QATARGAS II: FULL SUPPLY CHAIN OVERVIEW

摘要

The Qatargas II LNG Project (QG II) is an exciting, 'full supply chain' joint venture, conceived by Qatar Petroleum (70%) and ExxonMobil (30%), which will set new standards for scale and economy of LNG production. The project will expand the existing Qatargas LNG facility at Ras Laffan, Qatar with the addition of two LNG trains, significantly larger than any previously built. Each train will have an LNG production capacity of approximately 7.8 million tonne/yr (MTA). Feed gas will come from the North Field, which is the largest non-associated gas field in the world. The onshore plant will extract LPGs (propane and butane), which will be fractionated, stored and exported from Ras Laffan. Lean LNG production is targeted for the United Kingdom market, using new, larger LNG transportation ships. A new receiving terminal in the UK will regasify the LNG and send out sales gas into the U. K. NTS (national gas transmission system). rnQG II shareholders have carefully evaluated available technologies and are implementing programs to successfully deploy various technical innovations, including: rn1. AP-X™ Hybrid LNG process, licensed from Air Products and Chemicals, Inc.,rn2. GE Frame 9E gas turbines with Dry Low NOx combustors driving refrigeration trains, rn3. Waste heat recovery and steam generation to improve overall thermal efficiency and further reduce total air emissions, and rn4. Larger more efficient LNG transportation ships rnA challenging schedule has been set to achieve new economies of scale, world-class air emissions performance, and the key project objectives of superior safety and environmental performance. First LNG sales in the U. K. are targeted for early 2008.
