Patent number: 10029973Abstract: Disclosed is an optimized process and apparatus for more efficiently and economically carrying out the liquid-phase oxidation of an oxidizable compound. Such liquid-phase oxidation is carried out in a bubble column reactor that provides for a highly efficient reaction at relatively low temperatures. When the oxidized compound is para-xylene and the product from the oxidation reaction is crude terephthalic acid (CTA), such CTA product can be purified and separated by more economical techniques than could be employed if the CTA were formed by a conventional high-temperature oxidation process.Type: GrantFiled: November 24, 2017Date of Patent: July 24, 2018Assignee: GROPO PETROTEMEX, S.A. DE C.V.Inventors: Alan George Wonders, Robert Lin, Lee Reynolds Partin, Marcel de Vreede, Wayne Scott Strasser

Patent number: 8734909Abstract: Methods and apparatus for coating substrates. A die can be employed for extrusion coating an elongated substrate, where the die defines a coating cavity therein. The die can comprise a die block having a coating supply channel for supplying a coating material to the coating cavity. The die can further comprise a guide plug and a die plate removably coupled to the die block. The guide plug can comprise a substrate inlet having a non-circular lateral cross-section, and the die plate can comprise a substrate outlet also having a non-circular lateral cross-section. A coating system comprising such a die can operate to coat a substrate where the substrate can be pushed at least partially through the die and contacts the coating material therein.Type: GrantFiled: March 10, 2010Date of Patent: May 27, 2014Assignee: Eastman Chemical CompanyInventors: Subramanian Easwaran Iyer, Jeremy Richard Lizotte, William Joseph Burgess, Wayne Scott Strasser, James Wilson Mercer, Jr., Tony Wayne Helton, Gary Darrel Boone
