The purpose of this study is to develop a process synthesis, simulation, and integration of a shale gas-to-DME plant by direct and indirect methods. In order to use DME as a fuel alternative, it must be produced at low cost in large quantities. Another way to produce DME is the direct synthesis of DME from syngas. Recently, the attention to DME has increased because of its potential in addressing energy security and environmental problems.ĭME is produced conventionally through two steps (indirect process) which are methanol synthesis and dehydration of the methanol to DME. Dimethyl ether is currently produced from natural gas, coal and biomass through synthesis gas as an intermediate. Dimethyl ether can be used in many areas such as power generation, transportation fuel, and domestic heating and cooking. Consequently, shale gas has become a competitive feedstock for usage as energy and production of chemicals and petrochemicals.Ī valuable product which may be obtained from shale gas is dimethyl ether (DME). Over the last decade, the U.S has witnessed substantial growth in shale gas production. In order to attain this goal, researchers continue to develop new technologies and methods in the field of sustainable energy. As the energy demand is increasing constantly, sustainable energy resources are needed to meet this demand and enable economic stability.
