When it comes to odor management, simply cleaning the tank isn’t enough to remove the odors.

Prior to cleaning, storage tanks are vented to the atmosphere in order to reduce the internal gas content to a level below its lower explosion limit (LEL). This permits safe worker access. During venting, odors escape into the atmosphere creating a nuisance to nearby residents, businesses, and employees. Furthermore, storage tank cleaning results in production downtime that reduces plant profitability.

Saint Joseph, New Brunswick: Ecosorb® product is used during tank cleaning at this Canadian oil refinery to control odor. It was added via an air compressor airline into a tank and distributed using an air horn.

Ecosorb® products are effective on most odors associated with storage tank cleaning, including:

• Naptha
• Diesel
• Methyl tertiary butyl ether (MTBE)
• Crude oil
• Amines
• Phenols
• Formaldehyde
• Ammonia
• Sulfur dioxide

Crude Oil Storage Tanks.
Prior to cleaning tanks, they must be vented to lower the explosion limits – a process that releases crude oil odors to the atmosphere. An Ecosorb® system program can provide reliable control even in 500,000 bbl tanks.

Refinery Storage Tanks.
Spent caustic tanks at refineries often contain traces of naphtha and diesel that can escape during cleaning. In residential areas, this means costly delays waiting for favorable wind directions. Ecosorb® natural odor control products allow cleaning at any time.
