Electrification is regarded as one of the solutions for decarbonization. To reduce the emissions of carbon dioxide from the steam cracking which is a conventional ethylene production process, the electrical heating furnace can be applied to the steam cracking called the electrified furnace. Here, to determine whether the electrified steam cracking is proper for carbon neutrality, the techno-economic analysis, life cycle assessment, and the analytic hierarchy process were implemented. The analysis was proceeded by the fourteen cases divided according to steam cracking, electrified steam cracking, and seven electricity generation methods. As a result, considering the technology development level, economic feasibility, and environmental impact, the best case was the steam cracking with hydropower, and the electrified steam cracking with hydropower, solar power, and wind power had high potential. As improving the technology development of the electrified furnace, the electrified steam cracking can be expected to become the proper ethylene production process to achieve carbon neutrality.

电气化被认为是脱碳的解决方案之一。为减少传统乙烯生产工艺蒸汽裂解产生的二氧化碳排放，可将电加热炉应用于蒸汽裂解，称为电炉。在这里，为了确定电气化蒸汽裂解是否适合碳中和，实施了技术经济分析、生命周期评估和层次分析法。按照蒸汽裂解、通电蒸汽裂解和七种发电方式划分的十四个案例进行分析。因此，综合考虑技术发展水平、经济可行性和环境影响，最好的情况是水电蒸汽裂解和带电蒸汽水电裂解，太阳能、风能潜力巨大。随着电炉技术发展的提高，电蒸汽裂解有望成为实现碳中和的乙烯生产工艺。
