Corpus Christi Liquefaction Expansion - Stage 3 Project
Corpus Christi Liquefaction Expansion -
Stage 3 Project
Corpus Christi Liquefaction
(Original Project In Construction)
Stage 3 Pipeline
• 22 miles long, 42 inches in diameter
• Parallel to 48-inch diameter pipeline being constructed for currently-authorized
Liquefaction Project
• Will connect
Terminal with
several interstate
and intrastate
pipelines
• Two electric-driven
compressors to be
added to Sinton
Compressor Station
What Is Liquefied Natural Gas (LNG)?
LNG is natural gas that has been super-cooled to
-260°F and changed from gas to liquid
Liquefaction reduces volume by 600-to-1
Stored cold in insulated containers at near atmospheric
pressure
Safe to store and transport
LNG is colorless, odorless,
non-corrosive, and non-toxic
Becomes lighter than air when vaporized
ConocoPhillips Optimized CascadeSM LNG Train
Process Advantages
• Reliability – design concept based on two 50% compressors for each refrigeration cycle
• Turn-down – Two-in-one concept provides for ~100% efficiency at 60-80% utilization
• Intermittency – fast start-up and cool-down
Proven, Reliable Design
• Bechtel/Conoco Phillips collaboration with 40+ year history
• Proven, reliable “template” design
• Kenai Alaska, 1969
• Atlantic LNG Trains 1, 2, 3 and 4, 2005
• Egyptian LNG Trains 1 & 2, 2005
• Darwin LNG, 2006
• Equatorial Guinea LNG, 2007
• Cheniere, Sabine Pass Liquefaction, under construction
• Angola LNG, under construction
• Currently under construction in Australia

3 Sabine Pass Liquefaction Construction
ConocoPhillips Optimized CascadeSM Process
1. The natural gas is received
at about 1100 psig and 70°F
2. CO2, H2S, water, and
mercury are removed to
prevent freezing and
damage
3. The natural gas is first
cooled to -25°F by a
propane refrigerant
4. Then to -130°F by ethylene
5. Heavy hydrocarbons which
may freeze in the LNG are
removed
6. The final cooling to -215°F
is done by a methane
refrigerant.
7. The LNG is pumped to the
LNG storage tanks where it
is “flashed” down to -256°F.

Benefits to the Public Interest
Stimulates local and regional economies • Direct creation of 2,000 to 3,000 engineering and construction jobs
Improves national balance of annual trade by between $9.8B and $15.8B (combined Liquefaction Project and Stage 3 Project)
Supports domestic natural gas productive capacity and promotes stability in natural gas pricing
Promotes liberalization of the global natural gas trade through fostering a global, liquid gas market
Advances national security of U.S. allies through diversification of global natural gas supplies
Potential to displace oil (and coal) for power generation applications, resulting in reduced global CO2 emissions
Stage 3 Project – Minimal Environmental Impacts
Majority of Stage 3 Project LNG Facilities to be developed within dredged material placement area approved for the Liquefaction Project.
Stage 3 Project will share marine facilities with the Liquefaction Project.
No new shoreline impacts. Stage 3 Pipeline to be located parallel to and share right-of-way with
currently authorized pipeline, thereby minimizing project footprint. Stage 3 Pipeline route avoids sensitive habitats. Minimal wetland
impacts. No impacts to Threatened or Endangered Species. No impacts to cultural resources.
LNG Shipping
Double-hulled state of the art tankers
LNG is stored in a special containment system within the inner hull
Kept at about 1.5 psi above atmospheric pressure at -260ºF
Use “boil-off” gas as onboard fuel
Many safety features for cargo containment & fire prevention
