Fuel oils and Water Separation North Africa

Applications

High Flow, Real Time Oil from water Separation.
Oil refineries, Fuel Distribution Depots, and Power Stations Large sites processing oils, traditionally use oil water interceptors or gravity separators to separate oil spills and oil contained in run off water. Collection sumps are normally huge, deep concrete collectors incurring significant civil engineering costs and use gravity to conduct the oil water separation. Time is the significant factor and the quality of separation is often a poor. Cinc Solutions BV recently completed a project to separate quantities of oil from water utilizing the CS 500 liquid/liquid centrifuge, replacing gravity separation used in existing traditional sumps.

The problem
A fuel distribution depot / tank farm in North Africa has a central feed sump as a receiver from the sites run off water, contaminated by spilled fuels incurred during tanker replenishment and oil spilled into the tank farm bunds. Oil and water was accumulated in a central sump, this was pumped through a gravity separator which eventually discharged the oil, and cleaner water to appropriate tanks for disposal. During periods of heavy rainfall the sumps and the gravity separator could not cope and to prevent the collection tank overflowing, the volume had to be re directed from the dirty sump to the clean sump to prevent contamination of the land.

Solution
Increase the flow and provide a real time separation. This allowed the client to continually reduce the volume of contaminated water in the collection sump, ensuring plenty of capacity during periods of high rainfall, and apply high flow rate separation when the collection sump was filling. A CINC SOLUTIONS CENTRIFUGE MODEL CS 500 flowing at 35 m/3 hour.

Benefits
No carryover of free oil to the clean sump. Control over the flow out during periods of high rainfall. Prevents flooding and contamination of surrounding land The large sumps are essentially redundant; this reduces the amount of costs and space when considering a new design. There was no free oil in the water after the centrifuge. The dissolved BTEX can easily be removed with a polishing media filter.
