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 xide 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

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

Global cement production accounts for 7% of annual greenhouse gas emissions worldwide. It is made from limestone burned at high temperatures, releasing large amounts of CO 2.
