Harm of dimethyl ether adulteration in liquefied petroleum gas

Dimethyl ether, also known as methyl ether, does not produce environmentally damaging gases during combustion and can be produced cheaply and in large quantities. It is expected to become one of the clean energy sources in the 21st century, and there has never been any problem in industrial, agricultural, medical and other wide applications. However, on the road to civil fuel, there are twists and turns, the cause is unexpectedly

It comes from a rubber gasket on the cylinder valve. In 2007, Shandong Provincial Bureau of quality Supervision, Shandong Provincial Construction Department and Shandong Province * * Department jointly issued documents to approve Linyi Jiutai Energy Dimethyl Ether as civil gas. In August of the same year, the Ministry of Construction issued the industry product standard "Dimethyl Ether for Urban Gas". In fact, these two policies only show that DME can be used as a civilian fuel, not how to use it. Gas prices are higher in the south.

In Guangdong, Chongqing, Fujian, Hainan and other places, dimethyl ether took the opportunity to flow into the liquefied petroleum gas market and was mixed with civil liquefied petroleum gas, with a maximum blending ratio of up to 80%. Because DME is an oxygenated fuel, it will oxidize the rubber gasket in the liquefied petroleum gas cylinder angle valve. According to the test results of the National Gas Appliance quality Inspection Center at the beginning of 2008, with the increase of the content of dimethyl ether, the outer rubber sealing ring of the cylinder valve

The shape size will gradually shrink and its sealing performance will be reduced. In March 2008, the AQSIQ issued the Circular on issues related to cylinder filling (quality Inspection Special letter [2008] No. 17). The notice clearly requires that liquefied petroleum gas cylinders shall not be filled with dimethyl ether, or unknown chemical additives shall be added to welded gas cylinders without authorization; the consistency of gas cylinder stamping marks and gas properties shall be carried out.

It is confirmed that all refitted gas cylinders shall not be used; filling units that refill gas cylinders such as adding dimethyl ether into liquefied petroleum gas cylinders and adding unknown chemical additives to welded gas cylinders shall be investigated and dealt with in accordance with the provisions of the regulations on Safety Supervision of Gas cylinders. Among many standards, the standard of dimethyl ether as a civil fuel has not been issued for a long time. According to the data released by the National Energy Administration, there are now more than 8 million people in the country.
