What is DME? “Synthetic LPG”

Dimethyl-ether (DME)

Methane

Methanol

Water Propane

Butane

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

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

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

(9)

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)

(10)

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.”
