Pineville, Louisiana production plant

The Pineville, LA Odor-Tech LLC plant has grown into one of the premier suppliers of natural gas and propane odorants in North America.

The plant was founded in 1994 with the stated goal of providing odorant services to municipalities, natural gas pipeline companies and others. In July of 2008, Odor-Tech was acquired by Arkema Inc.

Distributors of utilities for consumer use are required by law to odorize natural gas and propane to assist in detecting possible leaks, lessening the risk of natural gas explosions. To this end, Odor-Tech offers product lines for use in both natural gas and propane/butane, including various blends of Spotleak®, ethyl mercaptan (EtSH) and tetrahydrothiophene (THT).

Another product, Mercaptan Assassin™ ESD, is used to clean up mercaptan spills, treat empty drums, as well as removing mercaptan from fabric or clothing. Mercaptan Assassin™ ESD digests mercaptans, proteins, carbohydrates, cellulose, fats, oils, uric salts and grease. It is particularly effective for foul odor "emergencies" where both instant and long-lasting odor control are desired. Mercaptan Assassin™ ESD is safe to be used around people, domesticated animals, plants and marine life.


A compatible product, Mercaptan Assassin™ AOT, is used to treat airborne odors. With just one or two mists, even the most offensive odors are cleared away, leaving a pleasant citrus smell.

Key figures for 2015

# of employees 15
Local economic impact (payroll/utility/property taxes paid annually) $880,000 in 2015
Investment in health, environment and safety ● Odor-Tech uses a state-of-the-art "closed loop" delivery system. In traditional "flared" delivery, excess vapors are burned off creating sulfur dioxide, raising environmental concerns and resulting in a powerful aroma. Odor-Tech’s closed-loop delivery system eliminates excess vapors and results in a safer, odor-free, delivery.
● Each of the storage tanks on the Pineville site is surrounded by a secondary, welded-steel containment structure that can hold the entire contents of the tank in the event of an emergency.
Safety record  No injuries in the last 15 years that led to lost work time.
Awards/Certifications for safety, environmental, and quality ● The American Chemistry Council awarded Odor-Tech with the Responsible Care® Award for Employee Health and Safety for 2008 and 2009; and Certificate of Excellence for 2011.
● Earned Arkema’s Outstanding Safety Performance Award in both 2008 and 2009.
