DME: Developments,
Opportunities and Challenges
What is DME? “Synthetic LPG”
Dimethyl-ether (DME)
Methane
Methanol
Water Propane
Butane
Hydrogen Carbon Oxygen
1.4 tons MeOH to 1 ton DME
LPG
About DME
• Burns like natural gas
• Handles like LPG
• Similar to methanol with respect to:
• Manufacturing technology
• Costs
• Petrochemical feedstock
• Environmentally friendly with
significant global consumer history as propellant.
• Clean burning
• Outstanding diesel alternative fuel
• Very large market potential as synthetic LPG, diesel alternative and fuel for power generation

Major Activity/Event
DME: clean and green
• HEALTH:
• non toxic, non carcinogenic
• Approved as consumer product propellant
• SAFETY
• Flammable liquid like LPG
• Similar safety guidelines and codes as LPG
• ENVIRONMENT
• Low emission fuel (LPG, Power, Diesel)
• Short half-life in atmosphere

Drivers for DME
Gas monetization Clean Coal utilization
Biomass conversion Methanol marketing
LPG alternative Ultimate diesel Power generation
Hydrogen carrier Chemical Feedstock
Multiple Markets Multiple Sources
Methanol and DME production
Syngas (CO+H2)
(DME)
Conventional Two Step Process
Natural Gas
Biomass Coal
Petroleum Coke
Methanol
• Same chemistry, different engineering
• Methanol to DME conversion is very simple
• Similar Capex and Opex (lower than GTL-FT!)
• Co-production feasible
• Choice of technologies
DME
Methanol and DME
Direct or Combined Processes
Ready technologies
DME as LPG blendstock
• DME/LPG blending work (BP, ENI)
• Completely miscible
• Below 20% DME, existing LPG infrastructure can be used
• THIS IS THE PRIMARY MARKET
• Simple marketing
• High value markets
• Large demand (>200 million T/yr market size)
DME and Methanol for Power Generation
• 1995-2000: Partnership with GE and EPDC; Studies with SW
• Multiple, detailed combustor tests
• DME is excellent gas turbine fuel
• GE and SW provide commercial
offerings of DME-fired E class and F class gas turbines
• GE and SW guarantee power
output, heat rate and performance
• DME/Methanol exhibit record efficiencies and low emissions

BP pioneering diesel demonstration
• 1992: Invention by Sorensen/Mikkelsen
• 1994: BP Demonstration in truck engine
• Partnership with HTAS, AVL, Navistar
• Proof of sootless, low NOx, quiet combustion
• “DME is diesel wonderfuel”
• Feb. 1995: Press conference and SAE paper #950061
• Ongoing collaboration with Volvo and AVL Powertrain
“DME is our preferred long term fuel.”
