Abstract

Dimethyl ether can be used as a propellant, also can be used in diesel engines with the advantage of high efficiency, a high cetane number, and low exhaust emissions (no particulates, no Sulphur, and low NOx). Technical-quality DME is an alternative to liquefied petroleum gas (LPG). It has excellent combustion characteristics due to a low auto ignition temperature. Dimethyl ether has a cetane number of 55–60, DME can be used as a substitute for diesel fuel in a diesel engine. This simulation study is able to predict and describe the compositions of the final production rate, and the distribution of the main components in the final product. This allows the estimation of economic factors, related to the operation of the catalytic reactor. For the present study, DME production process is simulated in Aspen Hysys V8.8 environment. a fluid package is selected along with the components which are to be in the input stream. In the process, NTRL was selected as the fluid package as it isable to handle selected pure components (methanol, water and dimethyl ether). The equilibrium reaction was selected to describe conversion of methanol to DME reaction.
