Electrification is part of process intensification being explored by the chemical industry to improve energy efficiency and to reduce greenhouse-gas emission. Ethylene production, using electrochemical-facilitated non-oxidative ethane dehydrogenation, is an emerging, but promising, process to facilitate electrification of the ethylene industry and represents the most untapped opportunity in the chemical industry. Herein, we highlight the low-temperature electrochemical ethylene production using solid-oxide membrane reactors/stacks (LoTempLene) and elucidate the opportunity of using it in the electrification trend. Detailed process simulation was conducted using Aspen Plus software, based on state-of-the-art results for energy and cost analysis, aiming to better understand the practical implications of the LoTempLene process versus conventional steam cracking. We also provide our perspective on the key challenges and possible solutions for low-temperature electrochemical ethylene production.

电气化是化学工业正在探索的过程强化的一部分，以提高能源效率并减少温室气体排放。使用电化学促进的非氧化乙烷脱氢进行乙烯生产，是一种新兴但有希望的方法，可促进乙烯工业的电气化，并且代表了化学工业中最未开发的机会。在本文中，我们重点介绍了使用固体氧化物膜反应器/烟囱（LoTempLene）进行低温电化学乙烯生产的方法，并阐明了在电气化趋势中使用它的机会。使用最新的能源和成本分析结果，使用Aspen Plus软件进行了详细的过程仿真，旨在更好地了解LoTempLene工艺与传统蒸汽裂解工艺相比的实际意义。我们还提供了有关低温电化学乙烯生产的关键挑战和可能解决方案的观点。
