    • In one embodiment, the disclosure includes a method of biomass conversion including fermenting biomass to produce a carboxylic acid or carboxylate salt and hydrogen gas, recovering the hydrogen gas, and converting the carboxylic acid or carboxylate salt to an alcohol using the hydrogen gas. In one embodiment, the hydrogen produced by biomass conversion may be converted to an acetate. Another embodiment relates to a biomass conversion system. The system may include: a fermentation unit for fermentation of biomass to a carboxylic acid or carboxylate salt in a fermentation broth and for production of a carbon dioxide and hydrogen gas stream, an extraction unit for extracting the carboxylic acid or carboxylate salt from the fermentation broth, a gas extraction unit for separation of the hydrogen gas and the carbon dioxide, and a production unit for production of an alcohol from the carboxylic acid or carboxylate salt using the hydrogen gas.

    • According to one embodiment of the invention, a vapor-compression evaporation system includes a plurality of vessels in series each containing a feed having a nonvolatile component. A first set of the plurality of vessels includes vapor­ compression evaporators and a second set of the plurality of vessels includes multi­effect evaporators. A mechanical compressor is coupled to the last vessel in the series of vapor-compression evaporators and is operable to receive a vapor therefrom. A turbine is coupled to, and operable to drive, the mechanical compressor. A pump is operable to deliver a cooling liquid to the mechanical compressor, and a tank is coupled to the mechanical compressor and is operable to separate liquid and vapor received from the mechanical compressor. A plurality of heat exchangers is coupled inside respective ones of the vessels, wherein the heat exchanger in the first vessel in the first set is operable to receive the vapor from the tank, and at least some of the vapor condenses therein. The heat of condensation provides the heat of evaporation to the first vessel in the first set, and at least some of the vapor inside the first vessel in the first set is delivered to the heat exchanger in the next vessel in the first set, whereby the condensing, evaporating, and delivering steps continue until the last vessel in the second set is reached.
