Ethylene is one of the most important basic organic chemical raw materials, widely used in the petrochemical and chemical industries.
Main Uses
Petrochemical Raw Material: Used in the production of polyethylene (PE)
Chemical Synthesis: Used to prepare ethylene glycol, ethanol, acetaldehyde, etc.
Plastics and Resin Industry: Used as a basic monomer for various polymer materials
Welding and Cutting: Used as industrial fuel gas
Agricultural Applications: Used as a plant growth regulator (industrial use)
Ethylene is a highly flammable olefin gas that readily forms explosive mixtures in air. It must be stored, transported, and used strictly in accordance with flammable gas regulations.
Main Risks:
Extremely flammable; can ignite or explode upon contact with an ignition source or static electricity.
High concentrations may cause asphyxiation due to oxygen deficiency.
Liquid ethylene contact with skin may cause frostbite.
It tends to accumulate in confined or low-lying spaces after leakage.
Protection Recommendations:
Use explosion-proof equipment and maintain good ventilation.
Avoid inhaling high concentrations of the gas.
Wear protective gloves and safety glasses during handling.
Keep away from open flames, sparks, and static electricity.
Storage and Transportation:
Store in compliant pressure-resistant steel cylinders or cryogenic storage tanks.
Keep away from ignition sources, heat sources, and strong oxidizers.
Transport and manage in accordance with flammable gas regulations.
