Dimethyl Ether, Liquefied Petroleum Gas

Occurred in Guangdong LPG DME blending affect of the incident in Henan, Shandong, Hubei, Sichuan, Guizhou, Hunan and other places in the diffusion of DME production enterprise with. In the meantime, a rising variety of business started to severely consider, so as to allow secure and efficient DME to LPG camp, with a view to make good use of the new gasoline, has been formed to protect the market, all aspects needs to be done work out what.

GB: ought to grasp the possibility to put the market back legs don’t drag

Inside the tower and packing2008 1 1st, Ministry of Building promulgated live “city fuel with dimethyl ether” trade standards, dimethyl ether, liquefied petroleum fuel instead gasoline has a authorized standing. But three months later, the State Normal Administration of Quality Supervision, Inspection and Quarantine issued “on the problem of notification for filling gas cylinders,” clearly prohibits including LPG DME require cylinders to be particular, because “the civil Liquefied petroleum gasoline combined with dimethyl ether crammed LPG cylinders after a severe breach “to Security Supervision”, and will result in leakage of LPG cylinders and welding gas cylinder valves extreme corrosion to the protected use of gasoline cylinders nice hazard. ” Nonetheless, AQSIQ DME filling within the blocked part of the identical vulnerability, has not launched a nationwide standard, such as the proportion of a mixture of dimethyl ether, filling the requirements, which led directly to the sphere of non-customary civil state. Since then, Guangdong, Zhejiang, Jiangsu and issued the “add on the non-liquefied gasoline of dimethyl ether within the discover,” Some cities have even arrange 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, referred to as different, there are various provinces and cities to go in the DME before use of native requirements. December 1, 2009, High quality and Technology Supervision published “DME composite fuel LPG” local standards into impact. Clearly outlined requirements, dimethyl ether compound within the liquefied petroleum gas fuel within the proportion of not more than 20%; DME composite gasoline LPG cylinders and LPG cylinders in color, brand and so on greater than 10 differences . Chongqing Municipal Bureau of High quality Supervision also help enterprises to undertake bar code technology on computer networks and DME composite fuel cylinders used to trace all the technique of security administration providers, to protect its proprietary commonplace cylinder filling. To fight infringement and Chongqing Municipal Analysis Institute of Metrology high quality testing out the “liquefied petroleum gas of dimethyl ether Dedication Act,” local standards, to have a legal foundation to combat illegal. Thus, Chongqing, dimethyl ether, “how to use” the issue is just not solved, liquefied petroleum gas gasoline dimethyl ether complex security functions and market regulation has also been coverage help.

Business believes that DME is now sorely missing in standards. The development of requirements ought to be complementary, Refinery Equipment targeted. For instance, since the issue lies in Guangdong cylinder Rubber Mat, then that can’t be targeted to solve this downside?

National Liquefied Petroleum Gas Requirements and Expertise Committee, stated Mr Tsang Chiu told reporters, to satisfy the DME’s “particular gas, special bottles, particular valves, particular” city fuel of dimethyl ether want to make use of “liquid 2 ether cylinders “and” liquefied DME valve “The introduction of those two standards, in order to form a normal system. Luckily, Tsang Cheung cylinder according to the National Standardization Technical Committee of the 2 nationwide requirements had been sent for screening part.

Based on trade evaluation, at present, the home manufacturing of dimethyl ether over 600 million tons per year. Final yr, the market demand of DME is just about 2 million tons, practically 2 / 3 of capability idle. If the delay in introduction of national standards for DME businesses may be drowned.
