Pineville, Louisiana production plant

The Pineville, La. plant has grown into one of the premier suppliers of natural gas and propane odorants in North America for Arkema. The plant was founded in 1994 with the goal of providing odorant services to municipalities, natural gas pipeline companies and others. In July of 2008, Odor-Tech was acquired by Arkema Inc. Odor-Tech LLC merged into its parent company, Arkema Inc., January 1, 2019. As a result, the Odor-Tech name will no longer be used after 2018, and all odorant business going forward will be conducted under the name Arkema.

Products and markets

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


Another Arkema Odorants product, Mercaptan AssassinTM ESD, is used to clean up mercaptan spills, treat empty drums, and remove mercaptan from fabric or clothing. Mercaptan AssassinTM 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 AssassinTM ESD is safe to be used around people, domesticated animals, plants and marine life.

A compatible product, Mercaptan AssassinTM 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 2018

Investment in health, environment and safety


  • Upgraded equipment to eliminate TSS permit exceedances at storm water outfall
  • Upgraded delivery fleet to reduce sources of leaks
  • State-of-the-art "closed-loop" delivery system utilized. 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

17 years no recordable / 17 years no loss of primary containment.
