Filed:

Apr 28, 2005
Appl. No.:

11/116771
Inventors:

Raymond J. Zinobile - Houston TX, US
Mark O. Scates - Houston TX, US
Jonathan A. Makelki - Bay City TX, US
Manuel Salado - Seabrook TX, US
Assignee:

Celanese International Corporation - Pasadena TX
International Classification:

C07C 51/42
US Classification:

562608
Abstract:

A process for the reduction and/or removal of permanganate reducing compounds formed by the carbonylation of methanol in the presence of a Group VIII metal carbonylation catalyst to produce acetic acid is disclosed. More specifically, a process for reducing and/or removing permanganate reducing compounds or their precursors from intermediate streams during the formation of acetic acid by said carbonylation processes is disclosed. In particular, a process in which a low boiling overhead vapor stream from a light ends column is subjected to a single distillation to obtain an overhead that is subjected to an extraction to selectively remove and/or reduce PRC's from the process is disclosed.

Filed:

Apr 20, 2007
Appl. No.:

11/788455
Inventors:

Mark O. Scates - Houston TX, US
David A. Trueba - Webster TX, US
Raymond J. Zinobile - Houston TX, US
Assignee:

Celanese International Corporation - Dallas TX
International Classification:

C07C 51/10
C07C 51/42
C07C 45/78
US Classification:

562519, 562608
Abstract:

An improvement of the methanol carbonylation process for manufacturing acetic acid is disclosed. Specifically disclosed is a method for reducing the formation of alkyl iodides and Ccarboxylic acids by removing permanganate reducing compounds (“PRC's”) from the light phase of the condensed light ends overhead stream, including (a) distilling the light phase to yield a PRC enriched overhead stream; and (b) extracting the third overhead stream with water in at least two consecutive stages and separating therefrom one or more aqueous streams containing PRC″s.

Filed:

Apr 23, 2009
Appl. No.:

12/386808
Inventors:

Raymond J. Zinobile - Houston TX, US
Tommy W. Doggett - League City TX, US
Assignee:

Celanese International Corporation - Dallas TX
International Classification:

C07C 51/12
C07C 51/42
US Classification:

562519, 562608
Abstract:

A methanol carbonylation system includes an absorber tower adapted for receiving a vent gas stream and removing methyl iodide therefrom with a scrubber solvent, the absorber tower being coupled to first and second scrubber solvent sources which are capable of supplying different first and second scrubber solvents. A switching system including valves alternatively provides first or second scrubber solvents to the absorber tower and returns the used solvent and sorbed material to the carbonylation system to accommodate different operating modes.

Filed:

Aug 16, 2010
Appl. No.:

12/857323
Inventors:

Raymond J. Zinobile - Houston TX, US
Ronald David Shaver - Houston TX, US
Assignee:

Celanese International Corporation - Dallas TX
International Classification:

C07C 51/42
C07C 51/44
C07B 63/00
US Classification:

562519, 562517
Abstract:

The present invention is directed to a method of heating a light ends column through directing one or more vapor side streams from a drying column to the light ends column. The present invention is also directed to a carbonylation process for producing acetic acid, wherein one or more vapor streams from a drying column provide the external energy required to drive separation in the light ends column.

Assignee:

Celanese International Corporation - Dallas TX
International Classification:

C07C 51/10
US Classification:

562517
Abstract:
