In ethanol production, there are two major point sources of CO 2 emissions. Carbon dioxide is produced at high purity (greater than 85% by volume [ii]) as an inherent byproduct of the fermentation process.CO 2 is also emitted during fuel burning, which has a relatively low CO 2 concentration consistent with typical flue gas compositions. The high-purity …Web

The gas stream next passes through a drying tower. A blower draws the gas from the drying tower and discharges the sulfur dioxide gas to the sulfur trioxide converter, then to the oleum tower and/or absorber. In a "wet gas plant", the wet gases from the combustion chamber are charged directly to the converter, with no intermediate treatment.Web
