LNG Import Terminal In St. John, New Brunswick
• Scope: >5000 m of
cryogenic and utility piping
• Date: August 2008
• Process Temps.: -260°F (-162°C)
to ambient
• Design Goal: Condensation
control; flash-freeze protection of
fire-water lines in LNG spills
• Insulation: 2 layers (20 mm)
Cryogel-Z over PIR
• Results:
– Material was specified because of the reduced labor force, faster installation
schedule, and fire protection
– Contractor stated that wished he could have done 100% Cryogel, as it “would
have gone on five times faster”

Valves and Flanges on Offshore LNG Import Terminal
• Scope:
– 1500+ valves & flanges >2”
• Location:
– Southeast of Venice, Italy
• Process Temp.:
– -260°F (-162°C)
• Other Factors:
– Clashes and supply / logistical issues
with baseline material
• Insulation:
– 7-11 layers Cryogel Z
• Results:
– All material air-freighted to job site
within 4-weeks ARO
– 700 insulators trained on Cryogel
– All clashes resolved ahead of schedule

Insulating Double-Gimbaled
Cryogenic Flex Joints
Insulating Cryogenic Flex Joints
• Scope:
– 36” LNG flex joints
• Location:
– Mexico
• Temperature:
– -260°F (-162°C)
• Design Goals:
– Condensation control on a
doubly-gimbaled flex joint
for large bore pipe
• Insulation:
– 4-5” (11-13 layers) Cryogel Z
to match 8-9” of PIR
• Results:
– Insulated in Houston and trucked to Mexico
– Worked with EPC, joint manufacturer and contractor on the overall design

LNG Tank Risers
Insulating LNG Tank Risers
• Scope: 150’ of 24” and 12” pipe
• Process Temp.: -260°F (-162°C)
• Insulation:
– 2.8” (70 mm) Cryogel Z
• Other Factors:
– Frequent thermal cycling
– Only 3” of clearance between pipe
surface and tank stiffening rings
– All work done between LNG deliveries
– Insulated pipes pass through hoop
guides designed to limit sideways
deflection due to wind loads. Insulation
had to withstand compressive-, shear-,
and impact-loading
• Results:
– Lines are in-service; Tank 2 this year

Liquid Ethylene Sphere in Brazil
• Scope:
– 60’ ethylene sphere
• Location:
– Southern Brazil
• Temperature:
– -30°F (-34°C)
• Design Goals:
– Condensation control
– 90-min fire protection
• Insulation:
– 50 mm Cryogel Z +
10 mm Pyrogel XT +
galvanized steel jacket
• Results:
– Reduced thickness by 67%
– 20% faster installation than with spray foam
– Sproule Mfg. designed cut patterns, resulting in a 98.5% material yield

Super-Insulated Liquid Ethylene Vessel
• Scope: 10’ x 60’ ethylene bullet
• Location: Southampton, UK
• Design Goals:
– Maintain liquid during 6-week T/A without refill or refrigeration (BOG <5 kg/day)
– Passive fire protection
• Insulation Design:
– 13.4” (340 mm) of Cryogel,
jacketed with SS
• Results:
– Vessel was pre-insulated in
Manchester, then trucked
250 miles to Southampton
– Unit successfully installed
and operated during T/A
– Now in-service as just a
very well-insulated
ethylene storage vessel

Heat Exchanger Modules
• Location: Northern Alberta
• Scope: Three pre-insulated
heat exchanger modules
• Date: Mar, 2007
• Process Temp.: 250-400°F
• Design Goal: Heat conservation
• Insulation: 2” mineral wool ¾” Pyrogel
• Other Factors: Modules insulated in Kansas City; transported to Alberta
• Results:
– Insulation survives the abuse of long-distance road transport
– Thinner profile reduced interference near inlets, outlets, and structural supports

• Scope: 3 km of 24” pipe
• Date: Summer 2009
• Process Temp.: 300°C (570°F)
• Design Goal: Heat conservation
• Other Factors: All piping
was pre-insulated in Edmonton
and trucked 6 hours to remote
work site
• Results:
– Eliminated need for an on-site man camp
– Reduced effective labor rate from $200/hr to $45/hr
