Patent number: 9079846Abstract: A process for oxidizing solid crude terephthalic acid is described. The process includes contacting solid crude terephthalic acid with a solvent comprising a carboxylic acid and one or more of an ionic liquid or ammonium acetate; a bromine source; a catalyst; and an oxidizing agent to produce solid purified terephthalic acid at a temperature of about 100 to about 210° C., and a pressure of about 2 to about 4.5 MPa, for a time of about 5 to about 60 min, and recovering the solid purified terephthalic acid.Type: GrantFiled: October 12, 2012Date of Patent: July 14, 2015Assignees: UOP LLC, BORESKOV INSTITUTE OF CATALYSIS SIBERIAN BRANCH OF THE RUSSIAN ACADEMY OF SCIENCESInventors: Alakananda Bhattacharyya, Nina Kuznetsova, Bair S.

Publication number: 20140163294Abstract: One exemplary embodiment can be a process for removing one or more sulfur compounds from a first liquid. The process can include passing the first liquid through a first inlet and a second liquid through a second inlet, and passing the first liquid through a first outlet and the second liquid through a second outlet of a vessel. The vessel may further have a plurality of vortex contactors. Often, the plurality of vortex contactors has a first vortex contactor, in turn including at least one wall and a frustum. The at least one wall can form a perimeter about an interior space and include a first side and a second side forming a passageway communicating the first liquid from an exterior to the interior space, and a frustum positioned proximate to the passageway and abutting the at least one wall for facilitating contacting of the first and second liquids to extract the one or more sulfur compounds from the first liquid to the second liquid.Type: ApplicationFiled: December 10, 2012Publication date: June 12, 2014Applicants: Boreskov Institute of Catalysis, Siberian Branch of Russian Academy of Sciences, UOP LLCInventors: Aziz Sattar, Daniel K. Aiken, Andrey Kuzmin

Publication number: 20140160879Abstract: One exemplary embodiment can be an apparatus for contacting a first liquid and a second liquid. The apparatus can include a vessel. The vessel can include a wall and a funnical frustum. The wall may form a perimeter about an interior space and include a first side and a second side forming a passageway communicating at least one of the first and second liquids to the interior space. The funnical frustum may be positioned proximate to the passageway and abut the wall for facilitating contacting of the first and second liquids.Type: ApplicationFiled: December 10, 2012Publication date: June 12, 2014Applicants: Boreskov Institute of Catalysis, Siberian Branch of Russian Academy of Sciences, UOP LLCInventors: Andrey Kuzmin, Aziz Sattar, Lev Davydov

Publication number: 20140163295Abstract: One exemplary embodiment can be a process for extracting one or more sulfur compounds. The process may include mixing a hydrocarbon stream containing the one or more sulfur compounds with an alkaline stream in at least one vessel. Often, the at least one vessel includes a member forming a perimeter about an interior space and having a first side and a second side forming a passageway communicating at least one of the hydrocarbon stream and the alkaline stream from an outer surface of the member to the interior space, and a frustum. The frustum can be positioned proximate to the passageway and abutting the member for facilitating contacting of the hydrocarbon stream and the alkaline stream.Type: ApplicationFiled: December 10, 2012Publication date: June 12, 2014Applicants: Boreskov Institute of Catalysis, Siberian Branch of Russian Academy of Sciences, UOP LLCInventors: Lev Davydov, Daniel K.
