Patent number: 8821696Abstract: Embodiments of extraction unit and an analysis method are provided. In one embodiment, the analysis method includes the steps of providing a feed stream and a species-selective solvent to the distillation column, drawing a vapor sample from the distillation column, condensing the vapor sample, and analyzing at least a portion of the condensed vapor sample.Type: GrantFiled: November 8, 2013Date of Patent: September 2, 2014Assignee: UOP LLCInventors: Jason L. Noe, Ian Horn, Lars Sullivan, Bruce R. Beadle, Edward M. Casey, James W. Harris

Publication number: 20140216915Abstract: The invention is a process and apparatus for removing a contaminant from an aromatic selective solvent. A feed stream comprising an aromatic hydrocarbon and a non-aromatic hydrocarbon is contacted with the aromatic selective solvent in an extractive distillation zone to produce a raffinate stream comprising the non-aromatic hydrocarbon, and a rich solvent stream comprising the aromatic hydrocarbon and the solvent. The rich solvent stream is separated in a second distillation zone to produce an extract stream comprising the aromatic hydrocarbon, and a lean solvent stream comprising the contaminant and the aromatic selective solvent. At least a portion of the lean solvent stream is washed with a non-aromatic hydrocarbon to produce a clean solvent stream, at least a portion of which is passed to at least one of the extractive distillation zone and the second distillation zone.Type: ApplicationFiled: April 4, 2014Publication date: August 7, 2014Applicant: UOP LLCInventors: Jason L. Noe, Lawrence E. Sullivan, Bruce R. Beadle, Edward M. Casey, Thomas J. Stoodt

Patent number: 7638669Abstract: Processes and apparatus are provided that provide high yields of xylenes per unit of aromatic-containing feed while enabling a high purity benzene co-product to be obtained without the need for an extraction or distillation to remove C6 naphthenes. The processes of this invention include a transalkylation section and a disproportionation section in the benzene and toluene-containing feed is directly provided to the transalkylation section and in which a benzene recycle loop in the transalkylation section isolates the disproportionation section from C6 naphthenes.Type: GrantFiled: June 25, 2008Date of Patent: December 29, 2009Assignee: UOP LLCInventors: Edward M. Casey, Patrick J. Silady, Antoine Negiz, Gregory R. Werba
