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

4
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

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

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

I cant automate due to obstructions in my
tank
Myth or Fact?
14
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

Ill still need hot water to removeresidue even
with an automatedtank cleaner

17
Balancing the Factors Affecting Cleaning
Effectiveness
18
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)

19
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

20
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

21
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

23
The residue in my tank is prone to sparking so
automation is out of the question
Myth or Fact?
24
Tank Cleaning in Explosive Environments

• Read the owners manual
• Be sure the unit is grounded
• Use chemicals compatible with the units
  materials of construction
• Use explosion-proof motors

25
The residue in my tank is proneto sparking so
automation is outof the question
Myth or Fact?
26
I wont be able to verify that my tanks are
completely clean
Myth or Fact?
27
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

completely clean

29
The payback on automated tank cleaning is too
long
Myth or Fact?
30
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

31
The Payback for Automated Tank Cleaning

• Cleaner tank
• Shorter cycle time
• Lower energy costs
• Reduced chemical usage
• Lower labor costs
• Improved worker safety

32
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

33
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

long
