Does gas transported have rotten egg smell?
Some natural gas pipelines have an odorant added known as mercaptan which has a smell resembling that of rotten eggs. Local distribution companies typically add this odorant so their customers can detect the presence of natural gas in the air.Spectra Energy is an interstate natural gas transmission pipeline company in the U.S. and not a local distribution company. Thus many of our pipelines are not odorized.If a leak were to occur in a pipeline that does not have mercaptan, a person might still detect a faint smell of hydrocarbons (propane and butane are other examples of hydrocarbons), not rotten eggs, even though natural gas is considered odorless.
