Abstract: There are inherent safety considerations associated with handling of natural gas. A very significant risk is that natural gas is generally odorless and colorless. Because of these properties natural gas goes through a process known as odorization to give the gas the typical gassy smell that people associate with natural gas. In a new pipeline, odor fade occurs when natural gas is stripped of its odor, thereby posing a risk since a potential leak would not be noticeable by smell. The primary focus of odorization is safety. Safety must be the primary goal and be kept in mind as we develop, maintain and improve our odorization techniques and processes. The startup of a newly installed steel pipeline carries the most risk for under-odorization or over-odorization, and it is up to the operator to balance this concern. This paper will describe odor fade in a natural gas pipeline and discuss a pre- odorization step known as pickling used to overcome this odor fade issue.
