  • Process for heat integration for ethanol production and purification process
    Patent number: 9073814
    Abstract: Ethanol production from the hydrogenation of acetic acid requires energy to drive the hydrogenation reaction and the purification of the crude ethanol product. Heat integration process to recover heat from one part of the production process to be used within the process improves efficiencies and reduces costs.
    Type: Grant
    Filed: October 1, 2013
    Date of Patent: July 7, 2015
    Assignee: Celanese International Corporation
    Inventors: Nathan Kirk Powell, Samuel Roundy, Lincoln Sarager, Murray Viard, R. Jay Warner, Gerald Grusendorf, Radmila Wollrab, Victor J. Johnston, Fred Ronald Olsson

  • VENT SCRUBBERS FOR USE IN PRODUCTION OF ETHANOL
    Publication number: 20120253084
    Abstract: 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.
