More likely to maintain a tight pattern of supply and demand in the future

Ethylene is one of the most simple unsaturated compounds, exist in plants in the nature of some organizations, the state of nature, is a kind of gas. Ethylene is a synthetic fiber, synthetic rubber, synthetic plastic (PE, PVC), basic chemical raw materials, synthesis of ethanol (alcohol) can be used in the manufacture of vinyl chloride, styrene and ethylene oxide, acetic acid, acetaldehyde, ethanol and explosives, etc., can also be used as fruit and vegetables ripening agent, is a kind of plant hormone has confirmed.

Ethylene is a kind of dangerous chemicals, transport need to use the compressor and cryogenic equipment, general is produced directly for the downstream products. Ethylene pipeline can be used, but the early stage of the infrastructure investment is larger, ethylene caused the overall logistics and trade volume is not large, but because of its important role in intermediates, upstream and downstream products are important commodity chemicals.

Ethylene raw materials are of ethane, propane and naphtha, downstream products are varied. The world ethylene production materials for crude oil, 70% and 25% for gas, 5% for coal. In the United States, the Middle East and north Africa, ethane and propane are relatively common ethylene production raw material, production technology by steam cracking method. Choice of the main causes of alkanes is these areas near the oil producing area, ethane and propane gas through the pipeline transported in short distance to petrochemical plant, transportation cost is more economic. And in the Asian region, naphtha is the most common of ethylene raw material, transportation usually adopt a tanker, the oil pipeline is not popular, the main production process for naphtha cracking method. Through different raw material and production process, the productivity of ethylene is not the same, the ethane and propane ethylene highest productivity, along with propylene. Naphtha, gasoline and other raw materials ethylene productivity is low, but additional product is relatively rich.

The biggest use of ethylene is the production of polyethylene, followed by epoxy ethane, ethylene glycol, polyvinyl chloride, styrene and other products, in terms of manufactured goods, synthetic fiber, synthetic rubber and synthetic plastics need ethylene.
