1.4 Natural Gas Combustion

However, sulfur-containing odorants are added to natural gas for detecting leaks, leading to small amounts of SO2 emissions. Boilers combusting unprocessed natural gas may have higher SO2 emissions due to higher levels of sulfur in the natural gas. For these units, a sulfur mass balance should be used to determine SO2 emissions.

Lignosulfonates are complex polymers derived from trees. The wood from trees is composed mainly of three macromolecular components – cellulose, hemicellulose and lignin. In the sulfite pulping process, the lignins are sulfonated so they become water-soluble and thus can be separated from the insoluble cellulose.
