近年来世界苯乙烯生产能力稳步增长,2012年已超过3255万吨/年。亚洲地区特别是中国苯乙烯生产和需求增长迅猛。2012年中国苯乙烯产能超过650万吨/年,产量约490万吨,表观消费量约850万吨,产品自给率约58%。预计2012～2017年,随着亚洲和中东新装置的投产,我国苯乙烯企业将面临越来越大的挑战,国内市场竞争日趋激烈。我国苯乙烯行业应提高资源综合利用程度和装置生产规模,从而增强国际竞争力。
In recent years, the production capacity of styrene in the world has increased steadily, exceeding 32.55 million tons / year in 2012. Styrene production and demand in Asia, especially China, is growing rapidly. In 2012, the production capacity of styrene in China exceeded 6.5 million tons / year, the output was 4.9 million tons, the apparent consumption was 8.5 million tons and the product self-sufficiency rate was 58%. It is estimated that from 2012 to 2017, with the commissioning of new installations in Asia and the Middle East, styrene enterprises in our country will face more and more big challenges, and the competition in the domestic market will become fiercer and fiercer. China’s styrene industry should improve the comprehensive utilization of resources and equipment production scale, thereby enhancing the international competitiveness.
