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 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

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

SAGD Operation, Ft. McMurray, AB

• 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
