Online mechanical desludging of storage tanks
Remove sludge from crude oil storage tanks without taking them out of service for long, and without anyone entering the tank. The recovered oil is blended back into receipt oil.
The challenge of tank sludge
Crude storage tanks slowly accumulate sediment and water that settle into sludge. It reduces capacity, contaminates the product and creates operational problems.
Traditional cleaning needs extended downtime, which disrupts production and exposes workers to hazardous conditions.
How online mechanical desludging works
Remote operation
No human entry into the tank.
High-pressure jetting
Specialised nozzles break down sludge and transfer it to a process tank for treatment.
Minimal downtime
The work is scheduled for periods when the tank is not in use.
Oil recovered
Treated sludge yields good-quality oil that is blended with incoming oil and sent to refineries once within permissible limits.
Benefits
- Workers are protected from hazardous conditions
- Tanks stay in use and production continues
- Cleaning time and cost are reduced
- Waste is minimised and regulations are met
