对能效、煤耗和水耗等指标提出更高要求的煤制烯烃升级示范方案目前已获国务院审批,若采用多种技术方案来满足示范要求,煤制烯烃盈利空间恐将被压缩。这是记者从11月15～16日在北京举办的第四届煤制烯烃技术经济研讨会上获得的信息。煤制烯烃的技术可行性和经济性曾饱受质疑,经神华包头、神华宁煤、大唐多伦和中石化中原石化4套装置先后投产获得确认后,如今在升级示范方案面前再次面临考量。石油和化学工业规划院石化处副处长郑宝山透露,根据煤制烯烃升级示范要求,能源转化效率不低于40%,
The coal-to-olefins upgrade demonstration program, which put forward higher requirements on energy efficiency, coal consumption and water consumption, has been approved by the State Council. If a variety of technical solutions are adopted to meet the demonstration requirements, the profit margin of coal-to-olefin may be compressed. This is the information the reporter received from the 4th Coal and Alkene Technology Economic Symposium held in Beijing from November 15 to November 16. The feasibility and economy of coal-to-olefin technology have been questioned. After Shenhua Baotou, Shenhua Ningde Coal, Datang Duolun and Sinopec Zhongyuan Petrochemical have put into production four sets of devices and have been confirmed, they are now facing the challenge of upgrading their demonstration solutions. Petroleum and Chemical Industry Planning Institute Petrochemical Deputy Chief Zheng Baoshan revealed that according to coal-to-olefin upgrading demonstration requirements, energy conversion efficiency of not less than 40%
