In 2014, the proportion of the global ethylene project with naphtha and light diesel oil was 49.6%, down 0.6 percentage points from 2013.The proportion of heavy materials in the Middle East has increased;The proportion of heavy materials in Asia is still down.The global ethylene industry is expected to enter a new cycle of business cycles in 2017.In 2014, 4 sets of new large-scale ethylene plants were put into production in the world, and the annual production capacity was 6.4 million tons per year. In the United States, ethylene expansion capacity increased by more than 1.5 million tons/year;China has four sets of coal-producing olefin installations, and new ethylene production capacity is 1.15 million tons per year.By 2020, the share of global methanol olefin is expected to reach 20%, of which coal is about 16%.
In the future, the increase of ethylene production in China mainly depends on coal chemical industry, and the uncertainty of steam cracking route is obviously increased.2020 years ago, China's new ethylene production capacity is given priority to with methanol to olefins, coal to olefin from 2015 to 2020 is expected to new ethylene production capacity of 5.19 million tons/year, predicts 2020, the domestic ethylene production capacity will reach 35.6 million tons/year, equivalent demand at about 47.6 million tons/year.
It is understood that due to the rapid development of methanol to olefins unit, its future in the domestic share increase rapidly, by 2015 will reach 14% share of the methanol to olefins, 9% higher than that of 2013, of which coal to olefin accounts for about 11%.
