  • Patent number: 4490153
    Abstract: Low energy process for the production of gasoline-ethanol blends, comprising dehydrating the aqueous ethanolic product from a conventional fermentation process, preferably containing about 6 wt. % ethanol, so as to generate an aqueous ethanolic effluent containing about 90 wt. % ethanol; mixing the effluent with gasoline feedstock; chilling the resultant gasoline-aqueous ethanol mixture to a temperature of about -10.degree. F., without forming ice, thereby to form (1) a gasohol blend containing about 10 wt. % ethanol and (2) an aqueous stream comprising some ethanol and traces of gasoline; extracting the gasoline-containing aqueous stream with a minor stream of the fermentation ethanol product in order to recover the gasoline it contains; and recovering said blend to produce a gasohol product under-saturated with water at all operating temperatures above -10.degree. F.
