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.
