Characteristics

Environmentally Friendly: Combustion produces only carbon dioxide and water, with no sulfur oxides or particulate emissions.
High Purity: Suitable for use in sensitive applications like aerosol propellants or chemical intermediates.
Energy Efficient: High calorific value, making it a suitable alternative to traditional fuels.
Easily Transportable: Can be stored and transported as a liquid under moderate pressure.

Advantages

Clean Energy: Emits no soot, making it ideal for environmentally sensitive applications.
Versatile Usage: Compatible with various industrial, automotive, and domestic applications.
Cost-Effective: Economical alternative to liquefied petroleum gas (LPG) and diesel.
Safe Storage: Stable under normal conditions with minimal risk of degradation.
Reliable Supply: Produced using abundant resources ensuring consistent availability.

Applications

Fuel: Replacement for LPG in domestic/industrial cooking; alternative diesel fuel for automotive and power generation.
Aerosol Propellant: Widely used in cosmetics, pharmaceuticals, and household sprays.
Chemical Feedstock: Used in synthesis of dimethyl sulfate, acetic acid, and other intermediates.
Refrigerant: Efficient cooling agent in refrigeration systems.
Welding and Cutting: Fuel for oxy-DME welding applications.

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 ether with a concentration of 99.9% and high-purity ether 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

Service

Customized Solutions: Tailored specifications for different industries.
Logistics Support: Safe and efficient transport of DME worldwide.
Technical Assistance: On-site and remote troubleshooting for specific applications.
24/7 Customer Support: Dedicated team to address queries anytime.

Production Process

Methanol dehydration under controlled conditions using advanced solid acid catalysts.
Purification of the final product to ensure high purity levels (>99.99%).
Storage in pressurized tanks for distribution.

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.
