Purpose

• Survey for satisfaction of customer using DME-LPG

• Check safety of LPG facilities using DME-LPG

• Legislation for using of DME-LPG as household and commercial use with this results

Executing institution : Korea Gas Safety Corporation(KGS)

• KGS is a public institution doing a safety check and analysis for facilities of City-gas,

LP-gas and High-pressure gas

• KGS did a survey for customer satisfaction and a safety check of facilities by visiting

all customers

Survey and safety check date

• Winter season : 2011. 2. 16 ~ 3. 11

• Summer season : 2011. 7. 15 ~ 8. 12

Conclusion

Results of the model supply business of DME-LPG

The thermal efficiency of DME-LPG and LPG is almost similar

→ So, most customers don’t feel difference with LPG in use of DME-LPG

By research for mixing degree of DME-LPG in tank lorry,

→ DME and LPG are very well mixed in the tank lorry

The survey shows very high satisfaction of customers(about 93%) in use of DME-

LPG

Problem caused by using DME-LPG in LPG facilities was not completely

happened

Future Plan

Now, on establishing of DME-LPG’s law for household and commercial use

Prepare to construct commercial DME plant in oversea gas field

Research for applying DME in other field(transportation, industrial use and so on)

coast of Mozambique.

Australia

Contract MOU for Preliminary Feasibility Study (’11. 7, ’12. 8)

→ Offshore DME production by DME FPSO and fixed DME plant

on Tassie Shoal

* PFS have been conducted for analysis of economic and technical feasibility of

producing DME on a commercial scale in Northern Australia.
