An energy-efficient extractive distillation process for producing anhydrous ethanol from aqueous/ethanol feeds containing any range of ethanol employs an extractive distillation column (EDC) that operates under no or greatly reduced liquid reflux conditions. The EDC can be incorporated into an integrated process for producing anhydrous ethanol used for gasoline blending from fermentation broth. By using a high-boiling extractive distillation solvent, no solvent is entrained by the vapor phase to the EDC overhead stream, even under no liquid reflux conditions. The energy requirement and severity of the EDC can be further improved by limiting ethanol recovery in the EDC. In this partial ethanol recovery design, ethanol which remains in the aqueous stream from the EDC is recovered in a post-distillation column or the aqueous stream is recycled to a front-end pre-distillation column where the ethanol is readily recovered since the VLE curve for ethanol/water is extremely favorable for distillation.

A method and apparatus for conditioning ambient air for use in an enclosure is disclosed which cools the ambient supply air stream in sensible energy recovery device or cools and dehumidifies the ambient supply air stream in an enthalpy energy recovery device. The thus cooled air is then cooled by a cooling coil of a refrigerant cooling system to reduce its temperature and humidity. The thus cooled and dehumidified air is then passed through a segment of a rotating desiccant wheel or through a different type of desiccant dehumidification device under conditions which reduce its moisture content and increases its temperature. The supply air is then delivered from the desiccant wheel to the enclosure. The desiccant wheel is regenerated by heating a separate regeneration air stream, provided by the exhaust air from the space and using the condensing coil of the refrigerant system to increase the regeneration air stream temperature. The thus heated regeneration air stream is then passed through another segment of the rotating desiccant wheel to regenerate the wheel and is exhausted to the atmosphere.
