“…The production of DME is very similar to that of methanol; DME is produced through gasification of various renewable substances or fossil fuels, i.e. natural gas, coal, bio mass or other carbon containing materials [44,46]. However, the current production technology is costly and relatively energy inefficient.…”

“…[1,2] Furthermore, DME can be substituted for liquefied petroleum gasoline in residential cooking and also for natural gas in gas turbines. [3][4][5] The versatility of DME makes it a highly competitive alternative fuel. However, the process by which it is produced from biomass must be economical to achieve widespread commercialisation.…”

A ternary semicontinuous system for the separation of bio-dimethyl ether from methanol and water is presented. The performance of eight potential control configurations, including the application of temperature inferential control, is evaluated. Dynamic simulations of the semicontinuous system and associated control scheme demonstrate that the temperature inferential control configuration is effective in achieving the separation objectives while remaining within operational limits. The semicontinuous system using the inferential temperature control scheme is simulated and shown to be economically preferable to the traditional continuous process for a range of production rates.

“…DME was also found to be an excellent gas turbine fuel with emission properties comparable to natural gas [6]. DME-fuelled turbine also allows to achieve a significant performance improvement through thermochemical recuperation with 44% higher power output and an 8% decrease of the specific CO 2 emissions compared to the present plant [7]. However, DME is not a suitable fuel for spark-ignition (SI) engines due to its high cetane number, though the burning velocity is similar to hydrocarbon fuels [8]; the easily-induced knock would limit the operation of SI engines.…”

Permanent AbstractThis paper reviews the properties and application of di-methyl ether (DME) as a candidate fuel for compression-ignition engines. DME is produced by the conversion of various feedstock such as natural gas, coal, oil residues and bio-mass. To determine the technical feasibility of DME, the review compares its key properties with those of diesel fuel that are relevant to this application. DME's diesel engine-compatible properties are its high cetane number and low auto-ignition temperature. In addition, its simple chemical structure and high oxygen content result in soot-free combustion in engines. Fuel injection of DME can be achieved through both conventional mechanical and current common-rail systems but requires slight modification of the standard system to prevent corrosion and overcome low lubricity. The spray characteristics of DME enable its application to compression-ignition engines despite some differences in its properties such as easier evaporation and lower density. Overall, the low particulate matter production of DME provides adequate justification for its consideration as a candidate fuel in compression-ignition engines. Recent research and development shows comparable output performance to a diesel fuel led engine but with lower particulate emissions. NO x emissions from DME-fuelled engines can meet future regulations with high exhaust gas recirculation in combination with a lean NO x trap. Although more development work has focused on medium or heavy-duty engines, this paper provides a comprehensive review of the technical feasibility of DME as a candidate fuel for environmentally-friendly compression-ignition engines independent of size or application.
