Clarion Technical Conferences has announced it will hold the Natural Gas Odorization International Conference & Exhibition in Houston, TX, on May 25-26, 2010. This is the first such meeting in several years and will cover all aspects of odorization.
A “Call for Papers” was issued inviting odorization experts from around the world to submit abstracts for review. More information can be found at http://www.clarion.org/naturalGas/naturalGas10/main.php.
Odorization requirements for gas pipelines can be found at 49 CFR 192.625. Distribution lines are required to be continuously odorized, transmission lines have varying requirements and in many cases are not odorized at all. Odorization is a complex operation that needs close attention to be effective.
PHMSA last amended the odorization regulations in 2003 to require odor testing be done with an instrument capable of measuring the gas-in-air concentration at which gas is readily detectable. “Readily detectable” can vary by person, so perhaps a definition of the concept is in order.
Readily detectable odor – an odor that can be discovered, determined or whose existence can be identified in a ready manner, without hesitating or much difficulty.
How do operators ensure their personnel understand this concept, so as to be able to report correctly when testing odor intensities? Perhaps a better way of understanding this idea of readily detectable is to put it in a different perspective. “The odor of gas should be one that a spouse, family, or member of the general public would quickly recognize, prompting them to take appropriate action.”

The Natural Gas Conference will explore this and all other facets of odorization from selecting an odorant, injection rates, testing and clean up.
