which unreacted monomers are fed to the extruder. Additionally, the method of the invention does not require the isolation of a precursor polycarbonate comprising ester-substituted phenoxy terminal groups.Type: GrantFiled: March 17, 2003Date of Patent: September 14, 2004Assignee: General Electric CompanyInventors: Norberto Silvi, Mark Howard Giammattei, Patrick Joseph McCloskey, Alberto Nisoli, James Day, Narayan Ramesh, Paul Michael Smigelski, Jr., Paul Russell Wilson
