6. Technology

The dme project adopts advanced methanol gas-phase catalytic dehydration technology to produce fuel-grade dme with a concentration of more than 99.0%. The fuel-grade dme is further separated through a lightness removal tower (using high-efficiency corrugated rolled perforated plate filler) to obtain refined  with a concentration of 99.9% and high-purity  with a concentration of 99.99%.

7. Theory

The chemical stability and low molecular weight of DME make it highly reactive for applications in energy and chemical processes. Its combustion reaction is represented as follows:
CH₃OCH₃ + 3O₂ → 2CO₂ + 3H₂O + Energytext{CH₃OCH₃ + 3O₂ → 2CO₂ + 3H₂O + Energy}CH₃OCH₃ + 3O₂ → 2CO₂ + 3H₂O + Energy
