Underground storage project progresses in France
4 Jan 2011
London – Amiad Filtration Systems has completed the first stage of its project providing a salt leaching brine filtration system for an underground liquid hydrocarbon storage facility in France.
The underground facility - one of the largest and most strategic oil reserves in France - consists of stored liquid hydrocarbons (such as crude oil and gasoline) in 27 salt-leached caverns and has a capacity of 7.5 million cubic metres.
To create these underground caverns, the salt leaching brine must be filtered to meet the requirements for injection into the ocean - Amiad’s systems filter the brine to a level well within the regulations.
Amiad’s solution was also selected for its unique features, including:
- Chemical-free filtration solution, as the cavern is located in a protected natural forest
- Waste-free filtration process, the filter’s flush water is recycled during the leaching process
- Outdoor installation, the system is able to withstand extreme temperatures (-25 °C to 40°C), and avoids the cost of erecting a facility to house it
The installation is the third significant brine leaching solution supplied by Amiad - following installations at Pine Prairie Energy Center LLC in Louisiana, and SG Resources Mississippi LLC in Mississippi.
