Guangdong "dme Event" Re-tracking - Dimethyl Ether, Liquefied Petroleum Gas - Chemical

Occurred in Guangdong LPG DME blending impact of the incident in Henan, Shandong, Hubei, Sichuan, Guizhou, Hunan and other places in the diffusion of DME production enterprise with. Meanwhile, a growing number of industry began to seriously consider, in order to allow safe and effective DME to LPG camp, in order to make good use of the new fuel, has been formed to protect the market, all aspects should be done work out what.

2008 1 1st, Ministry of Construction promulgated live "town gas with dimethyl ether" industry standards, dimethyl ether, liquefied petroleum gas as an alternative fuel has a legal status. But three months later, the State General Administration of Quality Supervision, Inspection and Quarantine issued "on the issue of notification for filling gas cylinders," clearly prohibits adding LPG DME require cylinders to be special, because "the civil Liquefied petroleum gas mixed with dimethyl ether filled LPG cylinders after a serious breach "to Safety Supervision", and could lead to leakage of LPG cylinders and welding gas cylinder valves severe corrosion to the safe use of gas cylinders great danger. " However, AQSIQ DME filling in the blocked part of the same vulnerability, has not introduced a national standard, such as the proportion of a mixture of dimethyl ether, filling the standards, which led directly to the field of non-standard civil state. Since then, Guangdong, Zhejiang, Jiangsu and issued the "add on the non-liquefied gas of dimethyl ether in the notice," Some cities have even set up a hotline. Guangdong liquefied gas mixing dimethyl ether from the hotline to report the incident is cited out.

It is understood, also reported in Guangdong, called different, there are a number of provinces and cities to go in the DME before use of local standards. 

December 1, 2009, Quality and Technology Supervision published "DME composite fuel LPG" local standards into effect. Clearly defined standards, dimethyl ether compound in the liquefied petroleum gas fuel in the proportion of not more than 20%; DME composite fuel LPG cylinders and LPG cylinders in color, logo and so on more than 10 differences . Chongqing Municipal Bureau of Quality Supervision also help enterprises to adopt bar code technology on computer networks and DME composite fuel cylinders used to track the entire process of security management services, to protect its proprietary standard cylinder filling. To combat infringement and Chongqing Municipal Research Institute of Metrology quality testing out the "liquefied petroleum gas of dimethyl ether Determination Act," local standards, to have a legal basis to combat illegal. Thus, Chongqing, dimethyl ether, "how to use" the problem is not solved, liquefied petroleum gas fuel dimethyl ether complex security applications and market regulation has also been policy support.
Industry believes that DME is now sorely lacking in standards. The development of standards should be complementary, targeted. For example, since the problem lies in Guangdong cylinder Rubber Mat, then that can not be targeted to solve this problem?

National Liquefied Petroleum Gas Standards and Technology Committee, said Mr Tsang Chiu told reporters, to meet the DME's "special gas, special bottles, special valves, special" town gas of dimethyl ether need to use "liquid 2 ether cylinders "and" liquefied DME valve "The introduction of these two standards, so as to form a standard system. Fortunately, Tsang Cheung cylinder according to the National Standardization Technical Committee of the two national standards were sent for screening phase.

According to industry analysis, at present, the domestic production of dimethyl ether over 600 million tons per year. Last year, the market demand of DME is only about 2 million tons, nearly 2 / 3 of capacity idle. If the delay in introduction of national standards for DME businesses may be drowned.
