US Patent:
8552224, Oct 8, 2013
Filed:
Nov 5, 2010
Appl. No.:
12/940595
Inventors:
Trinity Horton - Houston TX, US
Radmila Jevtic - Houston TX, US
Victor J. Johnston - Houston TX, US
Tianshu Pan - Houston TX, US
R. Jay Warner - Houston TX, US
Heiko Weiner - Pasadena TX, US
Nathan Bower - Houston TX, US
Josefina T. Chapman - Houston TX, US
Gerald Grusendorf - Rosharon TX, US
Assignee:
Celanese International Corporation - Dallas TX
International Classification:
C07C 29/149
US Classification:
568885, 568913, 568918
Abstract:
In one embodiment, the invention is to a process for purifying a crude ethanol product. The process comprises the step of hydrogenating acetic acid in a reactor in the presence of a catalyst to form the crude ethanol product. The process further comprises the step of separating at least a portion of the crude ethanol product in a purification zone. The purification zone preferably comprises a first column, which yields a first distillate comprising ethanol, water and ethyl acetate, and a first residue comprising acetic acid. The at least a portion of the crude ethanol product has a residence time from the reactor to the purification zone from 5 minutes to 5 days.

US Patent:
8569551, Oct 29, 2013
Filed:
Apr 26, 2011
Appl. No.:
13/094580
Inventors:
Radmila Jevtic - Pasadena TX, US
Victor J. Johnston - Houston TX, US
Tianshu Pan - Houston TX, US
Mark O. Scates - Houston TX, US
Ronald David Shaver - Houston TX, US
R. Jay Warner - Houston TX, US
Heiko Weiner - Pasadena TX, US
Josefina T. Chapman - Houston TX, US
Assignee:
Celanese International Corporation - Dallas TX
International Classification:
C07C 29/80
US Classification:
568885
Abstract:
In one embodiment, the invention is to a process for producing ethanol, comprising the step of providing from a distillation column in a carbonylation process a purified acetic acid stream comprising up to 25 wt. % water. The process further comprises the step of hydrogenating acetic acid of the purified acetic acid stream in the presence of a catalyst and under conditions effective to form a crude ethanol product comprising ethanol and water. Ethanol is recovered from the crude ethanol product.

Characterizing Powders Using Frequency-Domain Photon Migration

View page
US Patent:
20030117622, Jun 26, 2003
Filed:
Oct 21, 2002
Appl. No.:
10/274790
Inventors:
Zhigang Sun - Houston TX, US
Tianshu Pan - College Station TX, US
International Classification:
G01N021/00
US Classification:
356/338000
Abstract:
Characterizing a powder bed includes generating measurements by repeating the following. A location of the powder bed is illuminated with light having a time varying intensity with a resolution of less than one hundred nanoseconds. The particles scatter the light to alter the time varying intensity. The light propagates through a portion of the particles that defines a sampled volume. The light received from the powder bed is detected. The altered time-varying intensity of the light is measured to generate a time-dependent signal having a time-dependence that is less than or equal to a time-of-flight of a photon of the propagating light. An optical property is determined from the time-dependent signal, and a characteristic is determined from the optical property. The sampled volume is determined, and variance of the measurements is calculated. Uniformity of the powder bed is determined in accordance with the variance and the sampled volume.

Assignee:
CELANESE INTERNATIONAL CORPORATION - Dallas TX
International Classification:
C07C 29/74
C07C 29/80
US Classification:
568884
Abstract:
Purifying and/or recovery of ethanol from a crude ethanol product obtained from the hydrogenation of acetic acid from an feed stream comprising water. The presence of water does not significantly impact acid conversion or selectivity to ethanol. Further the addition of water allows for improved recovery of ethanol.
