对石脑油裂解和煤制烯烃竞争力量化分析方法的探讨

Probing into the Quantitative Method to Compare Competitiveness between Coal-to-Olefin Project and Naphtha-to-Olefin Project

2010年至今,世界能源价格经历了上涨、高位小幅震荡、快速下跌的过程,同期在"十二五"期间我国煤制烯烃产能大幅增长,成为烯烃市场重要的组成部分。文章以煤制烯烃、石脑油裂解成本构成分析为重点,定量分析相关变量对两者之间的竞争力变化的影响。

The world energy market price has experienced rising, range-bound in high price level and rapid fall since 2010. Meanwhile China has developed vast capacity of coal-to-olefin units, which compete with the naphtha-to- olefin units in the market. This article develops a quantitative method based on cost-analysis to compare the competitiveness between coal-to-olefin project and napbtha-to-olefin project.
