NOVELTY - Separating ethanol from ethanol laden beer involves: fermenting a mixture of water and milled grain to produce ethanol laden beer; distilling in a beer column maintained at a pressure below atmospheric pressure by a condenser; evaporating water from the thin stillage to produce mid stillage (S1) and first effect steam (F1); evaporating water from (S1) with heat from the (F1) to produce second effect steam (F2) and byproducts including a syrup; using the (F2) to supply sufficient heat for the distillation in beer column.    USE - For distilling ethanol (Claimed) particularly motor fuel grade ethanol. This ethanol is also useful as a gasoline additive for formulating clean burning grades of gasoline for motor vehicles.    ADVANTAGE - The ethanol distillation process arrangement uses a minimum of energy and operates with a minimum of down time. In this method, low temperature steam produced by the second effect evaporators is used to heat the beer column, as a result no reboiler is needed and that column need not be cleaned over very long periods of time that may even extend through the life of a plant. This significantly reduces the amount of time that an ethanol distillation facility must be shut down. Thus the process is capable of operating continuously in a steady state condition for many months, even when an evaporator a component that is most often in need of periodic cleaning is isolated and cleaned. This provides significant economic advantages to a facility operator; improves the economics of fuel grade ethanol distillation and yields significant value in a growing industry.    DETAILED DESCRIPTION - Separating ethanol from ethanol laden beer involves: fermenting a mixture of water and milled grain to produce ethanol laden beer; distilling in a beer column maintained at a pressure below atmospheric pressure by a condenser to produce: a vapor primarily including ethanol which is condensed by the condenser into a liquid primarily including ethanol and byproducts including thin stillage, contains primarily water; evaporating water from the thin stillage to produce mid stillage (S1) and first effect steam (F1); evaporating water from (S1) with heat from the (F1) to produce second effect steam (F2) and byproducts including a syrup; using the (F2) to supply sufficient heat for the distillation in beer column.
