DME DME SynthesisSynthesis


• Commercial DME plants for fuel use licensed by TOYO started in Aug. 2003 and in March 2006. DME supply chain as LPG substitute was established at Lutianhua in China.

• Coal-based DME plants of 210,000t/y for Ningxia Coal Group and 140,000t/y for Shanxi Lanhua Clean Energy were started up in 2007 and 2008 respectively.

• DME synthesis technology is ready for market based on commercially proven experiences.

• A Jumbo DME Plant is combination of methanol plant and DME synthesis plant incorporating commercially proven technologies.

• The total investment cost of a Jumbo DME Plant is less and the production cost could be feasible compared with LNG and LPG.
