Patent number: 9447005Abstract: 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.Type: GrantFiled: August 19, 2013Date of Patent: September 20, 2016Assignee: CELANESE INTERNATIONAL CORPORATIONInventors: Trinity Horton Hale, Radmila Wollrab, Victor J. Johnston, Lincoln Sarager, R. Jay Warner, Gerald Grusendorf

Patent number: 9328044Abstract: 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: GrantFiled: September 16, 2013Date of Patent: May 3, 2016Assignee: CELANESE INTERNATIONAL CORPORATIONInventors: Trinity Horton Hale, Radmila Wollrab, Victor J. Johnston, Tianshu Pan, R. Jay Warner, Heiko Weiner, Nathan Bower, Josefina T. Chapman, Gerald Grusendorf

Patent number: 9102581Abstract: Recovery of ethanol from a crude ethanol product obtained from the hydrogenation of acetic acid. Separation and purification processes of crude ethanol product are employed to allow recovery of ethanol and remove impurities. In addition, the process involves separating the crude ethanol product using an extractive distillation column that employs an extraction agent, such as a recycled stream comprising water.Type: GrantFiled: October 4, 2012Date of Patent: August 11, 2015Assignee: Celanese International CorporationInventors: R. Jay Warner, Radmila Wollrab, Wael Amleh, Gerald Grusendorf, Trinity Horton Hale, Victor J. Johnston, Fred Ronaold Olsson, Nathan Kirk Powell, Manuel Salado, Lincoln Sarager
