Remove odors from storage tanks as you clean.
Keep Smells From Escaping
Prior to cleaning, storage tanks are vented to the atmosphere to reduce internal gas content to a level below its lower explosion limit (LEL). This allows workers to access the tanks safely worker.
During venting, odors escape into the atmosphere creating a nuisance to nearby residents, businesses, and employees. Storage tank cleaning also results in production downtime that lowers plant profitability.
Benefits of Ecosorb
Ecosorb uses the natural power of plant oils to remove odors caused by tank cleaning.
Non-toxic, non-hazardous, biodegradable, non-flammable, and no harmful VOCs.
Proven by independent and customer labs to reduce volatile emissions.
Custom formulations for odorous gases from any industry.
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 odor control even in 500,000 barrel tanks.
Refinery Storage Tanks
Spent 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.
How to Use
There are many possible ways to use Ecosorb during tank cleaning, including the use of vaporization or atomizations systems. Tank venting with a “Coppus” fan is normally done prior to tank cleaning and Ecosorb can easily be injected into the direct-air line of the Coppus fan using a low volume chemical injection pump.
Some distributors and customers inject Ecosorb into a steam line, spray inside tanks, and reduce H2S levels. After an hour or so, emissions and odors have been eliminated to a low enough level to allow treated air to escape. A Canadian environmental company used a similar process to clear odors from ammonia storage tanks.
