The Elvos system is designed to treat oily water slops for discharge onshore and offshore.

The system has 3 main stages.

Stage 1
Treatment by a decanter centrifuge to clarify the liquid and remove heavy solids discharging solids to a TCC or skip via an auger. This decanter can also be used for drilling mud treatment.

Stage 2
Processing through a high-speed disc stack centrifuge to split the fluid into 3 phases - oil, water and slurrified solids. The oil is recovered to a tank for recycling to the mud system or used as a lubricant for the cuttings feed to a TCC unit as required. The solids are discharged to the same as solids from stage 1. The water is returned to a mix tank for stage 3.

Stage 3
Final polishing of the water to remove trace oil and solids. Where needed, chemicals can be added to the effluent and mixed if required. The resultant fluid is filtered to give a clear effluent to be discharged overboard.

All testing is done manually (InfraCal Analyser) and conforms to all DECC regulations for the disposal of oily water offshore.

All equipment is certified for lifting offshore, however items outwith the Elvos container must be transported in DNV 2.71 or offshore approved containers when loading from boat to rig. Hook-up time is typically 2-3 days.

Benefits

  • Reduced impact on the environment
