FQE Ammonia Odor

Exceptional, rapid removal of potentially toxic and annoying ammonia odors in refinery operations. Personnel safe, equipment compatible for effective ammonia control.

A large purified gas producer in Texas used our ammonia abatement product FQE™ Ammonia Odor to decontaminate an ammonia storage sphere of high concentrations of ammonia.


The storage vessel contained residual compressed ammonia and the airspace was saturated with gaseous ammonia. A 25% FQE Ammonia Odor in water mixture was prepared and circulated in the tank. The tank bottom was pumped to a 3D nozzle inserted into a sphere connection point and allowed to circulate and atomize the FQE Ammonia Odor product through-out the vessel.


The ammonia elimination was completed in less than 3 hours with the ammonia being reported at 0 ppm. The liquid was allowed to collect on the sphere bottom and pumped out to waste disposal without issue.


This process was scheduled for a 3 day process time, however it was completed within 6 hours – resulting in a significant cost and time savings to the client.
