Publication number: 20080031789Abstract: 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: ApplicationFiled: August 29, 2007Publication date: February 7, 2008Applicant: EASTMAN CHEMICAL COMPANYInventors: Alan Wonders, Howard Jenkins, Lee Partin, Wayne Strasser, Marcel deVreede
