In the beginning of 2010, the strict investigation event in Guangdong province made DME stand in the teeth of the storm again, which also proved that the DME enterprises appeal to new policies supporting them. While the management environment is getting worse, it is the most urgent matter to base on new application and seek the self-salvation way of the industry. At the very time of LPG industry recovery, and the methanol and DME industry hitting the bottom, China ChemNet, together with Guangdong Oil &Gas Associtation, cooperate again to hold the third international MDL market summit (http://news.chemnet.com/list/zt/industry/erjiamiyingwen/index.html). You are all welcome to join our conference to analyze the new problem, discuss the new way out and seek the self-salvation of the industry, by concentrating on the theme of DME application in the industrialization and gas community.
