Transcript

  • 1. BLABO process The BLABO® process
  • 2. BLABO process BLABO® in brief • Mobile and fully integrated process system • Combining automated tank cleaning and oil recovery • Patented • 2-4 containerised modules • Suitable for large ‘difficult-to-clean’ tanks • Oil types: crude, HFO, slop oil etc.
  • 3. BLABO process The BLABO process Suction module Recirculation module Fixed or floating roof tank Skimming module Separation module Auxiliary equipment Optional supply Nitrogen generator Office and workshop container Power generator, steam supply and other equipment Oil Water Solids Safe area Tank wall Hairpin pipe Pontoon Sump Sludge Support leg Vacuum pump Nozzle Pre-filter Feed pump Control panel Control panel Coalescing plates Control panel Control panel Booster pump Hydrocyclones Hydraulic unit Shell & tube heat exchanger Decanter Liquid/soids separation High-speed oil/water separation Directly to pipeline To waste water treatment facilityReturn to recirculation for water wash Gas return to tank Recovered oil To waste water treatment facility Plate heat exchanger
  • 4. BLABO process The BLABO® tank cleaning and oil recovery processes step-by-step

  • 8. BLABO process Mobilisation Sample nozzle distribution plan Back to diagram
  • 9. BLABO process Mobilisation Nozzles on tank roof Back to diagram
  • 10. BLABO process Mobilisation Hairpin pipe Back to diagram
  • 11. BLABO process Mobilisation View inside the tank to be cleaned Pontoon Extra nozzles Nozzle Hairpin pipe To BLABO Suction module Sump Sludge Support leg Tank wall Back to diagram From BLABO Re-circulation module
  • 12. BLABO process Fixed roof tanks Nozzle From BLABO Re-circulation module To BLABO Suction module Sump Sludge Tank wall Back to diagram
  • 13. BLABO process Mobilisation Safety precautions Strict personal, mechanical/electrical and environmental safety procedures are part of the Oreco training programme and must be completed before starting the process: • Fire prevention • Oxygen concentration in the tank • Definition of safety areas (ATEX and EEX) • Prevention of static electricity / inertisation • Personal protection equipment • Instruction in emergency procedures • Oil safety precautions Back to diagram
  • 14. BLABO process The BLABO® tank cleaning and oil recovery processes step-by-step
  • 15. BLABO process Tank blanketing BLABO Oreco NitroGen Nitrogen Tank cleaning nozzle Tank roof
  • 16. BLABO process A full NitroGen installation Air inlet Air compressor Refrigeration dryer Air buffer tank PSA separation units Nitrogen buffer tank Nitrogen outlet Filters Inlet pressure requirement of 7.5 bar Refrigeration dryer removes impurities from compressed air Stock of air to feed generator Separates the compressed air Stock of pure nitrogen
  • 17. BLABO process The BLABO® tank cleaning and oil recovery processes step-by-step
  • 18. BLABO process Desludging Purpose Purpose of the de-sludging phase: • First phase of the cleaning process ensuring maximum removal of the sludge in the tank. How is it done? • Starting with operating the nozzles closest to the feed pump. • Cutter stock is used to re-suspend waxy sludge, if needed. • Heating the sludge to fluidise it, if needed. Back to diagram
  • 19. BLABO process The BLABO® tank cleaning and oil recovery processes step-by-step
  • 20. BLABO process Cleaning Optimal cleaning result • Cleaning is up to 6 times faster compared to manual cleaning. • Unique washing pattern covers complete interior tank surface area. • Re-circulating sludge is used as cleaning media. • Programmed washing sequences Back to diagram
  • 21. BLABO process The BLABO® tank cleaning and oil recovery processes step-by-step
  • 22. BLABO process Separation Solid/Liquid and Liquid/Liquid Close to 100% of the hydrocarbons are recovered and can be re-processed. For disposal to on-site treatment facility. Mainly inorganic material (sand rust), however containing hydrocarbons. For further treatment or final deposition Back to diagram
