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®, EthylMercaptan (EM), and THT (TetraHydroThiophene).

Arkema also offers multiple odor control agents. The first is O-Scent, which is a highly effective airborne odor neutralizer that comes in a standard formulation called O-Scent OC, and a low-temperature formula called O-Scent AF. The other odor control product is Mercaptan Assassin®, which is sold as a kit containing Mercaptan Assassin ESD and Mercaptan Assassin™ AOT. The Mercaptan Assasin® system is used to clean up mercaptan spills, treat empty drums, and remove mercaptan from fabric or clothing. Similar to O-Scent, it is effective for foul odor "emergencies" where both instant and long-lasting odor control are desired. It is safe to be used around people, domesticated animals, plants and marine life.

Investment in health, environment and safety

  • Upgraded equipment to eliminate TSS permit exceedances at stormwater 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.
