国内裂解C5产业链发展现状及趋势

Development status and trend of China’s cracking-sourced C5 fractions production chain

近年来国内乙烯产能剧增,产生大量副产裂解C5。多套裂解C5分离装置投产,延长了产业链,进一步提高了C5资源的附加值。保守估计,到2021年裂解C5新增约104万t,裂解C5分离利用途径将发生改变。阐述了国内裂解C5产业链的现状和未来发展趋势。

China’s ethylene capacity has soared in recent years,bringing about a large amount of cracking-sourced C5 fractions.Startups of several C5 separation facilities extend the production chain and further increase the added value of C5 resources.It is predicted conservatively that about 1.04 million tons of cracking-sourced C5 fractions will be additional in China by 2021,which will change the utilization pathway of cracking-sourced C5 fractions.The current situation and future development trend of China’s cracking-sourced C5 fractions production chain are expounded.
