Odor control for tank cleaning - Oil, Gas & Refineries
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.
Ecosorb products are effective on most odors associated with storage tank cleaning, including:
- Methyl tertiary butyl ether (MTBE)
- Crude oil
- 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.
