1
Tanks, Drums, and Vessels Unit 9
2
Learning Objectives TLW be able to describe the following about tanks, drums, and vessels used in the process industry: –Types –Uses –Materials of Construction –Monitoring and Maintenance –Hazards and Mitigations
3
Types Tanks Drums Vessels –Reactors –Distillation columns
4
Tanks, Drums, and Vessels Used for Storing Inputs (Raw Materials) Outputs (Products, Co-Products, Intermediates) Waste Recoverable waste Two types of Storage Tanks Atmospheric Pressurized
5
Materials of Construction Tanks and vessels are usually always made of metal. –Thickness increases as does pressure –Special alloys for corrosives Drums –Metal –Plastic for corrosives, additives –Cardboard - additives –DOT specs
6
Terms for Tanks, Drums, and Vessels Floating Roof Sphere Foam Chamber Sump (Possum Belly) Mixer Gauge Hatch Manway or Manhole Blanket Vapor Recovery Vortex Breaker Baffle Weir Boot
7
Vessels and Pressure Cylinders or drum shaped – generally atmospheric tanks High volatility materials – stored in pressurized tanks Round tanks (sphere) - pressure Bullet and spherical tanks - pressure Hemispheroids – low pressure Spheroids – low pressure

19
Hazards Overfilling Putting in wrong or off spec material Misalignment of blanket system Misalignment of pump system Pulling a vacuum while emptying a tank Overpressuring a tank Static electricity (dust or vapor explosion) Corrosion or mechanical damage
20
Hazards Describe potential impacts of these hazards on last –Individual –Equipment –Production (Quality) –Environment
21
Reactors Where Chemical Reactions Occur –Fixed Bed –Stirred –Fluidized bed reactor –Shell and Tube
22
Fixed Bed Reactor
23
Fixed bed reactor
24
Stirred Reactor
25
Fluidized Bed Reactor
26
Fluidized- Bed Reactor
27
Shell and Tube
28
Dikes, Firewalls and Containment Walls Contain materials Isolate Minimize damage Protect people, assets, and environment
29
Tank Dikes
30
Monitoring and Maintenance Abnormal noise – pinging/popping Abnormal heat Monitor levels and pressures Vibrations – pumps/mixers Check firewalls, sumps and drains, drain valves on dikes - rainfall Odors/leaks Corrosion checks, paint
