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.
