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

• 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
refrigeration requirement–275 MW of power required for 7.8
MTPA of lean LNG + .85 MTPA of LPG
–Current technologies require 150 MW for 4.7 MTPA Train of rich LNG
