A sugar refining process uses carbon dioxide obtained from a module containing a plurality of gas-permeable polymeric membranes. Flue gas from a boiler is scrubbed, and then passed through the gas-separation module. The output of the module contains an enhanced concentration of carbon dioxide, in the range of about 20% by volume. The carbon dioxide enhanced gas is then directed into a reactor in which raw sugar is exposed to carbon dioxide to cause carbonation, an essential step in the decolorization of the raw sugar. The same boiler used to produce the carbon dioxide is also used to produce steam which drives the reaction. The present invention provides carbon dioxide for carbonation in a highly efficient manner, as the gas separation membrane has no moving parts and requires little maintenance. The invention is especially suited for retrofitting existing sugar refining plants, to improve their efficiency, at a relatively small cost.

Conventionally, sugarcane processing avoids leaving residual sucrose in the bagasse, since the bagasse will be burned and the value of the sucrose would be lost. However, when coupled with a Green Power+® process to extract hemicelluloses, sucrose may also be extracted and recovered from the bagasse. In some variations, a process includes mechanically treating a feedstock to generate a sucrose-rich stream and lignocellulosic material that intentionally retains a significant amount of the initial sucrose in the feedstock; extracting the lignocellulosic material with steam and / or hot water to produce cellulose-rich solids and an extract liquor containing hemicellulosic oligomers and sucrose; and then hydrolyzing the hemicellulosic oligomers into a hemicellulose sugar stream. Each of the sucrose-rich stream and the hemicellulose sugar stream (containing the starting residual sucrose) may be recovered or further processed (e.g., fermented to ethanol). Similar processes are possible with energy cane, sugar beets, and energy beets.
