4 DME: an environmentally-friendly fuel Completely safe with no adverse impact on health Decomposes in the atmosphere in several tens of hours No sulfur content No direct carbon bonds (CH 3 -O-CH 3 ) No problems expanding use No concern over ozone layer depletion (alternative to CFCs) No SOx emission from combustion No particulate matter (PM) or soot emission from combustion DME is a clean burning alternative to LPG and diesel. 4 AEGPL Conference Nice 6-8 June 2007 F.

9 DME and other X-to-liquids competition DME is the simpliest XTL product and one of the most promising XTL way GTL GTDME CTL CTDME BTL Capital Intensity (K$/bbl/d(*)) (K$/bbl/d) Yield (HHV) CO2 (TCo2 emitted/tep of Product) Concawe Report Conv.

10 DME and XTL Competitors (TTW) (Tank-to-Wheels analysis) The "best in class" is obtained from DME with an adapted Diesel engine, with g CO 2eq /km 10 AEGPL Conference Nice 6-8 June 2007 F. Bollon Source: Tank-to-Wheels report March 2007 Concawe Eucar

11 DME at the gates of Europe China is building new capacities of DME and already using it mixed with LPG. This DME is mainly produced from methanol (made from coal) or from imported methanol A Japanese consortium (Total 10%) is on the way to build a DME plant in Niigata made from ex-gas methanol Korea has made some laboratory tests on DME India is checking DME for LPG/DME blends Egypt with Methanex is planning to build a DME plant Iran planned to build a DME plant in the South of Iran Turkey and Russia are working on DME Sweden is working on DME from biomass 11 AEGPL Conference Nice 6-8 June 2007 F.

12 DME/LPG properties Evaluation tests conducted by Japan LPG Center for some LPG appliances: Combustion characteristics Operating performance of burner safety device According to Japan LPG Center and for cooking appliances, the upper limit for DME in the DME/LPG mixture is assumed to be about 20% to 25% wt DME (without appliances modifications) Totalgaz is currently testing DME/LPG blends to verify those announcements 12 AEGPL Conference Nice 6-8 June 2007 F. Bollon

13 DME/LPG blends properties DME/LPG blends with 20 to 30% weight DME Compatible with most of the metals Compatible with some polymers but not all the ones used for LPG (these polymers are mainly used for the seals of LPG equipment) Stable in motionless conditions Combustion possible with some LPG burners but with a scale-downed efficiency Some problem of combustion of the residue remaining in cylinders with some DME/LPG blends 13 AEGPL Conference Nice 6-8 June 2007 F. Bollon

14 DME/LPG blends properties According to the Chinese producers replacing 1 kg of LPG by 1 kg of DME does not change significantly the duration for boiling 1 liter of water The cost of DME could be reduced dramatically by the scale-up of the capacity of DME plant But the price of methanol can be a limitation to the reduction of the production cost of DME 14 AEGPL Conference Nice 6-8 June 2007 F. Bollon

15 DME as alternative to diesel Test runs of DME trucks and buses in Japan 10 buses using DME in Shanghai from 8 May ,000 buses using DME in Shanghai in 2008? Volvo trucks / Nissan Diesel Isuzu (subsidiary of Toyota) 15 AEGPL Conference Nice 6-8 June 2007 F. Bollon

16 DME standardization The increase of DME as fuels in China, Japan and progressively in some other countries implies some international standards in order to ensure a global openness and transparency in the international commerce of DME The Technical Committee on Chemical Products of the Japan Industrial Standards Committee has already established a tentative standard for DME as fuel under the number TS K 0011 in But this Committee agreed that DME as alternative to diesel and DME as alternative to LPG may have separate technical specification and that the TS K 0011 is mainly a proposal for DME as diesel. 16 AEGPL Conference Nice 6-8 June 2007 F. Bollon

17 DME standardization China is working on some standards for pure DME and will issue some national standards soon IDA (International DME Association) has established a DME standardization group for following up the standardization prepared by other groups ISO/TC28 will start soon a DME working group about DME specification 17 AEGPL Conference Nice 6-8 June 2007 F.

18 Total is also involved in a commercial plant in Japan the Niigata project Project : Build a plant producing 80 kt/y DME from imported methanol through dehydration process, in MGC s existing plant. Participants are Japan DME group (MGC, Itochu, JGC, MHI) and other Japanese companies (Japex, Toyota Tsusho, Taiyo oil and Mitsubishi Chemical) Total s participation is 10% through Total DME Japan KK Starting-up in mid 2008 Japan Niigata Sea of Japan Tokyo Pacific Ocean Objective : Promote and develop the use of DME for : LPG or Distillate substitutes in Industry Diesel Transport Fuel (Heavy - Duty Trucks, Bus and small Trucks, Fleets) Diesel Power Generation systems 18 AEGPL Conference Nice 6-8 June 2007 F.
