Ciel and its joint venture partners provide proven safe and effective No-Man-Entry, Robotic In-Service Crude Oil Tank Inspection and Tank Cleaning our additives for Sludge Conversion to Oil Supply. We save time and money.
Our additive characteristics is based on small, non-toxic, specially engineered carbon-based molecules which on contact allows for reliquefication of the full spectrum of hydrocarbon solids.
Our chemistry, is a green carbon electron sharing technology that weakens the Van der Waals attractive forces for asphaltenes and paraffins allowing a “phase change” from solid to liquid that effectively controls waxes and asphaltenes at a lower dosage rate. The chemistry also aids in the reduction of BS&W by rapid in-line separation of the water and oil phases, breaking difficult emulsions and eliminating foam.
When comparing our chemistry to traditional additives, surfactants, solvents and treatments may significantly raise your risk profile around your Health, Safety and Environment concerns and negatively impact downstream wastewater facilities.
Disadvantages of surfactants:
- Surfactants can be toxic to the environment
- Where our chemistry partitions 100% to the oil phase, surfactants will end up in the water recovered from tank cleaning and can cause issues with downstream processing, such as wastewater plants. Surfactants can cause emulsion issues and high BOD / COD problems as well as toxicity issues
- Surfactants are not as good at handling paraffins that stabilize emulsions in tank sludge. They can add surfactant dispersants for paraffin but they are not as effective as our non-toxic, specially engineered carbon-based molecules, which liquefies paraffin.
- Surfactants will often use heat to handle the paraffins, which is not needed with our additive.
- When Surfactants are used, downstream wastewater effects are a big concern. Our chemistry will help create a cleaner water with no chemicals in it, so no impact on wastewater plant.
With the combination of Robotics and the specific characteristics of out chemistry, along with the design of service prepared by our team, we have a practical, service for no-man-entry crude oil tank inspection and with tank cleaning using our chemistry for sludge conversion to oil supply (reliquefication of the full spectrum of hydrocarbon solids). Additionally referencing our partners Robotics are also capable of cleaning and inspection on all storage tanks refined products and water tanks. They have an extensive proven track record of safety and success.
Advanced Tanksweeps
Tanksweep methods are not to be confused with other methods where nozzles are introduced through holes cut in a tank roof or through a roof leg aperture. These methods are very frequently unsuccessful due to several reasons. The nozzles are small and are limited in their ability to pass large flows at a satisfactory pressure.
Each Tanksweep nozzle delivers 660m3/hour at 10 bar pressure. These nozzles rotate endlessly and their direction cannot be controlled or directed to where they may be needed. Tanksweep nozzles are directional and can be moved horizontally by a simple hand wheel to exactly where they are needed.
Tanksweeps are used when the liquid in the tank is 1.5m minimum above the tanksweep nozzle, this ensures that the steam from the nozzle cannot break through the fluid level into the airspace and therefore it is not necessary to inert the tank. Of course, if local legislations demand a tank be cleaned only when inert then this is also possible.
With Tanksweeps a tank up to 50m diameter can be cleaned with 2 x tanksweeps, a tank between 50 and 80m diameter requires 3 x tanksweeps, and a tank of 80-100m requires 4 x tanksweeps.
