Qatargas II DevelopmentQatargas II: Project Overview
Gas LNG LNG Gas to
Pipeline
•QP and ExxonMobil signed HOA in 2002 to supply two LNG trains to the U.K.
•Project made possible through :+World’s largest non-associated gas field +Qatar’s commitment to LNG business growth+Implementation of new cost effective technology+Unparalleled LNG delivery record
•Economies of scale give project a unique advantage to enable entry into new markets at competitive prices+Large LNG Trains - Planning Basis: 7 to 8 MTA+Large LNG Carriers - Planning Basis: 200,000M3
•Full Supply Chain Project+Agreements include provisions for regas and marketing of gas

Qatargas II DevelopmentQGII Technical Innovations
• AP–X TM Hybrid LNG Process, licensed from Air Products and Chemicals, Inc.,
• GE Frame 9E gas turbines with Dry Low NOx combustors,
• 45 MW electric motor/generators with VFD’s, allowing constant LNG production, year-round
• Waste Heat Recovery to improve overall thermal efficiency and further reduce total air emissions, and
• Larger more efficient LNG transportation ships
• Structured technology qualification program to bring new technologies into practice

• New refrigeration process required for larger train capacities
–Extension of Existing Technology–Combines LNG and Air Separation
Technologies–Uses Two Spiral Wound Heat
Exchangers (SWHE)• Three refrigeration services
–Propane (45oC to -30oC)–Mixed hydrocarbons (-30oC to -
114oC)–Gaseous nitrogen (-114oC to -
160oC)• New process + large capacity = large
