Publication number: 20120253084Abstract: A process for producing ethanol comprising the steps of hydrogenating an acetic acid feed stream to form a crude ethanol product and separating at least a portion of the crude ethanol product to form an ethanol stream and at least one vent stream. The vent stream comprises non-condensable gases at least one volatile organic. The process further comprises the step of scrubbing the vent stream with at least two different solvents to recover the volatile organics. The vent stream may also comprise entrained ethanol, which may also be recovered.Type: ApplicationFiled: April 1, 2011Publication date: October 4, 2012Applicant: CELANESE INTERNATIONAL CORPORATIONInventors: Gerald Grusendorf, Victor J. Johnston, Fred Ronald Olsson, Wayne D. Picard, Nathan Powell, Samuel Roundy, Ismael Tejeda, James Curtis

Publication number: 20120035400Abstract: In one embodiment, the invention is to a process for producing ethanol. The process comprises the step of hydrogenating an acetic acid feed stream in a first reactor to form a crude ethanol product. The crude ethanol product may comprise, among other components, ethanol, acetaldehyde, and residual acetic acid. The process further comprises the step of recovering acetaldehyde from the crude ethanol product. The process further comprises the steps of feeding a first portion of the recovered acetaldehyde to the first reactor and reacting the first portion of the recovered acetaldehyde in the first reactor to form additional ethanol. In addition, the inventive process may comprise the steps of feeding a second portion of the recovered acetaldehyde to a second reactor and reacting the second portion of the recovered acetaldehyde in the second reactor to faun an additional product.Type: ApplicationFiled: August 3, 2011Publication date: February 9, 2012Applicant: Celanese International CorporationInventors: Victor J. Johnston, Tianshu Pan, Lincoln Sarager, R. Jay Warner, Heiko Weiner, Josefina Chapman, Robert Cunningham, Gerald Grusendorf, Trinity Horton, Radmila Jevtic

Publication number: 20110275865Abstract: Purifying and/or recovery of ethanol from a crude ethanol product obtained from the hydrogenation of acetic acid. Separation and purification processes of crude ethanol mixture are employed to allow recovery of ethanol and remove impurities. In particular, light ends are separated in an acetaldehyde removal column operating at a pressure greater than atmospheric pressure to recover acetaldehyde that may be returned to the reactor and reduce acetaldehyde concentrations in an ethyl acetate stream.Type: ApplicationFiled: April 1, 2011Publication date: November 10, 2011Applicant: CELANESE INTERNATIONAL CORPORATIONInventors: R. Jay Warner, Heiko Weiner, Nathan Bower, Josefina T. Chapman, Gerald Grusendorf, Radmila Jevtic, Victor J. Johnston

Publication number: 20110275863Abstract: 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.Type: ApplicationFiled: November 5, 2010Publication date: November 10, 2011Applicant: Celanese International CorporationInventors: Trinity Horton, Radmila Jevtic, Victor J. Johnston, Tianshu Pan, R. Jay Warner, Heiko Weiner, Nathan Bower, Josefina T. Chapman, Gerald Grusendorf

Publication number: 20110190550Abstract: In one embodiment, the present invention is to a process for producing a anhydrous ethanol composition comprising hydrogenating acetic acid in the presence of a catalyst to form a crude ethanol product; separating in a first column at least a portion of the crude ethanol product into a first distillate comprising ethanol, water and ethyl acetate, and a first residue comprising acetic acid; separating in a second column at least a portion of the first distillate into a second distillate comprising ethyl acetate and a second residue comprising ethanol and water; separating in a third column at least a portion of the second residue into a third distillate comprising ethanol and residual water and a third residue comprising separated water; and dehydrating at least a portion of the third distillate to form the anhydrous ethanol composition. The anhydrous ethanol composition, as formed, comprises less than 1 wt. % water, based on the total weight of the anhydrous ethanol composition.Type: ApplicationFiled: October 13, 2010Publication date: August 4, 2011Applicant: Celanese International CorporationInventors: Trinity Horton, Radmila Jevtic, Victor J.
