DME is used primarily as a propellant and a motor fuel alternative, DME is miscible with most organic solvents and has a high solubility in water. Recently, the use of DME as a fuel additive for diesel engines has been investigated due to its high volatility (desired for cold starting) and high cetane number. A feasibility study and design of a plant producing 99.9 wt% Dimethyl ether (DME) is to be performed by using simulation software Aspen Plus. The plant is designed which is capable of
