Dimethyl Ether price

Dimethyl Ether price What is dimethyl ether? Dimethyl ether is also called methoxymethane, dme gas or Dimethylaether, is an organic compound, a colorless and odorous flammable gas in the standard state, and its chemical formula is C2H6O or CH3-O-CH3. Relative vapor density (air is 1) 1.62, explosion range: 3.4鈥?7.0% (V/V), ignition temperature: 350掳C, dimethyl ether is easily soluble in water, alcohol and ether. DME is inert, non-corrosive, non-carcinogenic, and almost non-toxic. Dimethyl ether does not form peroxides on long-term exposure to air. It is a colorless gas under normal pressure and has a characteristic odor of ethers. As a substitute for freon, dimethyl ether is rapidly increasing in use in the aerosol and refrigerant industries. Dimethyl ether contains oxygen atoms, high thermal efficiency, complete combustion, clean tail gas without black smoke, and is an environmentally friendly fuel. With the rising price of petroleum and the environmental protection issues of vehicle and civil fuels, dimethyl ether, as a clean and environmentally friendly fuel, has attracted increasing attention from all walks of life. DME may become an important fuel in the near future. The price of petroleum products has been rising year after year, while the cost of coal-based dimethyl ether is low. DME will completely replace liquefied petroleum gas and partially replace diesel.  Since petroleum resources are non-renewable, research and development of alternative fuels for future vehicles are being conducted worldwide. The biggest potential market for future DME applications is as an alternative fuel for diesel. In contrast, the cetane number of conventional engine alternative fuels such as liquefied petroleum gas, natural gas, methanol, etc. is less than 10, which is only suitable for ignition engines. The cetane number content is an important indicator of diesel combustion performance. The cetane number of dimethyl ether is higher than that of diesel oil, which has excellent compressibility and is very suitable for compression ignition engines. DME can reduce nitrogen oxide emissions by replacing diesel oil. Realizing smokeless combustion, it is an ideal clean fuel for diesel engines. Using dimethyl ether, the tail gas does not need catalytic conversion treatment, and the emission of nitrogen oxides and black smoke particles can meet the requirements of ultra-low emission tail gas of California fuel vehicles, and can reduce engine noise. Studies have shown that existing car engines can use DME fuel with only a slight modification. Although DME costs more than diesel, it is less expensive and less polluting than low-polluting alternatives such as liquid propane. Using dimethyl ether as fuel requires only a slight improvement to the fuel system of the original diesel engine. Under the premise of maintaining the efficiency of the original diesel engine, the same output power, torque and fuel economy, without any exhaust gas recirculation system and exhaust gas treatment device, the nitrogen oxides can be greatly reduced to below 2.5g/(kW路h), At the same time, the contradiction between controlling nitrogen oxides and particulate emissions no longer exists, soot emissions are zero, there is no accelerated smoke, and particulate emissions are also greatly reduced. 聽 3. Dimethyl ether power generation: DME can also be used as a fuel for combined cycle power plants. Power generation systems generally use syngas as fuel. When the power generation load is low, the syngas can be converted into DME products, which can be conveniently stored for re-use or export at high load. The effect is similar to using methanol as fuel for combined cycle power generation. 聽Dimethyl Ether price website:http://www.julychem.com/dimethyl-ether/
