  1. Automated Tank Cleaning… Myth or Fact?

  2. Non-Automated Tank Cleaning • Manual Cleaning • Worker safety issues • Time (is money) • Repeatability • Fill & Drain • Large volumes of water/cleaning solution • Sometimes must be heated • Slow • Repeatability

  3. Automated Tank Cleaning • Fully Automated CIP • Completely automated system • Multiple cycles • Spray nozzle or tank cleaning device • Portable Systems • Simple components • Pump /fluid delivery system • Spray nozzle or tank cleaning device • Mobile

  4. Myth or Fact? “My tanks are too big (or too small)for an automated solution”

  5. Tanks of All Sizes Can BeAutomatically Cleaned

  6. Selecting the Right EquipmentAutomated Units for Cleaning Tanks with Dia. Ranging from 2’ to 100’ are Available Low-Impact Tank Cleaners & Nozzles for Tanks Up to 25’ in Dia. Medium-Impact Tank Cleaners for Tanks Up to 60’ in Dia. High-Impact Tank Cleaners for Tanks Up to 100’ in Dia. Tank Cleaning Nozzles for Rinsing Tanks with Dia. From 2’ to 16’

  7. Myth or Fact? “My tanks are too big (or too small)for an automated solution”

  8. Myth or Fact? “Automated cleaning won’t really get my tanks clean”

  9. Proper Specification Ensures Effective Cleaning • Important Selection Criteria • Correct throw distance • Proper impact • Lowest possible flow • Right spray pattern • Complete coverage of desired surfaces • Repeatability

  11. Myth or Fact? “Automated cleaning won’t really get my tanks clean” “

  12. Myth or Fact? “I can’t automate due to obstructions in my tank”

  13. Preventing “Shadowing” • Account for Internal Obstructions • Carefully select position • Consider multiple units • Use deflected sprays • Other manageable restrictions • Size or location of access ports • Unusual tank shape • Extremely tall or long tanks

  14. Myth or Fact? “I can’t automate due to obstructions in my tank”

  15. Myth or Fact? “I’ll still need hot water to removeresidue even with an automatedtank cleaner”

  16. Balancing the Factors Affecting Cleaning Effectiveness

  17. High Temperature • Decreases the bond between soil and surface • Decreases soil viscosity • Increases soil solubility • Increases chemical reaction rate (may allow for shorter cycle time)

  18. Cleaning Time • Duration that cleaning solution is in contact with equipment surface • Factors that influence duration • Chemical concentration – correct type of cleaner for soil removal • Impact force • Water pressure • Flow rate • Nozzle selection • Temperature - to maximize reaction rate of cleaning solution

  19. Chemical Concentration • Varies based on chemical selected, type of soil and surface to be cleaned • Concentration normally reduced as time and temperature increase • Lower concentration means less chemical is used and cost is reduced

  20. Spray Impact – An Alternative to High Temperatures • Increasing spray impact may allow decreases in • Temperature • Chemical concentration • Time • Double spray impact force by: • Doubling liquid flow rate • Quadrupling liquid pressure • Increasing impact instead of temperature can save thousands by decreasing energy costs

  21. Myth or Fact? “I’ll still need hot water to removeresidue even with an automatedtank cleaner”

  22. Myth or Fact? “The residue in my tank is prone to sparking so automation is out of the question”

  23. Tank Cleaning in Explosive Environments • Read the owners manual • Be sure the unit is grounded • Use chemicals compatible with the unit’s materials of construction • Use explosion-proof motors

  24. Myth or Fact? “The residue in my tank is proneto sparking so automation is outof the question”

  25. Myth or Fact? “I won’t be able to verify that my tanks are completely clean”

  26. Monitoring Devices Verify Cleaning • Acoustic sensors can be installed on tank exterior to detect • Rotation failure • Changes in rotation frequency • Changes in spray pressure • Clogged nozzles • Audible / visual alarms notify operators when change detected • Swab tests also possible

  27. Myth or Fact? “I won’t be able to verify that my tanks are completely clean”

  28. Myth or Fact? “The payback on automated tank cleaning is too long”

  29. The true cost of manual or fill and drain methods $Water + energy to heat water $ Chemicals $ Labor $ Disposal $ Lost Production Time $ Re-cleaning Tanks $Scrap Product = True cost

  30. The Payback for Automated Tank Cleaning • Cleaner tank • Shorter cycle time • Lower energy costs • Reduced chemical usage • Lower labor costs • Improved worker safety

  31. Payback Example – Chemical Processor • Situation • 3200 gallon reactors needed cleaning after every batch • CIP system failed to clean effectively at 1000 psi • Manual cleaning was required after automated cleaning to ensure cleaning • This combination was expensive, time consuming and dangerous

  32. Payback Example – Chemical Processor • Solution • High pressure rotary tank cleaning nozzle used, operating at 1800 psi • Pneumatic insertion/retractable device eliminated any need for personnel to enter tank • Result • Cleaning time reduced from 2 hrs to 10 min • Additional production time paid for equipment in just a few months

  33. Myth or Fact? “The payback on automated tank cleaning is too long”

  34. I can’t automate because… • My tanks are too big (or small)

  35. I can’t automate because… • My tanks are too big (or small) • My tanks won’t get clean

  36. I can’t automate because… • My tanks are too big (or small) • My tanks won’t get clean • I’ve got obstructions in my tank

  37. I can’t automate because… • My tanks are too big (or small) • My tanks won’t get clean • I’ve got obstructions in my tank • I’ll still need hot water to remove residue

  38. I can’t automate because… • My tanks are too big (or small) • My tanks won’t get clean • I’ve got obstructions in my tank • I’ll still need hot water to remove residue • The residue in my tank is prone to sparking

  39. I can’t automate because… • My tanks are too big (or small) • My tanks won’t get clean • I’ve got obstructions in my tank • I’ll still need hot water to remove residue • The residue in my tank is prone to sparking • I won’t be able to verify my tanks are clean

  40. I can’t automate because… • My tanks are too big (or small) • My tanks won’t get clean • I’ve got obstructions in my tank • I’ll still need hot water to remove residue • The residue in my tank is prone to sparking • I won’t be able to verify my tanks are clean • The payback is too long

  41. I can’t automate because… • My tanks are too big (or small) • My tanks won’t get clean • I’ve got obstructions in my tank • I’ll still need hot water to remove residue • The residue in my tank is prone to sparking • I won’t be able to verify my tanks are clean • The payback is too long FINAL SCORE: 6 “myths”, 1 “maybe”
