Mercaptan
Mercaptan is a chemical compound that's extremely important in the gas industry. It's the substance that gives natural gas its distinctive "rotten egg" smell, as natural gas is actually odorless by itself. Gas companies add mercaptan as a safety measure so people can detect gas leaks easily. When you see this term on a resume, it usually indicates experience with gas safety, quality control, or handling of odorants in natural gas processing. Other names for this compound include "methanethiol" or "natural gas odorant."
