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%.
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 + Energy
CH₃OCH₃ + 3O₂ → 2CO₂ + 3H₂O + Energy

Operation Instructions
- Handling: Always use DME in well-ventilated areas. Avoid inhalation or contact with skin.
- Storage: Store in sealed, pressurized containers away from direct sunlight or heat sources.
- Transport: Ensure compliance with safety regulations when transporting as a liquefied gas.
Safety Precautions
- Weaker anesthetic - concentrations above 7.5mg/L can cause mild discomfort, anesthesia in 23min, and loss of consciousness after 26min.
- Contact with skin may cause dermatitis. Operators should wear masks and rubber gloves.
- Highly flammable and explosive. Avoid fire sources and pressurized steam during production, processing, storage and transportation.
- Storage and transportation must comply with regulations for flammable materials.
