  • ETHANOL SEPARATION PROCESS HAVING STRIPPING SECTION FOR REDUCING ACETALS
    Publication number: 20130032466
    Abstract: To reduce acetal concentrations when separating ethanol from a crude product in one or more distillation column, at least one of the columns has a stripping section that comprises at least 40 stages to favor hydrolysis of the acetal. The crude product may comprise ethanol, acetaldehyde, water and one or more acetals, such as diethyl acetal. The acetal concentration may be reduced thus reducing the need to separate acetal from the crude product.

    Publication number: 20130035523
    Abstract: To reduce acetal concentrations when separating ethanol from a crude product in one or more distillation column, at least one of the columns is operated at a higher pressure to increase the equilibrium constant that favors hydrolysis of the acetal. The crude product may comprise ethanol, acetaldehyde, water and one or more acetals, such as diethyl acetal. The acetal concentration may be reduced thus reducing the need to separate acetal from the crude product.

  • Processes for Separating Ethanol Having Low Acid
    Publication number: 20130035522
    Abstract: A process for reducing ethyl acetate and/or diethyl acetal concentration of a crude ethanol product by hydrolysis is disclosed. A portion of the water is initially separated from the crude ethanol product in a first column residue. Ethyl acetate in the first column distillate is hydrolyzed to form additional ethanol and acetic acid. Product ethanol is recovered in a second distillation column preferably in a side stream and acetic acid is removed in the second column residue.

  • VAPOR SEPARATION IN ALCOHOL PRODUCTION
    Publication number: 20130032467
    Abstract: Two or more vapor-liquid separators are used in a process for removing at least one non-condensable gas from a crude alcohol mixture prepared by hydrogenating alkanoic acid and/or esters thereof. The vapor-liquid separators may comprise flashers or knock-out pots and are suitable for removing non-condensable gas, including those gases that are dissolved in the liquid. The multiple vapor-liquid separators may be in series prior to any separation of organic components. In addition, there may be a vapor-liquid separator before and after a distillation column for treating the feed to the column.
