Product Description

Diesel Gas LPG DME Dimethyl Ether Propellant For Liquefied Petroleum Custom

Product Introduction

Methoxymethane (DME) is an organic compound with a chemical formula of C₂H₆O. At room temperature and pressure, DME is a colorless gas with a slight ethereal aroma, but it can become a liquid under pressure. The gas has a higher density than air and can diffuse to a considerable distance at a lower level. Methoxymethane DME is very stable in the air, inert, non-corrosive, non-carcinogenic, and slightly toxic.

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.

Uses of Methoxymethane DME

Chemical Raw Material: DME is primarily used as a methylating agent for the production of dimethyl sulfate. Additionally, it can synthesize N,N-dimethylaniline, methyl acetate, acetic anhydride, ethylene Methoxymethane DME, and ethylene among other chemical raw materials.
Industrial Uses: DME serves as an alkylating agent, refrigerant, foaming agent, solvent, extractant, and leaching agent. Furthermore, it can be used as a substitute for composite ethanol for civilian use, and Freon aerosols.
Aerosol Propellant: In industries such as hair care, skin care, pharmaceuticals, and coatings, DME can be used as a propellant for various aerosols.
Fuel Additive: DME is promoted as a fuel additive abroad and has many unique applications in the pharmaceutical, dye, and pesticide industries.

Applications

Energy Sector:

Alternative Fuel: DME is an ideal clean fuel that can replace liquefied petroleum gas (LPG) and diesel. Due to its high combustion efficiency and low pollution emissions, it is regarded as a potential clean energy source for the future.
Fuel Cell Hydrogen Source: DME can also be used as a hydrogen source for fuel cells, generating hydrogen through reforming reactions for use in Proton Exchange Membrane Fuel Cells (PEMFCs) and other mobile power sources.

Technology

The Methoxymethane 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 ethre 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

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 your specific applications.
24/7 Customer Support: Dedicated team to address your queries anytime.

Production Process

The production of DME involves:

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 the 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.

Precautions

Avoid exposure to high temperatures to prevent unintentional vaporization.
Ensure leak-proof containers and proper safety protocols during handling.
Use flame arrestors in systems handling DME to prevent flashback.
Wear appropriate protective equipment (gloves, masks) during use.
