Specific energy consumption analysis in steam cracking for the ethylene production rocess

综合分析当前乙烯流程的能耗现状,以典型进料的乙烯生产流程为例分析不同原料、不同工艺技术的乙烯流程各单元的综合能耗、能量损失分析。重点研究石脑油裂解技术的研究进展及其综合能耗影响分析,指出当今蒸汽裂解工艺流程平均综合能耗还有约20%的节能空间,石脑油的高温热裂解部分采用先进的炉体和炉管材料等技术,可节约20%的能量,压缩和分离部分的改进加起来也可节省15%的能量。

Analysized the energy loss trend of ethylene process based on the typical feeds as an example,and emphasizes on the researching trends of different naphtha cracking technologies and total process energy consuming.At the same time,an overview of state-of-the-art naphtha cracking technologies showed that approximately 20% savings on the current average process energy use were possible.Advanced naphtha cracking technologies in the pyrolysis section,such as advanced coil and furnace materials,could together lead to up to approximately 20% savings on the process energy use by state-of-the-art technologies.Improvements in the compression and separation sections could together lead to up to approximately 15% savings.
