    • QNB Economics economics@qnb.com.qa 18 January 2013Global interest in GTL expected to growLast week Doha hosted the first World Gas-to-Liquids much smaller and in South Africa and Malaysia,(GTL) Congress. The event comes at a time of operated by PetroSA and Shell respectively.heightened interest in the industry, according to QNBGroup. Recent landmark developments include the Interest in GTL has come in three waves, according tocommissioning of the second train of Pearl GTL in QNB Group. The first was in the early 1990s, whenQatar, moves by Qatar Airways to utilise GTL as jet the South African and Malaysian plants werefuel and plans for new GTL plants in the US and launched. The second wave was in the early 2000s,elsewhere. when the current plants in Qatar were envisaged, as well as a 33,000 b/d project by Chevron and Sasol inThe GTL process converts natural gas into refined Nigeria, due to be commissioned this year.liquid fuels, such as kerosene and diesel.

However, high capital LNG, affected by several factors such plant size anddevelopment costs limited its application except in the potentially volatile prices of construction materials.situations where countries lacking oil reserves needed The GTL conversion process also consumes some ofsecurity of fuel supplies.
