CDU – Crude Distillation Unit
• CDU - an atmospheric
pressure distillation tower.
This unit accepts a variety
of crude oils and distills
them into the primary
products including LPG,
naphtha, kerosene, light
gas oil and refined crude
• Heated crude condenses
at various levels in the
tower
• 250f
• 150 psig

Sentry Equipment Corp
Sampling Solutions • Specialty Heat Exchangers
VDU or vacuum
distillation unit is a
vacuum distillation
tower. This unit accepts
“reduced” crude
processed by the CDUs
and distills them into the
primary products
including LPG, naphtha,
kerosene, light gas oil
and refined crude
700 F typical
100 psig
VBC – Visbreaking Unit
•
•
•
•
Sentry Equipment Corp
Sampling Solutions • Specialty Heat Exchangers
VBC or Visbreaker is a
thermal cracking unit.
This unit accepts vacuum
tower “resid” or the very
viscous vacuum tower
bottoms and uses high
heat (800 F) to crack the
hydrocarbons into fuel oil,
naphtha and light gas oil
800 F typical
100 psig
Typically a patented
process (UOP, shell)
HTU – Hydrotreater Unit
• HTU or Hydrotreater uses a
recycled hydrogen stream
and catalyst to convert sulfur
compounds to hydrogen
sulfide, nitrogen to ammonia
and aromatic hydrocarbons to
stronger hydrocarbons. This
unit accepts vacuum tower
light and heavy gas oil and
converts them to gasoline,
kerosene and naphtha
• 200 F typical
• 200 PSIG liquids
• 1300 PSIG gases
Sentry Equipment Corp

CRU – Catalytic Unit
• CRU or catalytic
reforming unit
removes oxygen,
nitrogen and sulfur
from naphtha that
contaminates the
unit’s catalyst and
then converts it to
gasoline
• Up to 500 F typical
• 200 PSIG liquids
• Typically a patented
process (“Unifiner”,
etc.)

FCCU – Fluid Catalytic Cracking Unit
Sentry Equipment Corp
Sampling Solutions • Specialty Heat Exchangers
•
Fluid catalytic cracker
(FCC) uses high
temperature and
catalyst to crack heavy
gas oil mostly into
gasoline.
Hydrocracking uses
catalysts to react gas
oil and hydrogen
under high pressure
and high temperature
to make both jet fuel
and gasoline

Polymerization Unit
•
•
Sentry Equipment Corp
Sampling Solutions • Specialty Heat Exchangers
Polymerization in the petroleum
industry is the process of
converting light olefin gases
including ethylene, propylene, and
butylene into hydrocarbons of
higher molecular weight and
higher octane number that can be
used as gasoline blending stocks.
Polymerization combines two or
more identical olefin molecules to
form a single molecule with the
same elements in the same
proportions as the original
molecules. Polymerization may be
accomplished thermally or in the
presence of a catalyst at lower
temperatures.
Alkylation Unit
•
•
•
Sentry Equipment Corp
Sampling Solutions • Specialty Heat Exchangers
Alkylation combines lowmolecular-weight olefins
(primarily a mixture of
propylene and butylene)
with isobutene in the
presence of a catalyst,
either sulfuric acid or
hydrofluoric acid
For fuels blending
Various process methods

Typical Sampling Points
• Outlet of settling tank
• Solids outlet of clarifier
• Outlet of digester
Sentry Equipment Corp
Sampling Solutions • Specialty Heat Exchangers
Why Sample in a Wastewater
Plant?
• Control solids ratios at the digesters
– 70% of plant costs deal with the removal of
solids
– Digesting sludge reduces solids volumes
thus, less to incinerate
• Improve overall plant efficiency
• Cost control
• Truck load out verification
– Hauling costs are based on lbs of liquid
– Control the concentration of solids
Sentry Equipment Corp
Sampling Solutions • Specialty Heat Exchangers
Challenges With Sampling in a Wastewater
Plant
• Stinky and sloppy job
– Spigot under pressure = VERY MESSY!
• Manual samples are not representative due to human
variances and operators attempt to reduce messes
• Dozens of sampling points result in high labor costs
and inaccuracies (due to inconsistent composite
samples)
• Ergonomics (the ideal sample point is not always
located in an easily reachable location)
Sentry Equipment Corp
Sampling Solutions • Specialty Heat Exchangers
Why the ISOLOK®?
• ISOLOK® is the only sampler that can effectively sample sludge
from a pressurized line
• Automatically captures fixed sample volume at fixed time intervals
providing uniformity and consistency of sample for process control
(elimination of human error)
• Unit is simple, safe, and reliable
• Clean (eliminates material spillage)
• VERY low labor costs
– Each MANUAL grab sample typically takes 10 minutes
(including clean up) every couple of hours
– Sampling with the ISOLOK® typically only requires operators
to collect the containers ONCE per day!

Challenges With Sampling in a
Pharmaceutical Plant
• Obtaining a representative sample from a lined
reactor with high process temperature and pressure
/ vacuum
• Extracting sample from a device with a moving
agitator
• Often requires special materials of construction
– Hastelloy, titanium, AL6XN, etc
• Many sample points require “closed” sampling to
eliminate operator exposure to hazardous
conditions
Sentry Equipment Corp
Sampling Solutions • Specialty Heat Exchangers
Why Sentry Samplers?
• Wide variety of materials of construction available to
satisfy process conditions
– Special alloys
– Seal materials
• Ability to offer closed sampling solutions when required
– Needle/septum samplers
– ISOLOK®® - exchanged air is returned to process
through sample annulus
