1 Coal to Liquid a Viable Energy Alternative Theo L.K. Lee Headwaters CTL, LLC. Headwaters Energy Service, Utah USA India Energy Conference, New Delhi, Oct 3 & 4 2008 2 Scope of Presentation Why coal-to-liquid (CTL)? What is Headwaters DCL technology How to deal with high ash coals Strategy for implementing CTL project 3 Indian Oil Balance (BP Statistical Review) Indian oil import projected to be 6 million BPD in 2030 CTL is the pragmatic alternative to imported crude 4 India ranks 4th in coal reserves (mostly high ash coals) 5 Oil Gas Coal Coal remains the cheapest energy option 6 Recent steep increases in energy prices 7 Maximizing the Value of Coal Electricity Production A choice to make: Products 3 MWh electricity Total Value $120 $120 Fuel and Power Production 1 ton Coal Indirect Coal Liquefaction Products Value 0.083 MWh electricity $3 0.28 bbls naphtha $13 2.13 bbls diesel fuel $166 Total $182 Fuel, Power & Fertilizer Production Products Value 0.31 MWh electricity $12 0.30 bbls naphtha $14 1.58 bbls diesel fuel $123 0.30 t ammonium nitrate $105 Total $254 Liquid fuel provides greater mobility 8 CTL Technology Options Direct Coal Liquefaction (DCL) Coal + H2 Catalyst linear + ring Hydrocarbons (CxH2x) Coal/resid + H2 Catalyst linear + ring Hydrocarbons (CxH2x) Indirect Coal Liquefaction (ICL) 1. Gasification: Coal + O2 + Steam Syngas (H2 + CO) Catalyst 2. FT Synthesis: H2 + CO linear Hydrocarbons (CxH2x+2) Catalyst MTG Synth. : H2 + CO ring Hydrocarbons (CxH2x) Note: Practiced during WWII by Germany Hybrid Coal Liquefaction Integration of Direct and Indirect Coal Liquefaction Coal Properties and Product Objective influence choice of technology 9 Technology Performance DCL ICL (recycle) Hybrid Thermal Efficiency (%) 58.0 44.6 55.1 Liquid Yield, bbl/short ton 3.04 2.17 2.74 Carbon Utilization Efficiency, (%) 53 34 45 Plant CO2 Generation, (lbs/bbl product) 780 1560 1010 6 to 10 8 to 12 7 to 10 1.0 1.15 – 1.30 1.03 Water Consumption, (ton/ton product) Relative Capital Investment 10 Direct Coal Liquefaction Process H2S, NH3, COx Make-up Hydrogen Coal or coal-resid + disposable Fe catalyst Recycle H2 C1 – C2 LPG Gas Recovery Treatment HydroCoal treating Liquefaction H-Donor Slurry Slurry Fractionation De-Ashed Solvent Oil (DAO) De-ashing Refining Gasoline Diesel Fuel Heavy Vacuum Gas Oil (HVGO) Ash Reject Can be omitted for low ash coal 11 Petroleum Resid Hydrocracking Reactors Tonen Japan Husky, Canada PKN, Poland Pemex, Salamanca Mexico Pemex, Tula Mexico 12 Shenhua Inner Mongolia 20,000 BPD DCL Plant 2005 Early Headwaters’ 1st DCL license: End of 2008 Startup 13 Refined DCL Liquids - Shi, Yuhua (RIPP, Oct/04) Properties (5%, 90%) Naphtha (99,159oC ) Diesel (195, 277oC) Density, g/cm3 (20oC) Viscosity, mm2/s (20oC) S, ppm N, ppm Cetane No. Acidity mgKOH/100ml Oxidation Sludge, mg/100ml Flash Point, oC Cold Filter Plugging Point, oC Solidification Point, oC Compound Class Type Analysis, w% Paraffin Naphthlene Aromatics 0.7641 <0.5 <0.5 0.8648 3.69 (3 ~ 8) <5 (<2000) <1 46.7 (>45) 0.4 (<7) <0.3 (<2.5) 76 (>55) -9 (<-5) -26 (<-10) 26.7 68.3 5.0 13.3 81.9 4.8 14 Approach in Processing High Ash Indian Coal High ash coal: – lower efficiency – higher maintenance cost Ash reduction prior to DCL – Conventional coal washing – Coal/oil agglomeration – Solvent refined coal Blending with low ash or no ash feedstock – Gasification: petcoke (ash <30%) – DCL: petroleum resid (ash < 12%) (coal/oil co-processing) 15 Economic Analysis of ICL Project (US mine mouth location) Baler & O’Brien (Mar/2007) CAPEX $85K per barrel/day capacity OPEX $15/bbl Feedstock $10 short ton Total Liquid Yield 1.9 bbl/short ton Distillate Price 122% of WTI Equity 100% No CO2 Capture Breakeven crude oil price (WTI) = $48 To generate 12% after-tax IRR with no government incentive Economics of CTL project depend on coal type, scale, & location 16 Overview of Worldwide CTL Activities China: to startup first DCL plant; ICL-FT, MTG, MTO under design/construction; government controlled pace USA: mostly ICL with emerging interest in DCL Indonesia: Active partnership with Korean & Japanese companies India: Oil India Limited Assam DCL project; government coal block allocation RFP (both ICL and DCL proposals) Australia: UCG & ICL-FT activities Mongolia, Columbia, etc.. 17 CTL Strategies/Key Points for Success Coal reserve secured and accessible Proven technology and adequate security package Robust and experienced contractor Deep pocket sponsors for completion & performance risk Optimal financing structure (low debt/equity ratio) Sound risk allocation strategy Use derivatives to control commodity risk Positive government policy incentives SNC-Lavalin April 2008 18 19 Cost Breakdown of ICL – FT Plant Fischer-Tropsch Synthesis 12% Product Recovery/Refining 5% Power Block 18% Coal handling/Prep 9% Gas Cleaning & Conditioning 20% Syngas Total 56% Air Separation 9% Gasification 27% Baler & O’Brien (Mar/2007) $80 to 100K per barrel/day capacity (US location) 20
