9 Development Steps to Mark+ and its commercial status GAP Conference Beijing 2011

10 The new Lurgi FBDB TM Gasifier: Mark + LURGI FBDB TM Mark 4 Gasifier Outside diameter: 4.13 m Height: 12.5 m Design pressure: 40 barg Secunda (RSA), DGC (USA), Tianji (PRC), Yima (PRC), Angul (India) LURGI FBDB TM Mark + Gasifier Outside diameter: 5.05 m Height: 17.0 m Design pressure: 60 barg Next Generation 1950s

11 Lurgi New Gasification Module Evolution Step 2 Step 1 Name Mk4 (Mark4) Mk+ (Mark Plus) Nomenclature Mk4-HP40 Mk5E-HP60 Step 3 Raw Gas Loading (Nm³/h), dry Up to 60,000 Up to 120,000 Outside diameter (m) Overall Height (m) Design Pressure (barg)

12 Ruhr 100 Gasifier Pilot plant Ruhr 100 Dorsten / Germany Main characteristics Operating pressure 25 to 100 bar Diameter: 1.5 m 6,100 hours of operation 25,000 t of coal gasified 2 coal locks ( twin locks ) 12

13 Development diagram of Mk+ Rich references of Mk4 101 gasifiers globally Continuous technology improvement 1970s-2010) Quantify influence of diameter increase Latest MK4 (Design pressure: 40barg) STEP 1 Design improvement based on experience from Mk5 STEP 2 Continuous technology improvement for MK4 MK4 MK5 STEP 3 Quantify benefits of high pressure gasification Gasification database under high pressure and some special design features MK+ - Lurgi new FBDB Gasifier Ruhr-100 pilot plant maximum operation pressure: 100bar) 13

15 Lurgi FBDB TM Benefits of Mk+: Impact of Design Pressure and Dimension Results for a Chinese 4 BCMY SNG Project: Number of Lurgi FBDB TM gasification modules i.e. ~ 20 Mark + instead of ~ 40 Mark 4 Number of pieces of equipment greatly reduced (less number of modules) Benefits on the economics: Expected 10 % decrease of the SNG cost (60 barg vs 40 barg) Number of gasification modules halved Reduction of over 300 Equipment numbers Reduction of plot size Reduction of CAPEX up to 20% for the Lurgi FBDB TM process chain Higher Operating Pressure Reduces CAPEX and OPEX of Downstream units i.e. Rectisol and Methanation 15

16 Commercial interest in Mark+ Mark+ versus Mark 4: Lower coal and specific oxygen / steam consumption Higher specific methane yield Excellent savings in SNG and DRI applications NO demo unit required Ready for implementation on projects Resulting in: Mk+ being selected by a number of clients in China and India 16

17 Lurgi New Gasification Module Mark + LURGI Technologies for SNG Route Improved Rectisol Process 17

18 Lurgi Rectisol Process Adapted to Project Needs Intensive Development Program Undertaken Since 2009 Operational Expenses Reduced by More Than 30% Datang MTP Attributes of the Lurgi Rectisol Easy To Maintain Stable And Robust Operation On Line Cleaning Design Unique Know-how for Trace Components Characterization in The Feed Gas Carbon Dioxide Capture (Sequestration Ready) 18

19 Lurgi Rectisol Process Adapted to Project Needs Advantages of the Lurgi Rectisol Improved proprietary database Optimized Heat Exchanger Design Improved Heat Integration Reduced Capex Design References in China in 2010 Longyu LuoYang 19

20 Lurgi New Gasification Module Mark + LURGI Technologies for SNG Route Enhanced Methanation Process 20

21 Lurgi s References FBDB TM Gasification, Rectisol, Methanation Dakota Gasification Company Beulah, North Dakota, USA 14 x LURGI FBDB TM units Start-up: 1985 Coal: Lignite coal Products: Synthetic Natural Gas (SNG) and CO 2 for EOR (Weyburn/ Saskatchewan) 21

22 Enhanced Methanation Technology Lurgi and BASF Exclusive Partners on Methanation Technology Since 1974 Developed a High Temperature Process in 2010 Using Proprietary Catalyst Less Catalyst Volume Low Pressure Drop (Reflected in Lower Power Consumption) Long Catalyst Life and Robustness Medium Temperature Methanation High Temperature Methanation Catalyst G1 85 HT G1-85 Maximum Temperature ( o C) Guaranteed Catalyst Life 3 2 (Years) Recycle Compressor (Volume) 100 % 70% Power Consumption 100 % 40% Steam Superheating Temp. ( o C)

23 Enhanced Methanation Technology - Gains Higher Maximum Operating Temperature Allows Generation of Higher Temperature Steam Improved OPEX Reduced Recycle Gas Flow (Smaller Capex) Overall Gains for Customers Choice Choose Between MT- and HT- Processes Flexibility of Methanation Process to Upstream Gasification Type and Steam Quality Needs 23
