Emissions of SO2 from natural gas-fired boilers are low because pipeline quality natural gas typically has sulfur levels of 2,000 grains per million cubic feet. However, sulfur-containing odorants are added to natural gas for detecting leaks, leading to small amounts of SO2 emissions. Boilers
temperature ranges of 975-1300 ℃ and gas residence times 0.5-2.0s . Since the combustion process in the RF provides substantial sulfur recovery and affects the entire plant emissions, any modification in the RF affects sulfur conversion and emissions such as COS, CS 2

Sulfur dioxide (aka sulfurous anhydride, sulfurous oxide) is a colorless gas with a choking or suffocating odor. Its use as a fumigant dates back to ancient Greece. Note this passage from The Odyssey, where Odysseus says: Bring sulfur, old nurse, that cleanses all pollution, and bring me fire, that I may purify the house with sulfur
The sulfur in the natural gas may then be burned by the end user with the formation of sulfur dioxide (SO2), typically in low ppm or even ppb levels. Once the natural gas reaches saturation, any additional pressure drop and/or cooling will result in additional deposition. This can be a very big problem for cryogenic facilities such as LNG plants.
