DME Manufacturing
DME is produced from existing fossil resources as well as biogas, a renewable energy, and is called e-DME.
The physical properties of DME are similar to LPG, and when used as fuel, it is a very clean raw material that does not produce smoke or soot during combustion.
DME is liquefied at -25℃ at normal pressure and 5~6bar at room temperature, making it very easy to store and easy to vaporize, making it easy to use.
It is also used as an LPG-DME mixed fuel and has a cetane value similar to diesel fuel, so it is used as an alternative to diesel fuel.
DME is colorless, non-toxic, and harmless to the human body.
"In addition to the aerosol raw material and fuel markets where it is currently mainly used, it can also be used in the refrigerant production and foaming agent markets. Biofriends Inc.'s DME manufacturing process is
designed and constructed using its own technology. Using methanol as a raw material, DME is produced and purified through a
dehydration reaction in a reactor, and is sold and provided to consumers and companies upon order, eliminating harmful substances during the manufacturing and purification process. It is manufactured so that no substances are generated. Currently, the DME production plant with an annual capacity of 5,000 tons is operating at the Boeun production plant at rated capacity, and the design of a second plant is in progress with the goal of producing 10,000 tons per year in the first half of 2023."
DME Supply
BioFriends manufactures methanol into DME using the DME plant and transports it directly to the purchasing company. "Currently, our company deals with the aerosol, refrigerant, and LPG blended fuel markets, and in the future, we plan to contract and supply whenever a number of manufacturing and production markets that require DME emerge and expand."
