US Patent:

20060047142, Mar 2, 2006

Filed:

Jun 16, 2005

Appl. No.:

11/153993

Inventors:

Alan Wonders - Kingsport TN, US
Howard Jenkins - Pendleton SC, US
Lee Partin - Kingsport TN, US
Wayne Strasser - Kingsport TN, US
Marcel de Vreede - Barendrecht, NL

International Classification:

C07C 51/265
B01J 8/18

US Classification:

562414000, 422140000, 422224000

Abstract:

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.

Appl. No.:

10/975256

Inventors:

Philip Gibson - Kingsport TN, US
Kenny Parker - Afton TN, US
Howard Jenkins - West Columbia SC, US

International Classification:

B01D 37/00

US Classification:

210702000, 210758000, 210784000

Abstract:

A process is disclosed that relates to the removal of impurities and the recovery of a mother liquor and wash filtrate from an oxidizer purge stream produced in the synthesis of carboxylic acid, typically terephthalic. More particularly, the process involves the removal of impurities and the recovery of a mother liquor and wash filtrate from an oxidizer purge stream and then routing the mother liquor and or wash filtrate to an oxidation zone.
